We're currently experiencing rather low pressure in our upstairs shower. It is fed by a header tank which goes into a new topliss brand mixer. The header tank in question feeds the whole top story with hot water and no where else seems to experience the low pressure we get with the shower.

To explain out setup better, the house is two story with showers both upstairs and downstairs. The downstairs shower is also fed by another header tank which is right beside the other one and has no pressure problems.

Would raising the header tank for the upstairs shower improve the pressure much? It looks like we can raise it about 250mm. It is currently 1.6m above the shower head, which is 200mm above the recommended height.

Any other ideas on how we can improve the water pressure in the shower would be appreciated as well.

Thanks,
Andrew.

i think you need professional care here. contact a plumber and let him do his work. you can go for DIY but it can cause you lots of mess which might take lots of money to redo. 

hi sooms, convert to gas hot water then all your problems will be over,cheers
