I went to a job today, following a visit from a retailer ( not sure which one didnt ask) who had installed a washing machine, on installing the machine he diagnosed insufficient water inlet flow and advised calling a plumber ie me. The existing cold feed was run under a concrete floor in 15mm copper and unprotected, I disconnected this pipe and capped under the sink as I was unhappy with the unprotected pipework. I ran a new cold feed from the bathroom upstairs to fix the insufficient flow issue. Problem solved you would have thought however on turning on the washing machine (there was no longer a flow problem) after approx 5 mins the machine began to vibrate badly and make a banging noise. I advised calling the retailer or manufacturer as I do not deal with washing machines other than installation pipework and waste pipework. I suspected that the transit bolts had not been removed? has anyone got any experience of washing machines that could shed any light on this, its playing on my mind, I hate not having the answers.
