A low pool water pressure can lead to various problems: cloudy water, algae growth, and fountains or bubblers with weak water flows. Besides turning your pool into an eyesore, these issues can have an impact on the water’s safety and comfort.
If you suspect that your pool has low water pressure, you can confirm it by checking the filter gauge. Most filter systems are designed to operate in the 5-15 or 10-20 pounds per square inch (PSI) range, depending on the size of your pool and your pump. A pressure reading that’s at least five points below or above the recommended level can cause low water pressure.
Once you confirm that your filter’s pressure is off, you need to identify and address the cause to bring your pool back to normal. Clark County Pool and Lawn, a trusted swimming pool cleaning service in Las Vegas, shares the common causes of low pool filter pressure and how to fix them.
1. Dirty filter
Dirt buildup makes it difficult for water to pass through your filter. This weakens the pool’s water flow. If the pressure reading is higher than the standard level, then that means it’s time to clean your filter.
For cartridge pool filters, you can clean them simply by taking out the cartridge then spraying it down with a garden hose. Make sure to wash between the pleats to get rid of all the gunk and debris. You can use a filter cleaner product for stubborn dirt.
Remember to clean your cartridge filter at least every six weeks to prevent dirt from building up and causing various pool problems.

2. Clogged skimmer and strainer basket
Just like with your pool filter, clogged skimmer and strainer baskets restrict the water flow to the pump, leading to a low water pressure. So, keep your skimmer and strainer baskets free of debris to keep the water flowing freely throughout the pool.
To clean them, you only need to remove the lid then empty the basket of leaves, twigs, and other gunk. Rinse out the basket with a garden hose to get rid of the sticky grime and dirt. You also want to check both baskets for cracks, tears, or other kinds of damage. If you find any, that means it’s time for a replacement.
3. Suction leaks
A leak on the suction side of your pump can cause various problems. Small leaks can suck in air through the pump and collect at the top of the filter tank. This air buildup can create enough opposing pressure that the water flow is pushed back, causing a drop in water pressure.
If the suction leak has grown too big, it will siphon too much air into the system, causing the pump to lose its prime.
One easy way to detect suction leaks is by using a bucket of soapy water. Smear bubbles over the pump system while it’s running. If you see any bubbles getting sucked in, that means you have a leak. Call a pool pump repair expert immediately to have the leaks patched up.
