Common Questions:
Q: My Mira 415 shower is dripping when the water is turned off. I was wondering if a new cartridge would fix the dripping problem?
A: In the majority of cases, if your shower is leaking then replacing the cartridge with a new one should fix the issue. The cartridge you need controls both temperature and flow, therefore if there is a drip from the shower head then the cartridge is at fault.

Q: I only get cold water when I turn the temperature down to its coldest setting. When I take the setting off its coldest it turns scolding hot going from one extreme to the next. Do you think this is a cartridge problem? I have a combi boiler.
A: As a test you could try reducing the combination boiler flow to its minimum and then ensure the shower valve is receiving a constant flow of hot and cold water. If you are still experiencing a problem at this point then it sounds like the cartridge is faulty and you'll need a new cartridge for your Mira 415 shower.

Q: Does the red temperature stop ring, white nylon collar and black o'ring come with the cartridge assembly?
A: These parts for not come with the cartridge. You will have to use those parts from your existing installation. These parts rarely break so you shouldn't have a problem.

Q: When I turn the shower on it makes a vibrating noise. What's the issue here?
A: The cartridge may be old and worn out, or the pressure may be too high. This will cause the 415 cartridge to struggle mixing the hot and cold water properly. The sound you hear is probably the pipes and the valve vibrating because of this problem. Replacing the cartridge is the likely solution.

Q: I get hot and cold water fluctuations. I know the shower is getting hot and cold water so do you think it is definitely the thermostatic cartridge which is at fault?
A: If there isn't a big imbalance in water pressure between the hot and the cold and the valve is receiving hot water, and there are no blockages in the valve then the problem is likely the thermostatic cartridge.

Q: My shower is from 1986. Is this the cartridge which I need?
A: Mira 415 showers which were made between 1985 and 1991 use the grey version of the cartridge - Mira 902.91. Generally these would have a yellow temperature stop ring (and the cartridge is visibly grey).
