low pressure from hot water cylinder

[atakd]

Hi
I have just fitted a bath shower mixer taps I have plenty of cold water pressure but the hot water comes from a cylinder which is on the same level this has no pressure to function the shower. Is there any pumps that I can buy that will increase the overall hot water pressure from a gravity fed tank.
thanks kate

how much pressure was there before the new mixer? has the mixer been put on its own feed from the tank and not just conected to the standard pipe work?

Thanks for the question
I am not sure how much pressure there was before. I think the cold comes in from mains and hot comes from cylinder.

You need to make sure that the hot supply to the shower has come off a 'surrey' flange or an 'essex' flange if it is going to a thermostatic valve. You also need to ensure that the valve supports low pressure water flow.

The pipework from the hot tank will need to be installed correctly as you may find you will have an air gap from the cylinder to the valve, causing the water to 'trickle' through the hot pipe.

You can get single impeller pumps that will pump the water, but normally that only applies to areas where overall water pressure (cold) is low.

Check the compatability of the shower valve before diagnosing any faults with the installation.

thanks for the advice I think I will have to get plumber in

be sure to always fit a thermostatic valve, as incorrect instalation of the cwsc can result in scalding!!!
