I had never liked the existing water distribution system in the house which used a noisy shower pump (not great at 3 in the morning !). Dave (Tap N Flow) checked our mains pressure & suggested changing the system to a Fabdec unvented cylinder (which is essentially maintenance free & does away with the pump). We agreed & he started the job a few days later. Despite working in a confined space (the old airing cupboard for the cylinder & the garage roof space for the discharge pipe), Dave's workmanship is exemplary & he worked in a quiet, efficient & tidy manner to modify the system & replace the old hot water cylinder with the new Fabdec unit. He kept me informed throughout & did a great job of explaining to me the new piping layout & how to isolate the various water systems (hopefully won't ever be necessary). We had one hiccup (nothing to do with Dave) - the factory-installed pressure & temperature relief valve on the cylinder was faulty so there was a couple of days delay whilst a new valve was shipped out. Once it arrived, it was a quick couple of hours & the system was working & tested...& it is great to have silence rather than the whirring of a noisy pump whenever you turn on a tap ! Dave is a very knowledgeable & experienced tradesman with a great customer manner. I can thoroughly recommend him & wouldn't hesitate to use him again.
