Get to Know Your Pool Valves: The Essentials for Efficient Pool Maintenance

When it comes to pool maintenance, understanding your pool’s plumbing system is key. Your pool’s water flows through a well-designed circulation system, which moves it from the pool through the pump and filter, past the heater, and back to the pool. This system keeps your pool clean and your water swimmable. However, when you need to divert water or control the flow direction, pool valves come into play.

In this guide, we’ll dive into the types of pool valves, how they work, and why they are crucial for maintaining your pool’s efficiency and water quality.

What are Pool Valves?

Pool valves are integral parts of your pool’s plumbing system that control the direction of water flow. Without valves, water could flow backward through the filter, heater, or other equipment, reintroducing dirt, debris, and bacteria back into the pool. Pool valves are essential for ensuring water flows in the right direction, protecting your equipment and ensuring your pool water stays clean and safe.

Types of Pool Valves

Several types of pool valves help regulate water flow in and out of your pool. Below are the most common types you’ll find in your pool's plumbing system.

1. Multiport Valves

The multiport valve is typically found on the pool filter and is used for controlling the flow of water in different directions. It enables you to direct water through the filter to clean it, rinse or backwash the filter, or expel water to waste. This valve is also useful when you need to perform maintenance tasks like vacuuming the pool or clearing the lines when opening the pool for the season. Some models even feature a winter setting that helps prevent freezing damage to your pipes.

2. Diverter Pool Valves

Diverter valves allow you to redirect the water flow from one part of the plumbing system to another. There are two main types of diverter valves:

• 2-way valves: These valves control the flow to or from just one port. They can be fully opened, closed, or partially opened depending on your needs.

• 3-way valves: These valves have three ports, which allow you to control the flow between two end ports. For example, you can adjust the water flow to the skimmer or drain while keeping the center port open for other purposes. These valves are commonly used in larger systems or pools with more complex plumbing.

Both types of diverter valves are available with or without unions, which makes it easier to repair or replace them without cutting them from the plumbing.

3. Check Valves

Check valves prevent water from flowing backward when the pump is turned off. These valves are essential in several situations to protect your pool equipment and ensure water does not flow back into the pool:

• Chlorinators: If you use an automatic chlorinator or a salt chlorine generator, a check valve is necessary to prevent concentrated chlorine from flowing backward into your filter or heater when the pump shuts off.

• Hot Tubs: If your pool is connected to a spa, a check valve ensures that water doesn’t flow from the spa into the pool, which could upset the water chemistry in both areas.

• Water Features: If you have fountains or other water features, a check valve prevents water from draining back into the pool when the feature is turned off.

• Solar Heating: If your pool uses a solar heating system, a check valve is essential in the pipe that leads to the solar panels. It prevents water from flowing backward due to gravity when the pump is turned off, ensuring that the solar panels remain filled with water to capture heat.

4. Valve Actuators

Valve actuators are part of pool automation systems. They allow you to control the diverter valves remotely, making it easier to manage the flow of water to different parts of your pool system. By wiring these actuators to your pool's control box, you can push a button to adjust the flow of water, turn on water features, or activate your hot tub—all without manually adjusting the valves.

Why Pool Valves Are Crucial for Pool Maintenance

Pool valves are a small but vital part of your pool’s plumbing system. They ensure water moves in the correct direction, maintaining proper filtration, preventing backflow, and protecting your equipment from damage. Regular maintenance and timely valve replacements will keep your system functioning efficiently, saving you from costly repairs and ensuring clean, safe pool water year-round.

How to Replace Pool Valves

Like any pool equipment, valves wear out over time. Pool valves can last for many years, but eventually, they may need repair or replacement. If your pool system is from the pre-1980s, consider updating your valves, as newer models are designed to be more efficient and durable.

Replacing a diverter valve or any other valve can often be done without calling a professional if you have the right tools and know-how. However, if you’re unsure, it’s always best to consult a pool technician to ensure everything is working properly.

Conclusion

Understanding the different types of pool valves and their functions is key to keeping your pool system running smoothly. Whether you're cleaning your filter, controlling water flow to various parts of your pool, or preventing backflow, valves play a crucial role in protecting your equipment and ensuring optimal water quality. By maintaining your valves and replacing them when necessary, you can avoid costly damage and enjoy a well-maintained, efficient pool all year long.
