shower pump or bath shower mixer ?

[gwbooks]

Have just had bathroom refit. The bath hot water tap was only trickling hot water. Our plumber who fit it all said it is either the mixer tap or we should have power pump fitted. We went for a shower pump.
Our system is cold water mains and gravity hot water heated by boiler to hot water cylinder. Large coffin cold water tank in loft and bathroom is below this but in opposite corner of house.
Stuart Turner showermate eco S2.0 bar single was purchased and fitted next to hot water cylinder.
The pump cuts in whenever a hot water tap is turned on in the house.

Now, this produces great hot water flow but maybe too much. Pump is very noisy too. Purchased damper pad which fits under pump. This has quietened down the noise a bit.

Question now is should the pump be changed to 1.5 bar or should the bath 2 tap and shower mixer be changed ? Our plumber says the tap unit is not best quality - high price range but is made especially for homebase and says fits all systems.

I'm unclear what your problem is since the pump has been fitted, apart from noise (which would have been mitigated by buying a better pump). Does your mixer still not work?

If your old bath tap was OK, then it was the new tap that was at fault. You have to make sure it's suitable for unbalanced flows/pressures and gravity hot water. I wouldn't have pumped the whole house HW if only one tap was wrong.

Shower part works provided both taps are on full blast. Turn them down a bit and shower valve bit closes.
Really looking for which is more likely to resolve rather than keep buying maybe not necessary parts. Thanks.

Check for pipework restrictions on the bath supply pipework -isolators need to be full bore and flexible tap connectors need to be avoided
