Leaky water connector to washing machine

[Stewart]

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.

You need a new flexi pipe as the end sounds knackered. Dont try and bodge it with a few rotations of PTFE tape as even if it does hold it will then wait until the most incovenient moment then slip back and flood your kitchen.

Is there a crack in the threaded ring that is opening up as you tighten it?

Agreed - don't use tape - the thread is there to pull the washer onto the seating. It plays no part in sealing.

It may be worth checking that the Y piece doesn't have a moulding defect on the seating face.

But - get a new hose. Too risky not to.

Further agreement :-)

They're all made down to a price and harden with age (inc the washers) so replacement makes sense. The Y piece could be duff too so inspect and maybe replace.

Recently simplified a 2 appliance hose setup for someone and it took 3 times as long attempting to re-use the old bits, cleaning old washers when they wept, doubling them up and they still wept. Spent a tenner at the local washing m/c shop/repairer and all was sweet.

Suggest you check the customer reviews for that product on the Wickes web page you cited e.g. "Do not buy this product, it is not fit for purpose."

You need a better hose by the sound of it. Not seen this before, is the dishwasher the newer of the two? Brian
