Help! Low pressure to electric shower install

[MOSSEP]

Electric shower problem.


Had an issue with 2 electric shower installations today in an office block due to low water pressure. Due to me not checking out everything thoroughly when I quoted for it, I missed that the cold supply was tank fed.


Now I’ve contacted the shower manufacturer and they have said that its fine to install a pump on the cold feed to the shower, my only issue is the cold feed is not direct from the water storage tank. All pump manufactures literature says it should be on its own supply but Its impossible to take a feed direct from the tank, one because its too far away, and secondly, it looks like it holds about 500,000 gallons of water and may take a while to drain and fe-fill.


The cold supply to the shower runs as follows:


40mm copper from water tank running down a riser, tee from 40mm pipe in 22mm feeding the room that I’m working in. The 22mm runs along a wall about 3m feeding 3no wash hand basins, then reduces to 15mm and thats were Ive picked up my a shower supply from (its in a cleaners cupboard that used to have a belfast sink in it, looked nice and easy as the waste and cold supply are already there!). Do you think a pump will run into any problems if the taps are used? Form working in the room for 3 -4 hrs its evident that the taps get used about once every 10 - 15 mins for about 5 - 10 seconds at a time.


Thanks for any advice

Id have wanted to tee off the 22 as soon as it comes off the 40.

Me too, but can't get to the existing pipework to work on it.

Look interesting, but I cant find out from the website how much it boosts the pressure by? Its not the easiest site to navigate is it!

Just wanted to give an update.

I used the forum sponsor 'shower power booster' in the end and it worked perfectly. Time will tell I guess, but I have to say I was really impressed with it. They were not my cheapest option, the cost was £150 per shower (I needed 2 pumps per shower and that gave a 0.8 bar pressure increase). I could have got a single shower pump for around £110 + VAT, but the shower power booster took about 30 mins to fit so it won hands down.

I would definitely recommend them, and would use again if the situation arose. The only negative I could give is that the paper work isn't very clear on how to install and connect them, but I managed to sort it without calling the guy.

Appreciate your informative update that way everyone learns from other peoples experiences (or in my case mistakes lol)....regards Turnpin

It was quite a handy product to discover to be honest, as it gives the option to install any electric shower from a cold water storage tank. And as the flow rates from an electric shower are not that high, you could maybe use it in a situation where its not practical to fit a larger water tank for a power shower.
