Why Pool Filter Pressure Gauge Not Working?

Did you plan to enjoy a relaxing swim in your pool and realize the pool filter pressure gauge not working?

Anyone who has a pool may probably come across this problem at least once in their life, so don’t worry!

Seeing the pressure gauge show zero pressure can be worrisome. However, to understand the reason for a malfunction and Hayward pressure gauge troubleshooting, it’s important to know about the pressure gauge and its function.

What is a pool filter pressure gauge?

The pool filter gauge is the visual representation of the pressure inside the tank, measured in PSI (pounds per square inch). The gauge works properly if the water flow in the system is normal. Yet, in the case of disturbed water flow, the pressure fluctuates and is indicated by the gauge. If the pool filter pressure gauge is stuck due to one reason or the other, there is no other way to monitor the pressure inside the pool.

Pool filter pressure gauge not reading

A broken or nonfunctional pressure gauge may be represented by various readings like showing a low reading, showing high pressure, or the pool filter pressure gauge not reading at all.

Let’s see what causes each of these and how you can fix the issue.

Low Pool Pressure

Any of the elements before the pump or the pump itself cause a low pool pressure. To resolve the issue of low pool pressure, check the skimmer basket and the pump impeller to find the cause. Remove any debris if found, or look for leaks. While you can easily clean the strainer basket yourself, you will need a professional to fix the leak or damaged part of the system. Risen pressure on the gauge after troubleshooting shows that the gauge is working perfectly fine.

High Pool Pressure

A high pool pressure is typically caused as a result of a dirty pool filter. Either it’s clogged with dirt or some part has broken internally, blocking the filter. While restarting the filter, make sure to keep an eye on the filter. Rising pressure above 30 PSI can lead to an explosion. Shut down the filter system and contact a professional to sort out the issue. Pool pump pressure gauge high when off could be the sign of a broken gauge.

No Pressure

While it is absolutely healthy for the pool pressure gauge to not show pressure when shut off, if the pool filter pressure gauge reads 0 while operating, it indicates a problem. It could be due to one of three reasons mentioned below with their potential solutions.

If the water is flowing through the pump at a normal rate, the pressure falls maybe because of air bleeder assembly obstruction. To eliminate dirt, take out the pressure gauge and check the air bleeder assembly.

Another possible cause of pool filter pressure gauge needle stuck is blockage before the pool filter. It does not affect the water is often unidentified. Check the pump basket, suction line, valve, and impeller to resolve the issue.

If none of these two seem to be the reason for the pool filter pressure gauge not working, it may have a broken needle. Use your finger to lift the needle. If the needle bounces back, the gauge is broken.

Pool pressure gauge is not a very expensive part of the system, and you can conveniently get it replaced at the earliest.

What should the pool filter pressure gauge read?

Pool filters are an essential part of maintaining your swimming pool. They remove debris such as leaves, sticks, bugs, etc. from the water. If you want to keep your pool clean and healthy, then you should check the pool filter pressure gauge regularly. It is recommended that you check the pool filter pressure gauge every week.

However, there are different types of pool filters and their pressure gauges vary. Some pool filters use a spring-loaded pressure gauge while others use a float-based pressure gauge. The pressure gauge reading depends on the type of pool filter you have installed. In this article, we will discuss the different types of pool filters and their pressure gauges.

Looking for an ideal pressure gauge reading compared to other people’s pools is not a good idea as each gauge is built differently, and the ideal reading may vary from another. Some pool pressure gauges are perfect at 5 to 10 PSI, while others showing 10 to 20 PSI have the right pressure. If you are willing to find out the specific ideal for your pool’s gauge, note the value when you use the filter for the first time or just after cleaning.

If you’re using chlorine for disinfecting the water, the reading on the pool filter should be between 1.5 and 2.0 pounds per square inch (psi). If you’re using bromine or ozone, the reading should be between 0.8 and 1.2 psi.

Why is the pool filter pressure gauge reading 0?

I had a problem with my pool pump and needed to replace it. After replacing the pump, I noticed that the water level was low and the pump wasn’t working properly. The next day, I checked the pool filter and found out that the pressure was at zero.

After checking the manual, I realized that the pressure should be between 5 and 10 psi. It turns out that the pressure was at zero because the filter was clogged.

So, if you find yourself with a similar issue, check the manual first before calling a plumber.

What to do for pool pump pressure gauge leaking?

Leaking pressure gauges are not a common sight, yet if you are experiencing one, it may be due to a leak in the air relief assembly. The leak can be prevented by fixing the air relief assembly before more damage occurs.

Final Words

The pool filter pressure gauge not working properly can worry you. Yet, it is worth knowing if the problem lies within the pressure gauge only; you can easily replace it. Any further issues in the system need professional evaluation to find an adequate solution before it proves to be detrimental to the pool system.
