A pool filter pressure gauge air relief valve is a component that helps in improving water circulation in the pool and keeps an eye out on the overall health of your pool.

There are no electrical parts and it runs on pressure. This measuring device on top of your filter tank let’s you know the amount of pressure inside your tank, and figures out if the water is flowing normally or not. This is important because the pressure is responsible for running the whole process of cleaning the pool water.

There is also an air relief valve attached that helps in releasing any trapped air in the filter system. It is bad for your pool if air gets trapped inside the filter system because pressure could increase and disturb the flow of water, hence it is vital that you keep your pressure readings within normal range by getting rid of trapped air using an air relief valve.

A pool filter’s job is to keep your pool free from debris and dirt while a gauge lets you know if there are any problems in the pool valves or lines such as a clog or a leak. This can indicate that there’s a problem when it’s time to clean your filter.

Different filter systems run on different readings depending upon the pool size and this is why it is vital to know how to read and use your gauge and release valve properly.

How Are These Offers Used?

A pressure gauge is a device that lets you read the pressure and know if it’s low, normal or excessive. A “low” reading will generally mean that there is a problem in the flow of water and something might be blocking a normal flow.

Indication of “high” on the gauge indicates a flow problem due to a dirty pool. If your gauge is spiking up to 40 or 50 psi then shut off the pump immediately and look for what is causing the problem.

This could be due to several reasons such as a faulty equipment or too much dirt in the pool. You might have to replace the cartridge and clean the filter to get the job done. A normal reading means that water flow is normal and everything within your pool is fine. However, there’s no normal standard reading as the right figure depends on the size of the pool. Reading a gauge is easy. You simply read where the needle is pointing at and that’s generally your reading.


It is vital that you get a reliable choice for your pool if you want to keep it in a good shape. The need for this tool is simple. This relief valve is common for air to gets trapped into the filter system which may cause disturbances in the pool and make the filter malfunction. The result is a debris-covered pool.

An air valve lets you release trapped air and the gauge keeps you updated about the building intensity inside the filter system.
