    DE Filter - High Pressure in Filter and low flow and CLEAN filter grids

    High PSI Pressure in filter

    I have a Pentair Whisperflo 6 W/DE filter, top manifold. The Breather tube has a hole in the mesh cap. The manifold has a hairline crack. Could this be the cause of the high pressure? The pressure never goes pass 33psi. I cleaned the filter, found and replaced a cracked pump impeller...
