I hope someoone can help me because i haven't been able to find
anything about this online.

Basically i have just baught a new ground floor flat, it was converted
from a house and so my header tank is located in my bathroom. Hence i
have rubbish head / low water pressure.

I believe that if i convert to mains fed i will have to fit a new
toilet cystern to deal with the increase in pressure. I will also have
to fit a non return valve to prevent me syphoning back into the mains.
t heir is a pipe feeding inot the header tank and one feeding out. Is
it as easy as joining the input to the output pipe?

Also I have a combi boiler.What i am unsure of, is whether the boiler
is mains fed and if the increase in pressure will affect the boiler.
The pressure from the boiler seems to be quite good but i think that
this is because it has a built in pump.

I've been told this is quite a simple job.... i'm just looking for a
bit of reasurance!

Thanks

Mark
