Hi all,
I've been reading the archive on google with interest on shows and pumps as I'm about to start a bathroom project. I couldn't find a query similar to mine so I'm after a little advice.
I'm going to replace a cold feed shower with a thermostatic mixer shower. I have no problems with mains cold pressure, although I don't know what the exact pressure is. I only need to turn the cold tap on the bath to get a good strong flow of water. The hot is fed from a tank on the landing.
When I had a company out to give me a quote on doing the bathroom for me they said that because the shower head is less than 1 meter below the cold tank a pump would need to be fitted. Now I can't quite see this as the cold pressure is fine but I can understand pumping the hot feed to increase the pressure and therefore making the mix a little more even. Also the cold tank is directly above the hot tank with more than 1 meter between them.
Can anybody give me some advice, is it possible to get a hot only pump? If I was to pump the hot and cold with say a 1.5 bar pump and the cold was already around this pressure would I end up with 3 bar on the cold pipe? Anybody had problems taking the shower feed off the hot and cold pipework to the bath? as the tanks are along the landing and it's not going to be easy to run new pipes.
Sorry if the questions seem silly, I've read too much and I'm now very confused.
