Hi, I'm trying to plumb in a washing machine and dishwasher from the same c old feed using a y piece very similar to this one
The problem is that I keep getting a leak from the connection between the h ose to the washing machine and the y piece.
For ages, I couldn't work out why. I was doing it up tight (perhaps too tig ht, out of desperation) and it seemed to make a good seal when tested under the tap. Then I realised that once I connect it to the cold feed pipe, the pressure of the water is causing the connector in the hose to jump off the thread of the y piece. I can make it do the same using my hands if I give a good tug. Has anyone else had this?
The hose running to the dishwasher tightens, seals and remains sealed - but it looks as if its connector's internal thread diameter is ~0.5mm less tha n that of the leaky hose. Neither hose leaks if connected directly to the m etal cold feed pipe. Is there any way to make it stay sealed or should I ju st go buy another pipe?
Thanks in advance.
