When a Pool Pump Loses Pressure? – Get your Answer

When a Pool Pump Loses PressureYour pool pump, the heart of your pool, sometimes shows weak or abnormal behavior. Losing pressure is one of the abnormalities.

It indicates you actually have weak jets and a low PSI reading on the filter’s pressure gauge. So, you should have knowledge about the pressure gauge and its job.

We are here, as a helping hand, for answering you when a pool pump loses pressure. So, don’t overthink, stay with us.

See yourself what’s there for you!

What is the normal pressure range of your pool pump?

As you have searched on google, you may have noticed something unusual about your pool pump.

You probably know, a calibrated round device called ‘pressure gauge’ located on the upper side of your filter. This device measures the pressure of your pool pump.

The general range is 10-25 PSI (pounds per square inch). You should identify and record the usual operating force from the beginning of the installation.

It will help you to notice when the gauge force deviates from the normal ones. So, you have to look after the operation of your pressure gauge regularly.

When you can be sure that your pool pump is losing pressure?

There are some signs you can easily notice and be sure that your pump is losing pressure.

When the water level is low

If the water level is too low, the pump will face trouble while priming the water pressure will be dropped. At least, the water level should be halfway up the skimmer’s opening.

When the skimmer basket is clogged

When your skimmer basket is full of dirt and debris, the pipe will be shut off between the skimmer and the pump. This will naturally reduce the flow of water to the pump.

If the entering and outgoing water being less, this means your pump is doing less work.

To get rid of it, remove all the debris and keep clean your skimmer basket.

When your strainer basket is clogged

This is the same case as the above-mentioned one. For a clogged strainer basket, there will be less water flow which results in less water pressure.

Same as the above, remove the debris and keep it clean.

When the filter is jammed

If you have a jammed filter, water can’t get through this. Thus, you will have less water flow out of the filter.
Wash your filter and make sure it never stays stuck with dirt and debris.

When you have a clogged impeller

When your impeller is clogged with debris, the water can’t rotate out the sides of the impeller. This reduces suction which reduces water flow through the pump.

Keep the impeller clean so that it can’t turn into a clogged one. Grow your idea about when to clean the impeller.

When your pump has a suction leak

Last but not the least, a suction leak plays a huge role to lose the pool pump pressure. When the leak is large enough, too much air will suck into the system. As a result, the pump will lose prime.

So, find the suction leaks and close them. The pipelines work without air, so let them work properly.

So, these are the common visible signs that you can notice and actionable steps. A pool pump circulates the water, so it’s very important to maintain the pump properly.


Your heart circulates blood to the body and the pump circulates water to the pump. Aren’t they similarly important?

As a pool owner, it’s your duty to maintain your pool pump and let it be safe from every unwanted situation.

So now, you have got your answer that when a pool pump loses pressure, right? Try to fix it as soon as possible and have a happy pool pump again. Good luck!
