What is a good PSI for a sand filter?
about 10 psi
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.
When should a sand filter be backwashed?
A good rule of thumb is to backwash once the pressure displayed on your pressure gauge is 8-10 psi over the starting level. Backwashing after heavy rains, treating for algae, or when trying to clear cloudy water will keep your filter working efficiently.
What happens if you put too much sand in a sand filter?
Too much sand and your filter will likely not run correctly or may break when reassembling. Too little sand and you will have cloudy water no matter how much your filter runs. Typically filters hold sand in 50 lb. increments, so you can safely expect filters to range from 100, 150, 200, 250 lbs., etc.

Is 30 psi too high for pool pump?
Generally, if your pool filter water pressure rises more than 10 PSI over the normal range, it’s time to clean – or possibly even replace — your filter. For most filters, 20 or 30 PSI is considered too high, but you should consult your pool professional to make sure that’s true for your model.
How often should you change sand in pool filter?

Why does my sand filter keep putting sand in pool?
Try putting some of the sand you are going to add inside the lateral. Your pump may be too large or the sand level too high in the filter.
