Good morning Tellie,
Newhaul suggested that I talk to you. Do you know anything about the spool valve on a Powersurvivor 35? When the cleaning head is on water seems to circulates ok. When the regular head is on it builds up enough pressure to stop the pump. water comes in a steady stream from the tank discharge until the pressure dissipates. NO water exits as brine discharge. Doesn't this point to the spool valve? Katadyne won't even let me talk to a tech since it is discontinued.
