Frequently Asked Questions: Brass Thermostatic Cartridge

After years of use a brass thermostatic cartridge can begin to wear out. The inability to regulate temperature, inadequate flow rate and drips are among the signs the shower cartridge requires replacement.

Question: Which way does the brass cartridge unscrew from the shower valve?
Answer: To extract the brass screw thermostatic cartridge you will need to turn the cartridge anticlockwise. It's preferable to use a box spanner as this will hold onto the cartridge more firmly, especially if the cartridge has seized up with limescale within the valve. If you are still finding it difficult to turn, try tapping the spanner with a hammer. The sudden jolts can help loosen the cartridge.

Question: Will soaking the brass thermostatic cartridge in a de-scaler fix the temperature problems in the shower?
Answer: Soaking the brass thermostatic cartridge in a descaler may help in some situations to get the cartridge working, but this is often a temporary solution which doesn't usually last for more than a couple of months. Once the cartridge has got to the point where it has stopped working, damage to the inside of the cartridge has already begun therefore the only real long term solution is to replace the cartridge.

Question: When I turn the shower on it takes a long time to get hot and then the temperature keeps spiking up and down. Is the problem with the brass cartridge or is it something else?
Answer: First you will need to check whether there is a steady constant flow of hot and cold water reaching the shower from the boiler. If there is, then you should check whether any gunk or debris is blocking the cartridge gauzing as this can block water flow, affecting showering performance.

Should the above point be in order then we would think the problem is a faulty cartridge. Replacing the brass thermostatic cartridge should get your shower back up and running again.
