Just moved into my new house and the shower is crap! Turned it on and the pump is very loud, it’s also not that powerful. It is more powerful and makes a better noise when you put the shower head lower. For example it doesn’t sound like it’s going to blow up when the shower head is on the shower base, but the higher up it goes the worse it sounds and the less water comes out. Had a shower and after a while the water just reduced to a trickle and stopped whilst the pump sounded like it was running dry and made a hell of a noise. Turned it off and back on and no water would come out. I eventually ran it with the shower head hanging on the base of the shower and it eventually started running again, but it’s still not very powerful at all and makes so much noise. Any ideas?? Also, the colder you set the shower, the slower the water flow, fully cold and it's just a trickle. Fully hot and it's better, but still not acceptable. Any ideas?

Because its a nasty mix of water and electricity , it would be unwise to advise .

I thought that an electric shower would slow the flow(less) of water to get warm water & speed up the flow(more) for cooler/cold water. Sounds like something is very wrong. New,new house or previously lived in?

Mira showers = sh*t. Since I moved into the house in 1992 we have had about 6 put in our 2 bathrooms and seeing as missis tash is the only one that uses our shower, my view is that they are crap. All I can tell you is this. When we changed the original shower I think it was about 8.5 KW off the top of my head. I thought that it was as weak as p*ss so I bought a 10 KW plus shower to replace it. The plumber said that is what people normally do to get a more powerful shower, BUT and this a massive but, The electrical supply may not be able to take the extra power required to run the shower, which could result in a very nasty accident. You really really do need a good plumber/electrician to check it out. Good luck and slip in as you may be starting to smell.

Cold water flow from the taps next to the shower is very strong, so the supply is there. The house is old, probably 1980's I would have said. Shower is newer as it was a seperate WC that has been knocked through into the bathroom and had a shower installed.

Is it a hard water area ? Can you test the flow with the shower head removed, if so, try leaving the shower head in a container of coca cola overnight to disolve the limescale

[danyeates]

It's still rubbish with the shower head removed. I have run it for 20 minutes without the shower head flat out to try and release any possible air lock too

Ok.....

If your Shower has a 'pump' then it's very likely a thermostatic mixer (not electric), which requires both cold AND Hot supplies, and these need to be of a constant and equal pressure (not mains fed, but supplied from a tank).

The Cold supply (if done correctly) will be fed from your main storage tank (in the Loft?)... from your description it would seem the problem is with this cold supply, ie it's either blocked/restricted or Air-locked.

There 'Should' (somewhere) be isolation valves for the hot+Cold supplies to the Shower, if you can find these and turn them off, you could then remove the shower valve and check the internal filters on the inlets (if fitted) you could also then run the cold (into a bucket/your bath) which will prove if the restriction is on the Shower valve or it's supply pipe...

Reduction in pressure on raising the shower head is 'usually' an indication of Low head Pressure, however if fitted correctly the pump should overcome this....... thats what they are for.

If the pump is of the 'Twin impeller' type (one side does hot, the other cold) then it's possible the cold side impeller could have failed......... is the Hot pressure Ok?..

The shower worked perfectly fine the other day, REALLY powerful. But turned it off, then back on later on and the exact same problem. Hot water pressure around the house is fine. From the shower it's just enough to shower with, but pretty useless.

By the way, the shower is a Mira Event, made end of 1998.
