A filter tank can trap or accumulate air. The pump discharge compresses any entrapped air and pressurizes the filter. This creates a risk of explosion or “sudden separation” of filter parts. Filter manufacturers have known about the explosion risk since at least the early 1970's.

Why is the pressure high on my sand filter?
High swimming pool filter pressure is usually the result of a lot of particles being filtered out of the swimming pool water. When pressure rises it is time to backwash the filter if you have that option with a sand or diatomacesous earth (DE) filter.
What ruins a pool filter?
If you don't clean the pool filter often enough, it can wear down your equipment faster. The filter will clog and increase PSI, making it less effective and putting too much pressure on the pump.
What pressure is 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 do I release the pressure from my pool filter?
Shut Down the Pump
Turn off your pool pump and filter. Open the pressure relief valve to lower the pressure in the pool pump. When the valve is opened, water will be emitted but will slow to a trickle and stop after a few seconds. This is normal.
