Noisy new shower

[SuperMario80]

Hi,

I fitted a new mira duo for a friend. It is now making a whistling noise, and he is complaining that the hot water is a bit sporadic. The old shower was a new team. This had some sort of blending/blalncing valve fitted under the bath. The reason he wanted the old one replaced was that it stopped letting hot through. I removed this valve as I believed it was faulty.

The system is a combi boiler in a small ish 3 bed house. The bath/shower is pretty much directly above the boiler. Do you think the cold water needs slowing down?

Why didn't you replace the part that you thought was faulty?

My friend wanted a new shower, so had bought one anyway for me to fit. Not sure what the old shower model was exactly.

Can I purchase a universal balancing valve? Or will I need a specific Mira one?

Thanks in advance.

first ignore the cut and paste merchant (school holidays)

pressure balancing valve you can get any make

if thats what you removed

looks a bit like a flying saucer

Yes, but was it a balancing valve, or was it a thermostatic mixing valve?

This is why I asked about the old shower valve. Do you know whether or not it was thermostatic?

 

[SuperMario80]

Ah, I see. Not too sure about old valve.... But I'm pretty sure it was a balancing valve I removed. i have it somewhere so can check and get back to you.

No idea if the original poster is still after an answer, but....

we had a Mira mini duo installed that started making a noise. Turns out the installer hadn't flushed the pipes properly that resulted in blocked filters meaning the thermostatic mixer couldn't get the right flow of water through.

Try cleaning the filters would be my suggestion.

I checked the filters already, all seemed ok there. Guys, it was a pressure equalising valve I removed. ANyone know where I can get a replacement, had a look online, but they all seem to be integral with the shower valve!

Quick update:

Fitted new pressure equalising valve. This cured the noise, but still not letting through enough hot water. So cleared any possible airlocks, still no hot water coming through with shower head off, only warm. Customer mentioned that when he fills bath he has hot tap on half way as the boiler can't cope with it open all the way and runs cooler again. I've fitted the flow regulator that came with the shower, this slightly improved it.

Tried throttling the ISV right back, this again got it a bit warmer, but there was now not enough pressure there.

So is it looking like the heat exchanger could be scaled up in the boiler?

goodnight Cowboy, so many basic errors its not real

tell your friend/customer you have not got a clue, give him/her back all the money you have ripped them off for, and chalk it down to experience
