This cartridge fits into the mixer valve by screwing it in. When removing this cartridge, you might find it difficult finding a spanner which will fit. First, unscrew the chrome casting. Next use a 22mm box key to unscrew the cartridge. A box screw will give a neat fit, which is important as it's important to take not take the edges of the spline of the cartridge.
The cartridge is usually used in shower mixer models where there is a red override button.
The CP0000250 is the new replacement for the older GP0000250 thermostatic cartridge. The new CP0000250 may look a little different to the old GP0000250 but these are actually interchangable. Therefore if you have a GP0000250, you can use the CP0000250 as a replacement.

Frequently Asked Question
Q: Shower is only producing warm water. Is the thermostatic cartridge the problem?
A: Please ensure that the shower is receiving hot water. If it is and the water coming out of the shower is still only tepid, then the problem will be the thermostatic cartridge.
Q: I have just installed a brand new combination boiler (which replaced a gravity fed conventional boiler). Now I am having trouble controlling the water temperature, where even if I turn the temperature dial to its coldest setting, still only hot water comes out of the shower. What is the problem?
A: If there is both hot and cold feeds to the shower mixing valve, which are feeding both cold and hot respectively, the problem will either be a pressure issue or a thermostatic cartridge issue. The shower valve will need a relatively equal pressure between the hot and the cold so first check the water pressure. You can adjust this on the combi boiler or install a pressure equalizing valve. If the pressure is equal then the problem will likely be the thermostatic cartridge and replacing it should fix the problem.
Q: I have a pressure reducing valve, a condensing boiler with 3.5 bar pressure from the cold and 1.5 bar on the hot. The water is only coming out scolding hot. What is the problem?
A: In this scenario, it sounds like the thermostatic cartridge is faulty.
Q: How do I remove the thermostatic cartridge?
A: Firstly remove the shower handle which is connected to the thermostatic cartridge. Then remove the fixing plate, then use a 22mm box screw to unscrew the cartridge, anti-clockwise.
Simple Safety Guidelines in Replacing a Shower Replacement Cartridge
Standard thermostatic cartridges made for showers have a lifespan ranging from a year to twenty years and above. Apart from normal wear and tear, its functional lifespan can decrease due to the level of water hardness, uneven water pressure from a homeâ€™s plumbing system, dilapidated o-rings, or a faulty wax thermostat element.
Before making an effort to change a valveâ€™s thermostatic cartridge, there are a few things to remember to prevent uncalled-for purchases and unnecessary injuries.
Take the old cartridge out of the valve unit and measure or take a photo of it. This will ascertain that you will buy the right cartridge that goes with your shower valve. If unsure of the cartridge type, show the photo to your spare part supplier and ask.
It is important to shut off hot and cold water supplies. Not isolating water supplies can result in burns and shock if by any chance water is delivered through the outlets. Turn the supply off direct from the water meter of isolation valves cannot be located.
To prevent small parts from unintentionally entering the drain, block the drain with a stopper.
Always calibrate the cartridge to your preferred temperature, usually to a lukewarm 38â„ƒ or 100.4â„‰.
