Shower pump location / type

marky9074 · 9 Oct 2007

Hi there,

Just ripped out my bathroom, and have two 22mm (I guess) pipes from the hot and cold side of the bath. Now, it's a gravity fed system, and I purchased a Grohe 2000 shower as it stated that it would work on a LP system. But I also got the Tarantofill kit which quote that it is HP only, so I am at a loss as to if it will work on a gravity fed system or not....probably not!

So, ideally what I want to know is where you professionals install a pump in this situation? I understand that for under the bath installs a low voltage system is used? Where would you put a normal pump...in the loft? If so have to run pipework, back up and down again....?

Here is a picture:

Any help, or suggestions on make/model much appreciated..

Cheers,

Mark

> a low voltage system is used?

your pump can go under bath.

A normal pump or low voltage pump?

Cheers for that. And can I just go pipes to pump, pump to grohe 2000, no special valves or nothing? (sorry if that sounds dumb, just reading too many threads on here...)

just stick two isolation valves in on the feed to pump and two non return valves on the pump outlet side.

Any suggestions on pump make? I did use a screwfix jobbie before on the ensuite shower.....but man that is noisy...

Its exclusively for the shower/tarantofill so doesnt need to be massive pressure.

Another silly question. Can I use flexible hosing to pipe most of this in? Just thinking of the location of the pump under the bath, and the fact I havent decided or ordered a bath yet.....

Would hate to have it all fitted and not left myself enough room. Just thinking that it might be handy to be able to move the pump a few cm either way....

Seems OK I guess...

Still sceptical about being enough space at the waste end.....

put pump at over end.
run the two feeds two the over end on top or under floor then your outlets to the taps.

Hmmm, that will be a right PITA for me. Maybe get a double ended bath with the waste in the middle? Would that give me enough room at that end...?

marky9074 · 12 Oct 2007

Remember also that I have a tarantofill as well, so no taps....I think there is enough space at the other end?

marky9074 · 13 Oct 2007

Anyone? Seems like there is 200mm clearance under the bath (enough for the pump). and with no taps at that end clearance for the pipes...
