Morning.
Ive just moved into a house thats 3 years old. My Old house of 2 years old had mains water pressure, with no tank in the loft. This meant it had a wicked shower.
The new house has a header tank in the loft, and the shower is horrid!
I'm looking at getting a pump installed in the loft to increase the pressure.
Has anyone had this done, and roughly how much should it cost?
A 1.5 Bar Salamander pump in B and Q is about £100.

Technically the plumbing work can be done by anyone, but the person doing the plumbing should be competent. You only currently require a CORGI registered plumber for work on gas. Most power shower pumps come with flexible linkages that you just cut a section out of the relevant pipes and then push-fit the linkages onto the pipes and the pump.
The electrical work is required to be done by someone who is competent.
The work is also required under BS7671 (Wiring Regulations) and Part P (2006) of the Building Regulations to be certified if there are any material changes to the circuit (e.g. the installation of a fused spur to supply the pump).
If the pump was connected directly to an existing, unused, fused spur on a circuit with adequate capacity then there is no requirement for certification since it is the connection of fixed equipment to an existing connection unit.

all depends on your shower
its not just a case of cut pipes and stick a pump in
you need the shower to be a mixer valve type
if so you need to see where the hot and cold pipes connect to your current system, both of these need to go through the pump
and you cannot connect mains cold to the pump it must come from the same header tank that supplies your hot water cylinder......
the simplest way is to fit a single impeller pump on the hot supply to the shower and fit check valves (anti-return) in line to prevent cold water feeding into the hot system...not all that good though

Its got a mixer on it, and the pipe work goes up into the loft, one into the header tank and one into the hot water tank.
Ive got a block coming round tonight to look at doing the job, as quite simply i cant be bothered!
-
so long as the cold feed comes from the tank , which as you describe then it should,
then it is quite simply a case of fitting a twin impeller pump inline .

a friend of mine from work had the same issue so he fitted a pump - it switched on automatically when it detected flow. unfortunately a burst pipe south of the pump meant that it had a field day pumping water through his ceilings for 7 hours till he got home.
:shock:
