I have just moved house and my dishwasher and washing machine (both cold
fill only) are plumbed into the same water supply. The two hoses are
connected with a Y connector.
Last week while the washing machine was on water was gushing out of the Y
connector which had split. I duly bought a new Y connector and all was well
until today when the Y connector split again so I can't use either
Can anyone suggest a remedy to this problem or do I need a qualified
I had more or less the same set-up at my other house except that the washing
machine was hot and cold fill and never had these problems. The water hose
on the new dishwasher is a rigid hose while my old dishwasher had the same
hose as the washing machine. I am wondering whether I may have a water
Can you get at the (presumably copper) cold water pipe? If so, consider
fitting an additional outlet on the pipe. You can buy outlets that are
dead easy for anyone to fit and don't even need the water turning off. A
very, very simple DIY job. They clamp around the pipe and then you turn
one part of it to make the connection - all without spilling a drop.
It does sound like either very bad luck or very high water pressure.
If you have bought the Y connectors from the same place, take them back
and tell them of the problem because it must be the connectors that are
faulty. If the water pressure was high enough to split a Y connector, it
would also split the flexible hose, because the Y connectors should be
stronger than the hose..
As Harry wrote, they shouldn't fail like that. I've never heard of it
before and I know loads of people that use them. I've never seen a brass
I've known plenty that leak - the strain of two fairly still hoses
pulling, via the Y adapter, on the connection point is a bit much, IMHO.
Hence the suggestion of adding another outlet.
It is possible to produce an alternative solution, without altering the
existing plumbing. You could buy an extra hose and connect that to the
outlet. Buy an extra (eg compression) outlet and connect that to the
other end of the hose. Connect a short length of pipe to that outlet and
put two outlets on that - one at the end of the pipe and one at the
middle. Bingo, two outlets and loads of hose length to pull the machines
right out to clean behind them, without having to disconnect anything.
Great for when you have stacked appliances.
I have never seen a brass one, or found the need for one, the plastic
ones should easily stand mains water pressure without splitting. Where
did you buy the Y adaptors from, was it a national chain, or just a
small shop? If their Y adaptors are failing, I am sure that they would
want to know, as they could be liable for any resulting damage caused by
such a fault. Are you sure it was a split in the plastic, and not due to
a missing or incorrectly fitted rubber washer, either in the end of the
hoses, or between the Y connector and the incoming water supply?
I bought them from Dyas, the washers looked OK and the hoses are fine. I
think that you may be right that the Y connectors are faulty, I shall
return them tomorrow.
I have put a new Y connector on so I can only keep my fingers crossed that
it doesn't happen again.
Thank you for your input.
Could easily be a split, i bought a waste trap from a plumbing type place a
few years ago, fitted it and after a week of use noticed it dumped half the
water that went down it onto the floor,
looked at it and where it had been molded, the mold line was very very weak,
and almost see-through where it haddnt split already, prolly from a worn
took it back and looked at hte others on the shelf, and they were all the
same, see throguh line where the mold line should be.
seems those traps were from china, and had been made for half a penny each
most likely, hence quality controll was non existant,
but i'd go with the others suggestions, put another outlet on the copper
pipe, that way you can isolate each machine in turn if the need arises.
