Filter Valves

Are you looking to keep your pool or spa water crystal clear? You're in the right place! Here, we talk all about pool filter valves. Whether you have a swimming pool sand filter valve, an above-ground pool filter valve, a pool filter pressure relief valve, or a Hayward pool filter valve, we'll guide you through their functions and types and explain how to maintain them. 

Clean water is key for a great swimming experience, and it all starts with the right filter valve. Let's make pool care easy together.

Importance of Filter Valves

Filter valves are important for keeping your pool water clean and safe. Think of them as the helpers that ensure only clean water gets into your pool. 

They work with your pool's cleaning system to remove all the dirt and stuff you don't want in the water. This way, your pool stays a fun and safe place for everyone. 

Whether you have a sand filter valve for your swimming pool, a valve for an above-ground pool, a pressure relief valve, or a Hayward brand valve, they all do this important job. So, keeping them working right helps keep your pool water just right for swimming.

Types of Filter Valves

Swimming pool filter valves are crucial in maintaining the water's cleanliness and clarity. These valves control water flow through the pool's filtration system, including sand, cartridge, or diatomaceous earth (DE) filters. Here's a brief overview of the common types of filter valves and their functions:

  1. Multiport Valve

This is a popular type of valve seen in many pools, especially those with sand or DE (a type of powder) filters. 

It has several options like filter (to clean water), backwash (to clean the filter by flipping the water flow), rinse (to make sure the filter is clean after backwashing), waste (to get rid of water without filtering it), recirculate (to move water around without filtering), and closed (to stop all water flow). 

This makes taking care of your pool flexible and straightforward without messing with the pump or filter too much.

  1. Push-Pull Valve (Slide Valve)

This valve is easier to use but doesn't do as many things as the multiport valve. It has two main settings: Filter (to clean the water) and Backwash (to clean out the filter). It's a good choice for DE filters and helps keep things simple if you don't need all the features of a multiport valve.

  1. Top Mount Valve

This valve is on top of the filter, usually in smaller or above-ground pools. They're part of sand filter systems and are great because they don't take up much space. They're designed to be part of the filter unit, making setup and maintenance easier for smaller pool setups.

  1. Side Mount Valve 

These valves are attached to the side of the filter and are often seen in bigger, in-ground pools. They can handle more water flowing through them, which means they're great for larger pools. Having the valve on the side makes it easier to take care of the filter when it needs cleaning or maintenance.

  1. Automatic Valves

Some pools have high-tech valves that do the work for you. They automatically change the water flow based on what the pool needs. This means less manual work because the system decides when to filter, clean the filter, or circulate the water. It's like having a smart helper to manage your pool's cleanliness.

How to Choose the Right Filter Valve?

Choosing the right filter valve for your pool doesn't have to be complicated. Here's how you can pick the perfect one:

  1. Know Your Pool Type: First, look at what kind of pool you have. Is it above ground or in-ground? The size and type of your pool can guide you toward the right valve. For example, above-ground pool filter valves are often designed to be more compact and easy to install.

  2. Understand Filter Types: Different filters work best with certain valves. If you have a sand filter, you'll likely need a multiport valve because it offers the flexibility sand filters require. For DE filters, a push-pull valve might be enough, though many prefer the versatility of a multiport valve.

  3. Consider Maintenance: Consider how much time you'reyou will spend on maintenance. Multiport valves offer more options, making pool care easier and a bit more complex. If simplicity is your goal, a push-pull valve might be the way.

  4. Look at Flow Rate: Larger pools need valves that can handle more water. Side mount valves are great for in-ground pools because they support higher flow rates. Smaller or above-ground pools can usually get by with top-mount valves.

  5. Automation Preferences: If you want to make pool maintenance as easy as possible, look into automatic valves. These can adjust the flow based on your pool's needs, cutting down on manual adjustments.

  6. Expert Advice: If you're still unsure, asking an expert can help. With years of experience, professionals can offer advice tailored to your pool's needs.

Maintenance Tips

Keeping your pool's filter valves in top shape is key to clean water. Here's how to do it:

  • Regular Backwashing: This is like cleaning your filter from the inside out. It helps get rid of all the dirt and stuff the filter catches. Doing this often keeps your filter working well and lasting longer.

  • Leak Inspection: Look at your filter valves and around your pool for any leaks. Catching a leak early can save water and prevent bigger problems.

  • Component Replacement: Watch out for signs of wear on your filter and its parts. If something looks old or worn out, replacing it before it breaks can save you a lot of trouble.


Understanding and caring for your pool filter valves is essential for a crystal-clear pool. Whether you're dealing with swimming pool sand filter valves, above-ground pool filter valves, pool filter pressure relief valves, or Hayward pool filter valves, proper selection and maintenance are key. 

Regular backwashing, observant leak inspections, and timely component replacements will ensure your filtration system functions flawlessly. 

A well-maintained filter valve keeps your pool water clean and extends the lifespan of your pool's filtration system. Embrace these tips and enjoy a pristine pool that beckons you for a refreshing dip anytime.

Frequently Asked Questions

What Is the Difference Between Above-Ground Pool Filter Valves and In-Ground Pool Filter Valves?

Above-ground pool filter valves are typically designed for easier installation and maintenance and are suitable for the compact systems of above-ground pools. In contrast, in-ground pool valves often handle higher flow rates and offer more settings for detailed pool management.

How Often Should I Backwash My Swimming Pool Sand Filter Valve?

You should backwash your swimming pool sand filter valve whenever the pressure gauge reads 8-10 PSI above normal, which usually translates to every few weeks during heavy use or after a large debris event.

Can Pool Filter Pressure Relief Valves Affect Water Clarity?

Yes, pool filter pressure relief valves are crucial in maintaining optimal pressure within your filter system, ensuring it functions efficiently to remove impurities and keep your water crystal clear.

What Makes Hayward Pool Filter Valves Different?

Hayward pool filter valves are known for their durability, reliability, and ease of use, making them popular among pool owners for maintaining water quality and clarity.

When Should I Replace My Pool Filter Valve?

Replace your pool filter valve if you notice consistent issues like leaks, difficulty in switching modes, or if the valve fails to maintain proper water flow and pressure, indicating wear or damage.
