back boiler and shower mixer tap

[lenney]

Hi guys

I have just installed a shower mixer tap over my bath but it does not seem as if my old back boiler has enough pressure to pump hot water out of the shower

What can i do?

Cheers

By the sounds of it you have connected the cold supply to the mains and it is overpowering the hot. How much head of water do you have?

I have just connected them to the taps which was already in the hot tap works great just not enough power to push water up to the shower head

the tap below the shower works and the pressure from it you would think would be enough for the shower but there is nothing at all coming out for hot

The pressure of the shower is determined by the height difference between your shower head and the cold water tank in the loft, its got nothing to do with the back boiler.
