Bad pressure going to showers upstairs

[roamer808]

Sister got a load of work done. Plumber was a muppet. Cylinder was left downstairs and 2 new Mira thermostatic pumped showers put upstairs. Of course the pressure from the cylinder is barely enought to get the water upstairs and to the other side of the extension.
Would anyone advise on adding a small booster put on the hot supply to help it get every where in the house.
The pressure in the two new bathrooms is poor and the showers are making a lot of extra work noise.

Moving the cylinder is major work, which of course should have been done in the first place.
I was thinking of some small single flow pump around the 1.5bar area. Just enough to help the water.

you can't add another pump to the miras that already have a pump.
if they are struggling to perform sounds like your lacking flow.
these showers only require gravity feed to them the pump does the rest.

what model are the showers ?
and where is the header tank that supplies the cylinder ?

The position of the hot cylinder has little, if anything, to do with poor pressure and flow rates.

The pressure available is determined by the position of the cold water storage tank feeding the hot cylinder.

The maximum flow rate at that pressure is determined by the length and sizing of the cold feed and the hot water outlet pipework to and from the hot cylinder.

Partly closed or faulty gate valves in the cold feed to the hot cylinder are far from unknown.

they might use diferent laws of physics in Ireland.

That helps a bit. Tank is in the attic where it always was. The feed to the cylinder is 3/4" and the feed out is 3/4" in the immediate run. What it does after that is guesswork. I think it is down to 1/2" quickly after leaving the hot press. The head pressure is fine, given the height but the pipes could be the problem. O well.. crap pressure for the sister.

Will this lead to a short life for the showers?

If your starving it of water yes and a invalid warranty on the shower.
