I have had 2 different plumbers round and both have told me conflicting information.
Basically, we have installed a thermostatic mixer shower in the upstairs bathroom. We have mains cold water feed and hot water from a tank in the airing cupboard. The problem we are having is that the cold water pressure is much higher than the hot water pressure. As such the shower is running freezing cold and running a bath takes so long because we have to have the cold tap on low so we get enough hot running through, but of course this decreases the water flow and filling the bath takes for ever.
One plumber told us to fit a pump at the base of our hot water tank to increase the pressure, but the other plumber said this will make no difference and that basically we have the wrong type of plumbing for any shower other than an electric one.
We live in a council house and have been told that we will never be allowed to buy it. Hence, we do not want to spend lots of money on an electric shower plus the plumbing and electrician costs.
We are desperate- Does anyone have any kind of solution for this problem. Some sites have suggested fitting a pressure reduction valve to the cold pipe but I'm not convinced this will work either.
