Pump problems :(
#5
Is this Grundfos pump an on-demand pump, without a pressure tank? The symptom sounds similar to a jet pump with a pressure tank where the bladder in the tank has a leak. But if this system doesn't have a pressure tank, I don't know what would cause the 10 second intermittent pumping.

Royall, we have a pressure tank system and don't feel the pressure drop in our shower.
