I have an Aquariss shower mixer that runs cold when fully on

There should be a hot water limiter behind the knob on the shower - shingle handle, undo the handle and move the adjustment to allow more hot water. Not familiar with mira discovery mixer

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.

When installing a flexishower head, install it in front of the actual shower head with a diverter switch. If you try to operate two shower heads at once, you may suffer poor water pressure. There are handheld shower sets sold which are installed to existing shower assemblies with ease. Rememer to use plumber's tape and protect your stainless steel by wrapping you pliers teeth in electrical tape.

from a plumber all hot and cold connections on all major showers are hot on the left and cold on the right just like the taps on your sink or washbowl

This sound like you need to reduce the inlet pressure of the cold feed to the mixer. If there is no 'non return valve' fitted and the cold feed pressure is too great, i can in effect push back the hot water feed and reduce the temp. So how to fix?? trace back the direct water feed to the shower faucet/outlet feed and simply reduce its pressure by 1/4 turning the 'in-line' stop valve the plumber should of fitted if he was any good at his working standards.

Hope this Helps

Most likely bad solder joint or leak where shower arm is screwed into fitting.

Sounds like you need to replace your shower valve, especially if this is the only fixture in the house being affected. You could try to replace the cold water cartridge first. Hope this helps

you mixing valve may be going bad,do you have hard water? you may just need too take it apart and clean it

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?

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.
