Bath Shower mixer tap

[stevecsmith77]

Hi. I'm wondering if someone can help.

I have fitted a mixer tap with shower attachment on my bath. When I use the tap the water mixes fine whilst coming out of the spout. However when I use the shower attachment I either get scalding hot water or stone cold water. The tap doesn't seem to mixing using the shower attachment but is fine when coming out of the spout.

I get decent flow out of the shower head for hot and cold but as I say it just wont mix. My hot water is fed from a gas combi boiler and the cold is mains fed.

Can anyone shed any light on what the issue may be? If the taps are at fault i'll remove them and get them replaced but don't want to do it if its not the taps at fault.

It is driving me mad!!!

Is the mixer thermostatic? It should be. Check you've fed hot and cold correct way round and check holes in the shower head aren't too tiny.

Its just a standard mixer tap with a shower attachment. You pull the knob up in the middle of the tap and water diverts out through the shower head. As I said Hot water comes out fine and cold water comes out fine, however they just wont mix.

You'll struggle to get a satisfactory shower from a combi with a non-thermostatically controlled mixer.

taps are not faulty, they should be thermostatic, you could fit a TMV under the bath to feed the bath taps instead of replacing them.

Well I should at least be able to fiddle with the hot and cold to get a mix. What I'm asking is do you think there is a problem with the taps or is it an issue with the way my water system is?

You've fitted the wrong mixer for your set up.

 

[stevecsmith77]

Ok then. What sort of mixer do I require?

 

[Tibbot]

Again, a thermostatically controlled one.

Such as part no. 17853 at BES.

This one's wall mounted but you could probably connect it to 'stubs' of the mixer tap you've already fitted.

Or part no. 16933, but that's rather more expensive...

Thanks to all who replied. I've now managed to get the Hot and Cold to mix by fitting a wider bore shower hose. The one that came with it was 8mm so I purchased a 11mm hose and I can now get a decent temperature for a shower.

Just make sure no-one runs any tap while you're in the shower.
