Frequently Asked Questions: Hudson Reed SA30049 (ULTRA-SA30049) Thermostatic Cartridge

Question: I have thermostatic shower valve problems, what is the solution to this?
Answer: The three main problems which are symptoms of a faulty thermostatic cartridge are:
1: Water temperature isn't steady or constant (i.e. fluctuating), or the temperature of the water just isn't correct (i.e. you have it set at 38 Celsius but the water is cold or scolding).
2: The thermostatic temperature handle is harder to turn than it used to be, or it might have even be very difficult to turn.
3: The water flow is either low or not steady.

These are the classic symptoms of a thermostatic cartridge that has a problem.
Solution: The best thing to do is replace the cartridge; in a lot of situations it'll solve the above problems.
