Introduction
It may be that the pump no longer works properly and builds up the pressure sufficiently. Often a valve ball inside the pump is defective, you may be able to replace it. But it may also be that the solenoid coil is no longer working. Pump Ulka EP5GW is not very expensive and replacement is quite simple.
