Bearing
The drive bearing transfers the motor movement to the diaphragm. It wears over time, which you hear as louder running.
Diaphragm
The 4-chamber diaphragm pumps the water in the head. A cracked or worn diaphragm lowers pressure and flow or causes a leak.
Before repair
Disconnect the pump power and open a tap to relieve system pressure. After replacement, tighten the head screws evenly and check for leaks.
