Hi, new to the site, im looking for some advise with regards to the cold feed needed for a washing machine, basically I recently had a friend/retied ex plumber move my washing machine to a new location in the house he has plumbed into an upstairs cold feed that leads to the loft tank the machine seems to be working fine but I have been told it should really be mains fed? We are due to get a new machine soon and it is a cold feed only so im a little worried this could be a problem, the tank is about 16ft above the machine.
Would be grateful for all advice .
