how to solve noisy shower pump?

Question

2.0 bar shower pump, got 4 connection pipes, person who fitted only connected 2 of these to hot water supply apparently to boost hot water pressure. would this cause noise because of to much pressure, do other 2 pipes need to be connected to cold water

i have had an electric shower fitted and it's thermostatic controlled, i think it was fitted to the cold water supply pipe in the bathroom not in the tank.

i can actually feel the pipies vibrating under the floor boards so do you think that the pressure is too much for the pipes and if so how can i solve this probem.

if the pump is set too high, how do i slow it down

thank you gentlemen for your assistance, as you may have gathered i'm a woman, but if i can solve a problem myself with advice, i will give anything a bash.

Answer 1

The other 2 pipes are for the cold supply, so it could be that the noise is being caused by running that side of the pump dry

Answer 2

first all electric showers must be connected to a rising main ..never to a tank ..other wise when you have a shower you could get old stagnant water into your mouth ..as for the pump ..it might be set too high as some pumps can be slowed down ..it may all so be positioned wrong ..i fitted a shower pump recently and the makers insisted it was mountedwith a carpet tile on the bottom and then a 50 mm paving slab and then the pump even though the pump was sitting on airing cupboard floor ..and the pipes should not touch any joist or flooring

Answer 3

Not strictly vital to have the other pipes connected,depending on the available pressure in the cold supply.Pipes should be connected to the pump using flexible anti vibe hoses.Pump should also be seated on a anti vibe pad,and not screwed down!These pumps can not normally beturned down,they are a fixed speed.

Answer 4

concerned a twin impeller showerpump is only connected on one side, they should have fitted a sinlge impeller pump ie 2 connections. what is happening when the pump kicks in bofh sides will run and as these pumps rely on the water to aid the lubrication process the unconnected side is running dry causing it to wear out prematurely, and probably causing the racket. If it was fitted recently suggest you seek redress with the installer. As it has not been installed correctly you will not have any warranty, and you will have to concider replacing it again

good luck.

Answer 5

How do you get cold water to the shower ? email me !
The first answer is probably the right one !
If your cold water is coming straight from the mains ? you have got the wrong pump fitted !
