Shower Pump

ifti

hi

a family member has cold and hot water tank system supply and want to get a shower pump installed so that the pressure is better when using the shower and bathroom.

can someone tell me how hard it is to install, is it a DIY job.

i thought all you do is cut the right pipes that are going to the bathroom and fit these using the push fit pipes, seems simple.

also is the Salamander RSP50 the best one to go for ?, there's a Grundfos watermill one which is the same price, but has better features like Automatic thermal overload protection.

not sure which is quieter of the two.

thanks in advance

yes its easy but the difficult bit is power -need to take a supply from your board which i believe has now to be done by a qualified electrician

You can't just cut the pipes "going to the bathroom". If you're far enough from the bathroom, they'll be 22mm and the pump will run whenever you brush your teeth or flush the loo.

Fit it too close to the shower head and run the risk of cavitation and burning out the pump.

Ideally it needs to go near to the hot water cylinder with it's own hot feed tapped separately into cylinder. Would have used an Essex flange in the past but these are not approved anymore.

It's not really a straightforward DIY job unless you've done a fair bit of plumbing. Electrics are easy if there is already a spur in the cupboard for the central heating controls.

Hi Mutton Geoff, when we had ours done 10 years ago they used and Essex flange I believe, it comes straight of the outlet on the hot water cylinder. So why aren't these approved anymore?

Also, my pump doesn't always switch off anymore when you close the bath taps, I have to fiddle with the taps for it to switch off, anyone know why that is happening and can it be fixed?

Cheers.

There are magnetic float switches that detect the water flow at the pump outlets. These get sticky (usually calcified) after time and are a relatively easy job to change. Contact your pump maker to order spares. Although only one of them may be sticking, it's worth changing both while the pump is disconnected.
