Why is my Pool Pump Losing Pressure?- Know the potential causes

Why is my Pool Pump Losing PressureSwimming in the fresh, blue water on a hot summer day is like a blessing. So you will naturally worry if the pool pump (the heart of your pool) starts behaving abnormally.

You have surely faced some difficulties with your swimming pool and have asked yourself why my pool pump is losing pressure. It’s okay, you will ask, we will answer.

So, stay with us. We will try to help you the most. Let’s get into it!

The potential causes of your pool pump’s pressure loss

There are several reasons to happen so. Take a glance over these:

1. Lacking knowledge about gauge pressure

It’s not possible to be a jack of all trades. But it’s crucial to know the basics of gauge pressure. This device is a calibrated round device that is positioned on the upper side of the filter.

The main job of this device is to record the pressure and accumulate inside the filter. Gauge pressure is generally graded with figures 0-60 and often breaks into tick marks or 5’s or 10’s. Doesn’t it make sense?

Well, it actually measures the water force flowing in the system in psi (pounds per square inch).

If you identify and record the normal operating force at the beginning of the installation, you’ll notice easily when the gauge force deviates from the normal one.

2. Congested skimmer basket and strainer basket

Unwanted air in the system is a cause of losing pressure. A congested skimmer basket or strainer basket can create pores in the pipelines which will result in sucking air in the system.

The pieces of trash or any debris will be your future agony. So, try to clean them regularly and let the whole system stay clean.

3. A clogged filter

Checking out and cleaning the filter regularly is probably the easiest remedy.

A clogged filter will allow a very low amount of water to go through it which will reduce the pressure inside the pool pump. You have to replace it whenever needed.

4. A jammed impeller

The impeller, a very crucial component for your pool, rotates to create suction power. Debris like small pebbles or anything else is enough to block it from rotating.

Another point to be noted, your impeller must be right-sized. If it’s undersized, it’s simply underworked. So, your duty is to know when to clean the impeller and use a correct sized impeller.

5. Annoying air leaks

This is the most troublesome reason for pressure loss. The pipelines work without air, so it’s very unwanted to enter the air in the system. This air will create bubbles and will impede the pump’s capability to create pressure. So, you have to replace or repair the pipe if there’s any leak.

How to be sure whether there’s any leak or not? For a few moments, the water will shoot out of any leak. So, turn off the pump and check out the above-ground piping.

6. A damaged motor

A damaged motor will not supply your pump with a perfect amount of pressure. You will see, you’re trying to start the motor but it’s failing to work.

In this case, you’re a faulty, ill-working motor owner. So, replace it as soon as possible.

So, these are the most common reasons for having a lost-pressure pool pump. In addition, you should have an idea about when your pool pump loses pressure.


Our discussion has reached the furthest point. We hope that you could collect enough information from this article which will help you to troubleshoot.

So, is it still greek to you that why my pool pump losing pressure? It’s definitely no! Your pool pump is dedicated to serving the whole swimming pool. So, it’s kind to troubleshoot and take care of it.
