Swimming Pool Valves 101

Other Valves You Might Come Across

There are a few other pool valves worth knowing about. If you’re working with a sand filter, you’ve probably seen a sand filter valve. These come in multiport or push-pull styles and are used to switch between filtering, backwashing and rinsing modes. If your filter has a pressure gauge, it probably also has an air relief valve. And if your pool uses an automatic water leveler, there’s usually a float valve involved. Knowing how to adjust a pool float valve can help keep your water levels just right without wasting water.

When to Replace a Pool Valve

Pool valves are built to be tough, but sadly they don’t last forever. Over time, exposure to sun, chemicals and constant use can wear them down. If you’re noticing any of the following issues, it’s probably time to start thinking about a pool valve replacement.

• The valve is leaking, especially around the handle or fittings

• It’s getting harder to turn, or it feels stuck in certain positions

• The handle is cracked or broken

• You see visible damage, like cracks in the valve housing

• Water is flowing when it shouldn’t—or not flowing when it should

Sometimes the issue is something simple, like a worn-out gasket or o-ring, which you might be able to replace without swapping the entire valve. But if the internal seals are shot or the valve body is cracked, it’s usually better (and safer) to go ahead and replace the whole thing.

If you're dealing with a pool valve replacement for a filter, make sure you choose the right style, like a multiport valve for a sand filter or the proper diverter valve for your plumbing setup. And when in doubt, stick with quality brands like Jandy, Hayward or Pentair so you're not back in the same spot next season.

Brand Spotlights: What You Should Know

When it comes to choosing the right pool valve, sticking with a trusted brand makes your life a lot easier. Three of the most reliable names in the industry are Jandy, Hayward and Pentair. These brands have been around for decades, and there’s a reason most pool pros reach for them.

• Jandy pool valves are known for their smooth operation, durable construction and tight seals. They’re especially popular for pool/spa combos and setups that involve automation, like controlling water features or switching between heating options. Jandy’s three-way diverter valves are a go-to for a lot of modern pools.

• Hayward valves are another solid pick. They offer everything from simple ball valves to multiport sand filter valves, and their gear-driven actuators work great with pool automation systems. Hayward parts are also easy to find, which is a big plus when it’s time for a quick repair.

• And then there’s Pentair valves. They’re high-quality, easy to service and compatible with a lot of different pool systems. Pentair offers both manual and motorized valves that hold up well under pressure. So, it can handle the situation no matter if you're managing a standard chlorine setup or something more complex.

Whichever brand you choose, going with a name like Jandy, Hayward or Pentair helps ensure that your valves perform well, parts are available when you need them, and everything plays nicely with your existing system.

Tips for Adjusting and Opening Pool Valves

No matter if you're opening your pool for the season or just trying to get water flowing to the right places, knowing how to adjust your pool valves properly makes a big difference. It might look a little intimidating at first, but once you know what each valve controls, it's actually pretty straightforward.

To open your pool valves for startup, begin by making sure all necessary valves are in the open position. This usually includes the suction side (pulling water from the skimmer and main drain) and the return side (sending water back into the pool). Most valves will have a handle you can turn. Line the handle up with the pipe to open it; turn it perpendicular to close. If you’re not sure what’s what, start by opening everything, then make adjustments once your system is running smoothly.

One of the best things you can do is label your valves with a permanent marker or a bit of waterproof tape. Write things like “to spa,” “from skimmer,” or “to heater” so you’re not guessing every time. It saves time and prevents accidents.

And here’s an important tip: always turn off the pump before adjusting your pool valves. This is because changing valve positions while the pump is running can create pressure problems and even damage your system. Once everything’s in place, restart the pump and check that water’s flowing where it should.

You don’t have to be a pool expert to keep things running smoothly, but understanding your swimming pool valves goes a long way. From redirecting water to protecting your equipment, every valve in your setup plays an important role. So whether you're adding a new water feature, managing a spa spillover or shopping for a pool valve replacement filter, the right valve really does make all the difference.
