Question about Shower Hardware

1 Answer

Shower either runs cold or extremely hot

Mixer shower has been working fine for 2 years, has suddenly developed a problem with the thermostatic control - Now will only run cold or very, very hot!
I believe there's the thermostatic control is installed in the pipework and can be accessed quite easily, am wondering if it could be that it is scaled up. Just don't want to invalidate warranty by opening to access the control if it's unlikely to be easily fixed by de-scaling.
Shower should be under 5 year warranty, but was fitted by a contractor who must have the actual receipt for it and I have been unable to contact - Triton have said they must have the receipt before they will replace/repair it.
Would be very grateful if anyone's had similar experience, or knows what the fault is likely to be, and could let me know.

    Thanks Richie - Am in the UK & have finally got a response from Triton - they are hopefully coming to take a look - still bitching about us not actually having a receipt, but say they should be able to determine the age of the shower and will accept that as still being under warranty!

Hi ya, if its a triton shower valve & only 2 years old it should have a 5 year guarantee, ring Triton & arrange a service call.
it sounds as though the filters could be blocked & more than likely the thermostat requires replacing as its more than likely scaled up?

You never mentioned where your based UK or abroad?

There is no hot water

Hi Marshall,

Do you mean that no hot water is reaching the shower, or do you mean that no hot water is coming out of the shower. The answer to this will determine where the problem is.

If no hot water is reaching your shower, then there is probably a problem with the boiler or the pipe is blocked. You can easily test this. You can turn on other faucets in the bathroom to check whether any hot water is reaching those.

If the problem isn't with the boiler and the shower is in fact receiving hot water, then the problem will be with the shower mixer valve, specifically the thermostatic cartridge. The cartridge controls water temperature. The inner workings of the cartridge move up and down to adjust the amount of hot and cold water entering the cartridge. If it has seized up, the moving part can get stuck in a certain position. It sounds like this could be the case with you and therefore replacing the cartridge should in theory fix the problem.

Hope this helps. Shower Thermostatic Cartridge Spares

Not getting any hot water all is turned on but only cold comes out i have hot water out of all other faucets but this one

There are a number of things that could be wrong. Most likely a breaker is tripped (or fuse blown), an element is burnt out, or there is a faulty water heater thermostat. From my experience, I would suspect a burnt out element but I would check the breaker first since it is easiest to check.

Shower runs much cooler in winter this is the third go one we have had in the last 10 years all reacting the same way

Hi, going off a previous problem with my shower being colder in winter i found a simple solution. The copper water supply pipes in my house were not insulated and in the colder air that made a dramatic difference in temperature with the hot water being cooler and also because of the much cooler water from the cold supply going into the shower mixer. Please have a look to see if your pipes are all well insulated.

Mira mixer cannot balance temp.either scalding hot or freezing cold

I suspect you have gravity fed hot water system and the mixer cannot balance the high pressure of the cold mains against the low pressure of the hot water.
Either install a shower pump. Means installing electrical connections and quite a bit of plumbing
Or a mechanical pressure reduction valve on the cold input pipe to the shower

Shower goes hot and cold

If you are having trouble only at the one fixture (shower), and no where else, the problem is most likely in the shower valve...which either needs new cartridges, or a complete replacement.
hope this helps

Installing a Mixer Shower from a Combi Boiler.

hi there, your boiler will perfectly match the mira excel ( a great choice i might add) a 24cdi will give about 9.8 litres a minute flow rate hot water.
The mira excel is suitable for any plumbing set up and there installation instruction are very well laid out & their helpline is fantastic.
The hot water will fluctuate accordingly to the time of year as the cold water temp coming into the property will vary. but the boiler will modulate to compensate.So in brief in the summer you will notice it hotter than you would in the winter, this has nothing to do with the boiler just the incoming temp of the cold water.

Cold water suply filling up header tank in loft thru hot water suply on shower.

hi did you run a seperate cold water supply from the storage tank to the shower pump & also a seperate hot supply from the hot water cylinder, it sounds as though the cold water is crossing into the hot service & pushing its way up to the tank as its the only way it can go, sounds as though the cold water connection to the shower is not tank fed & possibly directly off the water main.?
