Hi Armand.

Sounds like some crud broke loose from mineral build up in your heater, (do you fllush your heater on a regular maintenance basis?) or off your pipe walls and are now blocking the inlet ports of the cartridge. The solution would be to shut the water off, open up the valve,(see image) and check and clear the inlet ports on the cartridge. Before you reassemble the valve turn the water back on for a moment to flush out the supplies. If you need instruction on how to flush your heater of open up the valve click on back. Good luck, Tom
