What causes high PSI in pool filter?

High pressure usually indicates a dirty pool filter, time to backwash or pull out the filter cartridge for cleaning. Be careful with high filter pressure, as filter tanks can rupture with deadly force.

What psi is too high for pool?

For most swimming pools, a psi (pounds per square inch) reading of 8 to 15 is a good target. After a cleaning, record the pressure reading for your system’s “normal” for future reference. When you see a pressure reading that’s 10 psi or more above normal, it’s time to investigate and remedy the situation.

How do I know if my pool pressure gauge is bad?

With the pool pump off, check your gauge—it should read zero. If it doesn’t, or if it reads zero when the pump is on, your gauge is probably ready to go. Examine the gauge dial for warping, which could indicate that you’ve got a broken gauge. You can also give it a flick, and see if the pressure momentarily pops up.

What should the pressure gauge read on pool pump?

The pool filter pressure should be steady, operating in a range of +/- 10 psi. When it’s outside this range, very low or very high, then you know that something’s wrong. Some gauges allow you to set the clean and dirty range, or you can write it on the filter tank with a marker.

How do I lower the PSI in my pool?

You can reduce the pressure in your swimming pool pump by cleaning out its filters.

  1. Shut Down the Pump. Turn off your pool pump and filter.
  2. Remove the Cover.
  3. Take Out the Pump Basket.
  4. Rinse the Pump Basket.
  5. Remove Any Debris From the Impeller Port.
  6. Replace the Cover.
  7. Examine the Air Relief Valve.
  8. Monitor the Water Pressure.

How do I reduce the pressure on my pool pump?

Relieve the pressure by turning the air relief valve on top of the filter counterclockwise. Water will spray out of the valve while the pressure gauge decreases to 0 psi. Take note on how your basket is positioned within the pump. Use a garden hose to rinse out the debris.

How do I lower the PSI on my pool pump?

Can a pool filter explode?

Pool filters do explode and can cause damage to property and serious injury or even death. Since 1982, the Consumer Product Safety Commission has recorded at least 23 incidents of pool filter explosions.
