I'm thinking of installing a Stuart Turner monsoon booster pump to improve the hot water pressure in my parents house. The problem is that I can't work out which pressure to go for - they come in 1, 2, 3 and 4 bar versions with a couple in between as well. The 3 bar version seems to be the most common one fitted but as they're not cheap I don't want to get it wrong. So what's the best way to work out which pressure to go for?

One thought was to measure the cold water pressure and match the hot water to that. It's not particularly important to match them though as I'll probably get a twin impeller pump and boost the cold water supply to the shower at the same time (the cold feed to the shower comes from a header tank, all other cold water outlets are mains fed). Can anyone offer any advice?

In a standard slide rail based shower, 1.5 bar Is an alright shower, 3bar is a brilliant strong shower. Depends how you like them.

You've also got to bare in mind the size of pump and the size of hot water cylinder/ cold water storage tank. You could pump them dry.

This! I've got a lovely powerful shower at home, proper monsoon stylee - but if I'm in it for more than about 10 minutes (it's so nice I just like staying in there!) then suddenly the cold water runs out (not the hot for some reason) and you can hear everything gurling in the attic, and the taps don't work/toilet won't flush etc for half an hour!

Plumbed incorrectly. Hot should ALWAYS fail before cold. Incidentally air in pump impellers DRASTICALLY reduces their life.

me thinks you need to upgrade the tank size in the loft..... maybe double it or just put a time switch on the pump so it cuts off after about 6 minutes....
