I have a pressure assist toilet in the third floor bathroom. It seems to be causing the pipes to rattle. Water Hammer. All night long, the pipes will rattle every 30 seconds or so. If I turn off the water valve into the toliet tank the rattle will stop. With the valve on the pipes rattle every 30 seconds or so. Sometimes it will stop for a few hours then begin again. I don't notice any water movement in the bowl. Could the pressure assiste have a bad valve or something. Can it be adjusted? It is a Kohler Model K-3505. Any help would be much appreciated. :wall:
