The pool pumps are the most vital equipment to clean your swimming pool water.

I will definitely regard them as the heart of our pool water maintenance.

Without them, a swimming pool no longer remains sustainable and hygienic to swim.

The pool pumps generally consist of nine parts.

Those main parts are the impeller, the housing, the pump cap, the motor, the filter basket, the gasket, the diffuser, regulating valves, and the disposal plug or outlet.

The operating process of a pool pump is not that hard to understand.

They pull the dirty unfiltered water from your swimming pool.

The motor enables the impeller to rotate like a fan.

This rotating action pushes unfiltered water into the pool filter.

A pressure is developed which propels the movement of water through the filter.

The junk or impurities that are collected while filtration gets collected in the pool pump basket present in the housing.

The filtered water is then diverted back to the swimming pool through the main returns.

During this circulation process, the pool chemical gets mixed homogeneously.

The pool water thus becomes safe for our swimming.

In the market, you will find three types of pool pumps.

First is single-speed pool pump, second is a dual-speed pool pump, and the third type is a variable-speed pool pump.

The single-speed pool pump as the name suggests, can operate at only one single speed.

This type of pool pump is not expensive but consumes more power to operate and can be very expensive in the long run.

The dual-speed pool pump, on the other hand, can operate at two different speeds namely high speed and low speed.

Due to their adjustable speed limit, power consumption is much lesser than the power consumption of single-speed pumps.

The third type of variable speed pool pumps have multiple speed limits.

Generally, they are equipped with 3 to 8 pre-programmed speed limits.

They can also operate perfectly at a lower speed limit for a long time without much issues.

Thus, as per my experience, these pool pumps are most cost effective and are a great energy saver too.

You can easily set the speed limit of these pumps as per your requirements.

Although they are costlier than the other two types of pool pumps, they offer great benefits in the long run.

They can run 24*7 and thus ensure better water circulation in the swimming pool.

As mentioned earlier, pressure is created during the rotating action of the impeller of the pool pump.

This pressure controls the water circulation throughout the pool.

Thus, for optimum water circulation, this pressure value should not be too high or too low.

Usually, the value of your pool pump pressure varies between 10 to 25 PSI.

So, any deviation from this range should be considered not normal.

It indicates that something is wrong in your pool pump system.

The normal pool pump pressure value is different for every pool.

It depends on several factors like the size of your swimming pool, the size of the pump, the cleanliness of the pool filters, etc.

The best time to determine the baseline value of pool pressure is when the filter is newly installed or after the backwashing process.

The value obtained can be considered as a reference for the future.

So, when your pool pressure gauge reads 35 PSI, it indicates that the machine is under high-pressure conditions.

It also tells that some error has occurred which has caused this situation.

Now, one of the main reasons for the occurrence of high-pressure conditions in pool pumps is dirty and clogged pool filters.

In addition to this, there are a few conditions that may cause high pressure at the pool pump.

I will first explain three main reasons that are responsible for higher pressure in your pool pump.

After that, I will provide 5 important solutions to fix this high pressure problem of the pool pump which tends to go beyond 35 psi in some conditions.

Why You Need to Avoid High Pool Pump Pressure?

High pool pump pressure is not something that can be taken lightly.

When the pump is running under high-pressure conditions, it may rupture exerting great force.

This explosion of the machine can seriously injure the users.

So, while operating the device, always keep an eye on the pressure gauge.

If it displays a higher-than-normal value, turn off the machine immediately.

Then look for the causes of this high pressure problem and try to solve it using the solutions that I have provided in this article ahead.

3 Main Reasons that Cause High Pressure in the Pool Pump

Reason 1: High pressure is created when the pool pump starts to push water at a higher flow rate than the actual capacity of the pool filter that can efficiently handle.

Reason 2: The blocked filter creates a narrow passage of water.

This creates back pressure inside the pool filter.

Reason 3: When a suction air leaks at the pump, it creates an air pocket inside the pool filter.

This leads to the creation of back pressure.

5 Easy Solutions to Fix High Pressure Problem of a Pool Pump

If your pool pump’s pressure gauge is displaying a high value, then I recommend you to try my following 5 tips to solve the issue asap.

Solution 1: Clogged Pool Pump Filters

One of the main reasons for the creation of a high pressure at pool pumps is its dirty and clogged filters.

Once you find that the filters are clogged with debris, then you must clean those filters asap.

In the case of sand and DE filters, regular backwashing would be sufficient.

But for cartridge filters, you have to manually clean the cartridges after removing them from the filter assembly.

Solution 2: Compare and Control the Flow Rate

Every filter has a specific flow rate that it can handle efficiently.

If the capacity of the pump is more than required, then it will draw in more water.

After that, it will easily surpass the flow rate of the filter causing back pressure.

To prevent this from happening, you need to first compare the horsepower and flow rate of the pump with the flow rate of the filter.

If the size is not appropriate, you need to replace it.

For the variable speed pool pumps, you can still use them by running them at a lower speed limit.

Solution 3: Use Good Quality Filtering Media

For sand and DE filters, the filtering media play a crucial role in the filtration process.

To avoid the creation of high pressure, always use an appropriate quantity and good-quality of filtering media.

Solution 4: Use Only the Right Sized Water Jets

If you have a vs pool pump then I highly recommend to use the proper size of water jets.

It should not be too big or too small.

The smaller water jets constrict the path of water flow.

Hence the flow of water gets hindered and pressure is created in the process.

To avoid this, replace the narrow water jets with the appropriate size.

The water can then flow smoothly and high pressure will also be gradually drop down.

Solution 5: Keep Breather Tube Clean and Clutter Free

Regularly check the breather tube for any blockage.

The breather tube is responsible for releasing any unwanted air from the top of the filter assembly.

If the tube gets blocked, the excess air will get trapped and pool pressure will rise.

Therefore, I always recommend to first checking and cleaning the breather tube regularly.

Remove the impurities by washing them thoroughly with a hose.

But to do this you must always switch off the pool pump first.
