Is the mixer newly installed or has it been working satisfactorily for a while?

 

[leslie50]

This is a new sone,but there was one fitted before an old one but it worked.

Is it possible that you have some debris in the filters from fitting it?

 

[leslie50]

have checked that cleaned out filters, could it be that the shower bar itself is faulty.

 

[Paulus]

Assuming that you have checked that the hot and cold water are both getting to the shower and are similar pressure then I suspect the shower is faulty.

 

[leslie50]

Yes I can get just cold and when I turn up the therm it comes through piping hot so I assume both are getting to the shower.

I would go through the commissioning procedure again as a last resort. If you have no joy take it back to supplier under guarantee.

Is it running of the mains or the CWSC? If the CWSC then you need to alter the pipework for it to run off the mains. (A few years ago electric showers would work off stored water but usually not nowdays.)

Did you try and commission it with the shower head attached? If so you might have triggered the prv, which will need replacing.

Try Triton - they don't bite!!

I'm pretty certain it's a thermostatic mixer shower DKIA, judging by the first post.

 

[leslie50]

It is not a electric shower but a thermostatic, and in the instructions it says it is compatible with unvented system.

 

[Paulus]

Sorry leslie, I realise it's thermostatic. I was just trying to be diplomatic in my reply to DKIA.

Have you tried the commissioning procedure? Any joy?

One other thing occurred to me, the incoming hot water temperature isn't too hot is it? Should be absolute max. of 80C.

 

[leslie50]

The incoming hot water was very hot so i turned the thermostat down on the boiler, I have tried commissioning a few times , but still no joy.

 

[Paulus]

If it was over 80c when you initially commissioned it you may have damaged the thermostatic cartridge.

If it was me I'd return it under the guarantee and get a replacement.

Good luck.

 

[dontknowitall]

I thought it was a thermostatic one but googled it and there's also an electric one!

Anyways, hope it gets sorted soon. (Nothing to add, I'm afraid as Paulus seems to be on the button with this one - more diplomacy!)

regarding this problem would a flow reg make any difference.
