Hi, I have just refitted our existing en-suite shower cubicle with a shower that now needs a shower booster pump fitted and possibly a SURREY CYLINDER FLANGE to a gravity fed system with hot water tank. The house is twelve years old with the hot water tank in the upstairs airing cupboard. I would be grateful if someone could give me an idea of cost for supply and fit (Twin 1.5 Bar pump), and for cost of fitting only .
