FAQ: Crosswater Thermostatic Cartridge CP0000250 / GP0000250

Here are some of the most common questions regarding shower repair using the Crosswater CP0000250.

Q: Crosswater shower is only producing warm water. Is the CP0000250 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 Crosswater thermostatic cartridge CP0000250.

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 are 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 Crosswater CP0000250 thermostatic shower cartridge issue.

• The shower valve will need 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 Crosswater CP0000250 or GP0000250 thermostatic cartridge. 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 scalding hot. What is the problem?

A: In this scenario, it sounds like the Crosswater thermostatic cartridge CP0000250 or GP0000250 is faulty.

Q: How do I remove the thermostatic cartridge?

A: Remove the shower handle which is connected to the Crosswater CP0000250 thermostatic cartridge. Then remove the fixing plate. Use a 22mm box screw to unscrew the shower cartridge anti-clockwise.
