What causes low pressure in a sand filter?
A clogged pipe from the skimmer, suction line or main drain reduces the amount of water to the pump which can reduce water flow to the pump and create low water pressure out the return lines. Push a stiff wire down the skimmer or suction ports to see if you have a clog near the entrance.
What should the pressure be on my sand filter?
If anything could be considered “normal”, it would be about 10 psi. Most filter systems are designed to operate in the 5-15 or 10-20 psi range. The way to find out your particular correct pool filter pressure is to clean or backwash the filter thoroughly and empty the pump and skimmer baskets.
Why is the pressure on my sand filter so high?
A filter that’s too small for the pump can cause a build-up of pressure inside the tank. This is due to the fact that the pump is pushing more water through than the tank can handle. The pressure could also be high due to a dirty filter that needs to be rinsed. However, low pressure is also an issue.
Why does my pool have low filter pressure?
It’s never a problem after the pool pump, because after the impeller, the pool water is under pressure, and obstructions result in higher than normal pressure. Here’s a list of common causes of low filter pressure. Pool cleaner not moving around the pool well or may have stopped altogether; Reduced water movement in the pool
Is there a problem with the sand filter in my swimming pool?
Troubleshooting a swimming pool sand filter, unlike a torn pleat in a cartridge filter or a torn grid in a DE pool filter, might be hard to find. If the pool filter media is bad or there’s a broken lateral, you can’t know simply by opening the lid on the swimming pool sand filter and looking inside.
When do you use the filter position setting?
This setting is used to filter the water through the sand. It is the pool filter valve positions setting that your filter will spend most of its life on. Mostly it will be used when the pool pump runs on your timer to keep the water in the pool clean. The filter setting is also the one you will use the most when vacuuming your pool.

Why does my pool filter pressure go down rather than up?
Note, this particular case is specific to sand (or Zeo-Sand) pool filters. Typically this only happens in a sand pool filter, we explain why below. “After running it for a while the pressure actually drifts down instead of up. The sand filter is trapping dirt because the water is cloudy during backwash and then clears up.

What should you do if your pool filter is low?
If the pressure spikes, immediately shut off the pump. Low pressure in your filter is much less dangerous than high pressure, but it means your filter isn’t doing its job. Low pressure will (almost) always be caused by a problem at or before the pump.
