Pump Motor Noise and Low Pressure

Postby jlrkingwood26 » Wed 04 Jul, 2012 11:03

My Hayward pool pump starts out with 18 psi and then after 30 minutes the pressure goes down to 12 and then later down to 8. The motor is real quiet in the beginnibg and then gets louder and louder. I changed the cartridge filters 4 months ago. Could it be the filter seal or pump cover seals, I'm lost as to the cause.
