If you’re a pool professional designing high-performance systems, choosing the right plumbing components is essential. One such component is the true 3-inch valve, now available from Hayward. Unlike traditional 2.5-inch valves that may restrict flow, Hayward’s 3-inch PSV series valves are specifically built to handle high-flow systems efficiently.

Many pool systems use piping labeled as 2.5 or 3 inches, but not all valves offer a true 3-inch internal flow path. The Hayward PSV3S3, PSV2S3, and PSCV2S3 models are the first true 3-inch diverter, 2-way, and check valves in the industry. These valves allow for flow rates up to 230 gallons per minute with minimal head loss. Benefits of a 3-inch valve include: supports larger plumbing systems with higher flow rates, reduces restriction and energy loss compared to smaller valves, and are compatible with high-performance pumps and heaters. They are ideal for high-end residential and commercial pools. Installing the correct valve size helps maintain the efficiency of the overall system and prevents bottlenecks in circulation.

Hayward’s PSV series offers advanced design and materials built for long-term durability and high-performance flow. Features which include true 3-inch internal diameter for maximum water flow, chemical-resistant CPVC valve body built to handle harsh pool environments and ergonomic handle design for smooth control make the PSV series of valves ideal for most pools. Clear closed port indication for easy service and operation, reduced installation time with no need for extra couplings, and fewer glue joints means fewer failure points and lower risk of leaks make it perfect for builders and servicers. These features are designed to save time on the job, reduce long-term maintenance, and improve hydraulic performance.

Some key considerations that indicate a pool may need 3-inch valves are high-flow pool systems with large pumps or multiple return lines, heater or feature circuits with significant water volume, upgraded residential systems using 3-inch plumbing throughout and solar pool heating systems with large plumbing runs. In any system using 3-inch pipe, installing a 2.5-inch valve defeats the purpose and introduces unnecessary restriction. Upgrading to a true 3-inch valve maintains consistency and efficiency.

To get the most out of a 3-inch valve, follow these professional installation tips:

Use true 3-inch plumbing throughout the system for best results

Avoid unnecessary reducers or sharp bends near the valve

Plan for clearance around the valve handle for easy adjustments

Make use of fewer glue joints by taking advantage of the extended ports

Inspect the valve’s flow direction and port labels before gluing

Keep spare O-rings and seals on hand for maintenance

Check local codes and compatibility with your system design

With fewer glue joints and a clear handle indicator, Hayward’s valve design helps installers complete jobs faster and with fewer errors.

Even a great product can underperform if installed incorrectly. Avoid mistakes such as: 

Don’t use a 3-inch valve on a system with mostly 2-inch plumbing

Avoid over-gluing or using excessive sealant near moving parts

Ensure valves are accessible for future maintenance or service

Don’t assume every 3-inch valve has the same flow capacity

If you’re working on high-flow or large-scale pool installations, a true 3-inch valve should be your standard. Hayward’s PSV series offers the performance, durability, and installation benefits pool professionals need. Ready to spec your next project with the right valve? Choose the Hayward 3-inch PSV and future-proof your plumbing system.

For years, hydrotherapy in residential pools has largely been confined to one familiar place — the spa. Builders added therapy jets, bench seating, and spillover spas to create dedicated areas for relaxation and recovery. While effective, the hydrotherapy experience traditionally remained isolated to a small section of the backyard environment.

That concept is beginning to change.

Today’s homeowners increasingly view their pools as wellness destinations rather than simply recreational amenities. They want environments that support physical health, stress reduction, recovery, fitness, and immersive outdoor living. As wellness-centered design continues to influence the pool industry, builders are searching for innovative ways to create experiences that extend beyond traditional pool features.

Riverflow’s BlueOrbit system represents a major step in that evolution.

Rather than concentrating hydrotherapy in one stationary location, BlueOrbit introduces gentle circulating movement throughout the entire pool. The result is a soothing, resort-inspired water experience that transforms still water into a dynamic wellness environment.

Built on Riverflow’s decades of expertise in current-generation technology, BlueOrbit is helping redefine how homeowners interact with water.

The Shift Toward Wellness-Driven Pool Design

Over the last decade, the residential pool market has undergone a significant transformation. Homeowners no longer see pools solely as entertainment spaces or backyard focal points. Increasingly, they are investing in outdoor environments designed to support healthier lifestyles and everyday well-being.

Cold plunges, recovery pools, swim-in-place systems, and hydrotherapy features are becoming central parts of the design conversation. Builders report that wellness amenities are now being discussed during the earliest stages of project planning rather than as optional upgrades added later.

This shift reflects broader consumer interest in wellness-centered living. Homeowners want spaces that encourage movement, relaxation, mindfulness, and recovery — all within the comfort of their own backyard.

BlueOrbit aligns perfectly with this emerging demand.

Instead of creating a static pool environment, the system introduces subtle movement that encourages interaction with the water itself. The circulating current creates a calming sensation similar to floating in a gentle river or drifting in ocean currents, helping homeowners experience their pool in an entirely new way.

For builders and designers, this creates an opportunity to offer something that feels innovative, experiential, and highly differentiated.

How BlueOrbit Works:

Gentle Movement Throughout the Entire Pool

Unlike traditional swim current systems designed for athletic resistance and high-powered exercise, BlueOrbit focuses on softer movement and sensory comfort.

The system creates a smooth circular current that flows continuously throughout the vessel. Rather than producing a concentrated stream of water, BlueOrbit generates a subtle circulating motion that gently moves swimmers through the pool.

The experience is immersive without feeling overpowering.

Users can float naturally with the current, walk against the flow for low-impact exercise, or simply enjoy the sensation of moving water surrounding them. The movement remains smooth, quiet, and relaxing, making the pool feel more alive and interactive.

Because the current extends throughout the entire vessel, the hydrotherapy experience becomes communal rather than isolated. Families, guests, and homeowners can all participate simultaneously rather than taking turns using a designated therapy seat or spa station.

This broader application of moving water opens new possibilities for both residential and commercial pool design.

Why Moving Water Matters

The Physical Benefits of Circulation and Resistance

Water has long been recognized as one of the most effective environments for low-impact physical activity. Buoyancy naturally reduces stress on joints while still providing resistance that supports muscle engagement and improved circulation.

BlueOrbit enhances those benefits by introducing continuous movement into the swimming environment.

Even gentle current encourages the body to make constant micro-adjustments in posture and balance. Walking through moving water engages stabilizing muscles, promotes mobility, and increases resistance without the strain associated with land-based exercise.

For homeowners interested in active recovery, rehabilitation, or low-impact fitness, this type of movement can add significant functional value to the pool.

At the same time, the experience remains approachable for all ages and activity levels. BlueOrbit is not designed exclusively for athletes or competitive swimmers. Instead, it creates an inclusive wellness environment that prioritizes comfort, relaxation, and everyday enjoyment.

Beyond Fitness: The Mental Wellness Connection

Creating More Restorative Pool Environments

The appeal of moving water extends beyond physical wellness alone.

The sound, sensation, and visual movement of circulating water can have a calming psychological effect that encourages relaxation and stress reduction. Many homeowners already associate moving water with restorative experiences found at luxury resorts, spas, and wellness retreats.

BlueOrbit brings that sensation directly into the residential backyard.

The subtle circulation creates a more immersive sensory environment, helping transform the pool from a static visual feature into an active experience. Homeowners often spend more time in environments that feel engaging and comfortable, and moving water naturally invites interaction.

As outdoor living spaces continue evolving into wellness-centered retreats, systems like BlueOrbit help builders create emotional connections between homeowners and their pool environments.

That emotional engagement is increasingly becoming a key differentiator in luxury pool design.

Built on Riverflow Innovation

Riverflow has long been recognized as a leader in advanced water movement technology. Its systems are used in swim-in-place pools, lazy rivers, commercial aquatic environments, waterparks, and high-end residential projects around the world.

That experience in controlled water movement provided the foundation for BlueOrbit’s development.

Over the years, Riverflow observed that many homeowners enjoyed not only the athletic functionality of swim currents, but also the natural sensation of circulating water itself. That insight helped inspire a new direction — one centered less on resistance training and more on relaxation, wellness, and immersive movement.

BlueOrbit applies Riverflow’s hydraulic engineering expertise to create a softer, quieter, and more universally appealing experience.

Builders also benefit from Riverflow’s reputation for:

• Quiet operation
• Reliable performance
• Advanced hydraulic modeling
• Flexible installation capabilities
• Proven engineering support

For designers seeking to elevate their projects with experiential water features, BlueOrbit offers a compelling new design tool backed by an established industry leader.

The Future of Wellness Pools

As the pool industry continues moving toward wellness-centered design, the role of moving water is expanding rapidly.

Homeowners increasingly expect pools to do more than look beautiful. They want environments that improve how they feel physically and mentally while creating memorable everyday experiences.

BlueOrbit answers that demand by transforming the entire vessel into a living, moving wellness environment.

It is not simply a feature added onto the pool — it changes the nature of the pool experience itself.

For builders, designers, and aquatic professionals, that creates exciting opportunities to deliver projects that feel modern, differentiated, and emotionally impactful.

As hydrotherapy evolves beyond the spa and into the entire swimming environment, BlueOrbit represents the next generation of wellness-focused pool design.

When homeowners step outside and look at their swimming pool, they aren’t thinking about pumps, plumbing, or automation panels mounted on the equipment pad. What they see first is the water. Is it clear? Does it sparkle in the sunlight? Does it look inviting enough that they want to jump in right away? That moment of visual clarity is often the single most powerful signal homeowners receive about how well their pool is being cared for.

For pool professionals, that clarity represents the culmination of everything happening behind the scenes. Filtration systems are removing debris and particles, sanitizers are keeping the water safe, and balanced chemistry is protecting both swimmers and equipment. When those elements work together properly, the result is water that looks effortless — even though maintaining it requires skill and attention.

Yann Morvan, Product Line Leader for Smart Water Quality at Pentair Pool, believes water clarity ultimately becomes the defining measure of a service professional’s work.

“Water quality is essentially the signature of a pool professional’s work,” Morvan said. “It’s the most visible — or sometimes invisible — proof of their craftsmanship. If the water is always perfect every time a homeowner steps outside, that builds deep trust.”

That trust has a direct impact on customer relationships. When water quality is consistent, homeowners stop worrying about their pool and simply enjoy it. But when water turns cloudy or chemistry slips out of balance, confidence can erode quickly.

“Cloudy or unbalanced water is often the number one reason clients switch service providers,” Morvan said. “So the stakes are real.”

The Elements That Create Perfect Water Quality

Clarity Is Only the Beginning

When Pentair talks about “perfect water,” Morvan explains that the concept extends far beyond visual clarity. While homeowners may judge their pool primarily by appearance, the reality is that water quality is the result of multiple systems working in harmony.

“Perfect water is really an orchestra of different elements all working together,” Morvan said.

Clarity may be the most obvious indicator, but it only reflects what’s happening deeper within the system. Balanced chemistry plays a critical role, ensuring that pH, alkalinity, calcium hardness, and stabilizer levels remain within the proper range. Those factors protect pool surfaces and equipment while also helping sanitizers work effectively.

“You’ve got balance — the pH, the alkalinity, the calcium hardness, the CYA — all working together to protect both swimmers and the equipment,” Morvan said.

Sanitization: The Invisible Layer

The final component of healthy pool water is sanitization, which ensures the water remains safe for swimmers. Most pools rely on chlorine to eliminate contaminants, bacteria, and organic waste introduced through regular use.

“And then you’ve got sanitization — the invisible layer, typically chlorine, that makes the water genuinely safe,” Morvan said.

When clarity, balance, and sanitization are all working together, the difference becomes immediately noticeable.

“You get what I’d describe as a resort pool experience,” Morvan said. “That silky feel. No harsh smell. Water that just invites you in.”

If any one of those elements drifts out of balance, the experience begins to break down.

“The water might look dull, smell off, or worse — become unsafe,” he said.

Understanding Saltwater Pools

Debunking the “Chlorine-Free” Myth

Advances in pool technology have made it easier to maintain consistent water quality. One of the biggest changes over the past decade has been the widespread adoption of salt chlorine generators. Today, more than seventy percent of new inground pools in the United States are installed with salt systems.

Despite their popularity, Morvan says misconceptions about saltwater pools remain common.

“The biggest misconception we see is that salt pools are chlorine-free,” Morvan said. “That’s completely false.”

Saltwater pools still rely on chlorine to sanitize the water. The difference lies in how that chlorine is introduced into the system.

“Salt systems produce chlorine on-site from the dissolved salt in the water rather than requiring you to manually add tablets or liquid chlorine,” Morvan explained.

Instead of periodic spikes caused by adding chemicals, salt systems generate chlorine continuously.

“A salt system microdoses constantly,” Morvan said. “That gives you a much more stable chlorine level around the clock.”

How Salty Is a Salt Pool?

Another common misunderstanding involves the salt concentration itself. Many homeowners assume saltwater pools resemble ocean water. In reality, the difference is dramatic.

“A properly maintained saltwater pool runs at around 3,500 parts per million of salt,” Morvan said. “The ocean sits at roughly 35,000 parts per million.”

At those levels, most swimmers can’t even taste the salt.

“What people notice instead is that the water feels softer and more comfortable,” he said.

Salt systems reduce the need for manual chlorine additions, but Morvan cautions that they still require attention.

“Salt systems dramatically reduce maintenance, but they are not maintenance-free,” he said. “You still need to monitor pH, monitor salt levels, and eventually replace the cell.”

A Chlorine Factory Built Into the Pool

How Salt Chlorination Works

Salt chlorination works through a process known as electrolysis. Salt — sodium chloride — is dissolved directly into the pool water. As the water circulates through the plumbing system, it passes through a salt cell containing electrically charged plates.

“The salt cell has titanium blades coated with a special compound,” Morvan explained. “When electricity passes through those blades, it separates the chlorine from the sodium, and once it’s done sanitizing, it converts back into salt,” Morvan said. “So it’s essentially a closed loop.”

Because the salt is recycled during the process, it rarely needs to be replaced except when diluted through splash-out, backwashing, or heavy rainfall.

Designed With Service Pros in Mind

Easier Repairs Through Modular Design

Recent improvements in salt chlorine generators have focused heavily on making the equipment easier to service. Feedback from builders and technicians played a major role in the redesign of Pentair’s IntelliChlor units.

“Builders and service professionals told us they wanted equipment that fit the realities of the pad and the service call,” Morvan said.

One major improvement is the modular electronics design.

“The electronics module now clips on and off,” Morvan said. “If there’s an issue, you replace just that component instead of the whole cell.”

Improved Sensors and Diagnostics

Sensor technology has also been upgraded. The new sensor module measures temperature, water flow, and salinity simultaneously, providing more accurate information to technicians.

“The salinity reading is now about 98 percent as accurate as a lab-grade tester,” Morvan said.

The system also includes more than twenty diagnostic codes visible directly on the display, helping technicians identify problems quickly.

“The unit can tell you whether the issue is the cell, the power center, or the automation connection,” Morvan said.

Importantly, the redesign also simplifies upgrades.

“The new cell is a 100 percent drop-in replacement for existing IntelliChlor installations,” Morvan said.

Filtration Still Plays a Critical Role

Pleatco Technology Joins the Lineup

While sanitization keeps water safe, filtration removes the particles that cause water to appear cloudy. According to Morvan, the two systems must work in tandem to maintain consistent clarity.

“Sanitization and filtration really have to work together,” he said.

Pentair recently expanded its filtration lineup through the addition of Pleatco cartridge technology, which is now included in Pentair cartridge filters.

“Pleatco cartridges are now standard across Pentair’s cartridge filter lineup,” Morvan said.

Improved Flow and Debris Capture

Pleatco cartridges incorporate several design features intended to improve filtration efficiency. PurePleat technology keeps pleats evenly spaced, maintaining filtration surface area over time. Point-bonded filter media distributes debris capture across the entire cartridge surface, helping extend cleaning intervals.

Another design improvement focuses on water flow. Pleatco’s free-flow core maximizes the space water travels through, reducing pressure and improving overall system efficiency.

The Future of Pool Water Management

Moving Toward Predictive Care

Looking ahead, Morvan believes the pool industry is moving toward a more proactive approach to water management powered by connected technology and automation.

“The vision for predictive care is continuous monitoring of key parameters like pH, ORP, temperature, salinity, and flow,” Morvan said.

Sensors and automation systems can track those variables in real time, allowing the system to make small adjustments before conditions drift into problematic ranges.

“You’re not responding to cloudy water,” Morvan said. “You’re preventing the conditions that cause cloudy water.”

Automation also allows service professionals to monitor pools remotely and identify potential issues early.

“It’s almost like shifting from being a pool cleaner to being a water quality analyst,” Morvan said.

For Morvan, the goal remains simple: helping pool professionals deliver consistently great water.

“Water quality is not just a technical outcome,” Morvan said. “It’s an experience you deliver to your clients — and it’s the foundation of everything they think about your business.”
