Question: What is the flow valve cartridge? I will also need that part for a more comprehensive shower repair.

Answer: The flow valve cartridge for the Bristan Buzz is part number SL20T180A.

Question: There is no spring on the cartridge when I pulled it out of the valve.

Answer: The spring is left inside the valve. Look inside the valve and use pliers to remove the spring.

Question: Our Bristan shower is running only hot water even at the coldest setting. Will replacing the Bristan TWK-25 cartridge fix it?

Answer: Before concluding if a cartridge change is needed when the shower valve is delivering only hot water, there are two things that need to be checked:

1. Both hot and cold water supply pipes must have constant and consistent water pressure and water flow. The pressure of the two pipes must be equal. At the same time, each of the pipes must be clear of any blockage; in your case the cold water supply.

2. If the pressure and water feeds are good, then the thermostatic cartridge might be what caused the problem. Replacing the Bristan TWK-25 might alleviate the issue and get your shower to run like before.
