Frequently Asked Questions: Trevi 1/2 Inch Cold Flow Cartridge – A952501NU

Question: My shower’s water flow is slow. Do you think there’s a blockage in the cartridge?
Answer: If the water supply is okay, yes, the cartridge may be clogged resulting in the weak flow of water. Getting a new Trevi A952501NU may likely normalize water flow.

Remember to grease the O-ring of the new cartridge before installing it.

Question: The plumber said the cold cartridge has to be replaced to stop the leaking. Can you confirm it?
Answer: Your plumber must have already checked what needs to be checked regarding the shower valve. Leaks that originate from the cold side may be the result of a worn-out cold cartridge, hence replacing the old one with a new A952501NU can stop the leak.

Question: We will be switching to a mains fed system. Will the Trevi A952501NU work?
Answer: Yes, the A952501NU is compatible with a mains fed system.

Question: How do I remove the spent cartridge from the shower unit?
Answer: You can grip an adjustable spanner on the hexagonal nut of the old cartridge and turn it anti-clockwise to remove.
