shower pumps....
Hi all.
I've a en-suite that has a power shower fed from a pump that sits next to the hot water cylinder. The shower in the bathroom is a mixer type
that isn't powered. I'm putting a new shower in and would like it to be powered. The pipework for this shower goes into the loft then down
into the bathroom.
Option 1:
Could I fit a pump in the loft, a twin feed pump inline? Once it senses flow it'll spring into life, any issues with it being above the hot
water cylinder?
Option 2:
Could I use one pump to feed both showers, basically a t feed off the hot and cold outlet, piped to both showers? I guess a 3bar pump would provide
enough flow even if both are being used at once?
Option 3:
a second pump to sit next to the existing pump sharing the feed via T pieces so both pumps could run off the same source?
Have I missed anything?

You can get a single pump which has the duty to run two showers concurrently I have one got is at b&q.
From memory I believe they have to be below or at the same height and as close as possible to the bottom of the cylinder

Franky,
I've got two twin impeller pumps brand new sitting about.
I bought them to use in my house and even though they were fitted they only had one hour or so use before we changed our minds and went down a
different route.
Very cheap if you're interested.
I only live at Louth not far from you. U2U me if you are interested - like wise any one else who wants them.

Shower pumps push dont pull so if there is an air lock youd be snookered. I suppose if you had enough head feeding the hw cylinder it should be OK so
your cold tank would have to be a fair distance above the pump. But I'd be more inclined to leave it where its at option 2 I would think
best.
Cheers,
Bob

As above..these pumps hate air... so they need to be as close to the bottom of the HW cylinder as possible.
If you intend to run two showers you may have issues with flow unless the pump is fed correctly using a surrey type flange in the hot water cylinder.
Should be non restricted 22mm all the way from inside the tank to the pump.

the current pump already has it, seems like the best way is to get a 3.0bar pump and feed both off that. Its not often that both will be in use at
the same time.

Just to show my stupidity, what's a shower pump and why do you need one?
Keep in mind I'm in the States.

Texan it's a expensive noisy unreliable pump that is required over here to boost ahower performance due to the vast number of houses still using
Stone Age plumbing.

OK. It's to counter low water pressure.
Sometimes it pays to live in a younger country. There's not all that old stuff hanging around

I have got 2 central heating pumps powering my shower , they work a treat and hardly make any noise just need to get around to fitting a flow switch
to replace the pull cord that is presently controlling them.
