Pool Filter Pressure Problems

Pool filter pressure gauges are typically a 0-60 psi gauge, with a 1/4" NPT threaded attachment. The threads can be on the bottom of the gauge (used on top of DE, cartridge and side mount sand filters), or the threads can be on the back of the gauge (backmount) for use on sand filters with the valve on top. A 0-30 psi gauge can also be used for ...

ENE 806: Backwashing of Sand Filter Medium drop) across the fixed bed will be a linear function of flow rate at low superficial velocities when flow is laminar. As the back wash velocity is increased, a point is reached at which the pressure drop is sufficient to bear the weight of the solid particles.

Sand filter - Wikipedia

The final key design point is to be sure that the fluid is properly distributed across the bed and that there are no preferred fluid paths where the sand may be washed away and the filter be compromised. Rapid pressure sand bed filters are typically operated with a feed pressure of 2 to 5 bar(a) (28 to 70 psi(a)).

Selection of optimum filtration rates for sand filters

The early rapid sand filter systems were proprietary devices, the first one patented by I. W. Hyatt in 1884. A number of others were on the market in the mid 1890's when 0. W.
