    cut into your hot&cold taps at your bath with t joins and take the feed for them for your mixer shower!just blank off the old shower pipe.its very easy to do especially with flexi pipes and push fittings.you cant go far wrong.

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

Your shower valve has an temp equalizer valve in it, you will have to take it apart, clean all the calcium or debris from it. flush out the hot and cold lines with valve dismantled , cover drain to make sure you don't lose any parts. reassemble with Vaseline. good luck.

Mira Excel Mixer shower, it doesn't seem to have an output of water even when connected to a fairly high pressure supply, why is this?


Most shower heads have a flow restrictor in them to meet calf. standards. These can usually be removed but check your local and state laws first. Thanks

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

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.

We have two 16 year old shower faucets (house was built in 1993 by Del Webb). Can't tell what model they are. We are guessing they are Moen Legend 3175 (one handle). Problem seems to be pressure balancing...


This is a common problem with this type of shower mixer valve. They are not very good at regulating with pressure change. Your options are somewhat limited to not flushing the toilet or using any other taps when in use, repalce the mixer valve for a modern ceramic unit or installing a 2 vane hot & cold shower pump.

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.
