Can soemone advise please.....I have terrible HW pressure in my kitchen - probably the result of too many bends installed by incompentant plumbers in the years before I moved in.....I bought a (brand new) Grundfos 15-90 pump (http://www.grundfos.co.uk/web/homeUK...ag/DMAR-6RZKWV) for £15 which I thought I;d try before the inevitable task of having to lay a new run to feed the kitchen with its Hot water from the Cylinder upstairs.

The easist point of installation is in the airing cupboard upstairs - by running it on the outlet down pipe that comes from the top of the cylinder I was hoping this might at least help...however the spec for the pump says that it requires .2 bar (2m head) minimum on the inlet side of the pump - and by installing it on the pipe about 20cm below the level of the output pipe on the cylinder I can see how this is possible.

There are no real alternatives for the location of the pump without the same dreaded removal of carpets and chipboard flooring which I'd quite like to avoid - and of course, if I'm doing that, I may as well lay the new pipe run anyway......what should I do???

I had the same problem after installing a high pressure only 'mixer' tap
in the kitchen - I couldn't find a low pressure one I liked. I installed
the pump under the sink. Works a treat. The other hot water outlets in the
house are fine, though.
