  • Product Details

A properly functioning pool filter air relief valve is vital to the performance of your pool’s circulation system. The filter will keep the debris from building up in your pool if the pool pump filter is functioning properly. It is important to ensure that the air relief valve works perfectly as this will keep the circulation of the pool pump. It plays an important role in the water's chemical balance and this is why you should ensure that it works properly. It is important to know how to use the air relief valve whenever necessary. In this guide, we will provide all the details regarding the Poolking's pool filter air relief valve.

What Is an Air Relief Valve? 

An air relief valve works alongside the pressure gauge. Air builds up inside the filter tank and this could create a problem for the pool pump to run properly. Upon start-up, opening the air relief will provide a vent for trapped air.

When the pump starts, the water starts to rush through the system. If trapped air is not released, then it can be compressed by this flow of water. This helps with increasing the pressure and can affect the pool equipment. It also causes the top of the filter or the pump lid to blow out.

The trapped air competes with water for space inside the tank and can prevent the water from flowing all through the full filtration area. It can reduce the filter’s efficiency and can damage the pool pump as well. There are many reasons why the air can get into the system. There can be different scenarios that require releasing it through the air relief valve.  

Some of the possible causes for the gathered air is the opening of the pump lid for a long time. It is important to prime the pump and cleans the strainer. You should keep the pool pump in the best condition by backwashing, and vacuuming it with a cracked hose.

What Is the Function of a Pool Filter Air Relief Valve? 

The pool filter pressure gauge must keep the pressure levels steady and this can be done successfully with the help of an air relief valve. The gauge may indicate high pressure because the air in the circulation system might have increased. This could happen if the pool water level is too low. It should be situated at the midpoint of the skimmer.

If you have turned the pool off for a long time because it is time for you to clean it then this could create some issues with the filter pressure gauge. When you start things back up, you might discover that there is some air in the system.

When water begins to flow through the system, it will complete the air for space. It forces the air through the system. If the pressure gauge is left without use for long, then it can damage your equipment. The pump must contain water to function properly.

When you use the pool filter air relief valve to release the air from the system then the water will once again fill the plumbing the way it should be. The equipment will be safe, and you will also be able to protect the pool filter pressure gauge before it goes back down.

Both the filter pressure gauge and the air relief valve are important to the overall health of your pool’s filtration systems. It is important to maintain your pool in a good shape and you can do so with the help of a premium quality pool filter.

Signs Your Air Relief Valve Is Damaged 

When the pump has been turned off, air can build up inside the tank. If your filter tank is filled with air, then this can cause a build-up of pressure. When the system is turned on and the water begins to flow into the tank it can lead to excessive pressure. This causes the pump lid or filter top to blow out which can lead to potential damage to the swimming pool equipment. This can also affect the ability of the water to flow through the entire filtration system.

When you open the pool filter air relief valve on your filter a lot of air comes out of it. By turning on the pump the air continues to rush out for another 10 seconds but then in a few seconds, the water starts spouting out. The filter stays at very low pressure which could be a sign that your air relief filter is not working properly.

You will get a build-up of air from somewhere inside the system. A suction side leak or the water level will be too low and sucks in the air at the skimmer. If your pump basket frequently has air bubbles and never looks full then your air relief valve might have some issues.

When the pump is off and you open the air release valve the water can start to drain out of the filter and suck air in. This is when you should get the pool filter relief valve fixed. The real check can be to open the valve after the pump has run off for a while. This will help you to see if the air has been accumulating in the filter.

How to Fix Your Pool Filter Air Relief Valve? 

If your pool filter air relief valve has not been functioning well then it is best to fix it. Here are the steps that you need to follow to fix your pool filter air relief valve.

 · Turn on the pump and check that the RPM is running normally.

 · Once the pump has run for 3-4 min, this means that it has primed completely.

 · Leave the filter valve open until you see water coming out. Close the valve and let the water run for 15-30 secs. Open the valve until it starts hissing again or until the water starts to come out again.

 · Turn the pump back on and let it run for more than 10 minutes. If you see no air, then that means that the pool filter air relief valve is working properly.
