So i’m no plumber but my father was so I know a little about plumbing.
What I actually didn’t know was that in the UK you can boost the inbound water mains to 12litres per minute (according to WRAS) directly off the mains. I thought any pump would have to be fed from the cold water storage tank.
So with a small amount of research I’ve found:
If you’ve got access to the right tools and feel comfortable with the install then its fairly straight forward. The main bit I would recommend before purchasing is to make sure your cold water stop tap works or check if you have an external one (that potentially cuts supply to multiple residence). I actually had one that cut supply to about 10 houses. We tried to freeze the pipe before hand but it proved difficult with the inbound pipe being lead so we ended up giving notice to the other houses and cutting the supply to install the new stop tap. The best bit was the external stop tap was on someones drive with the opening flap being under their car so even more fun ensued..
So when I get a chance I think it’ll be time to grab one of these and give it a shot. Should give some much needed pressure to the electric shower so as to not give people cold shocks when the washing machine / dishwasher / kitchen tap is used! Plus you get a nice clean feeling when the shower has some omph to it!
Here a diagram to visualise the install with:
