Problems connecting washing machine to mains

Oct 26, 2005 11 Replies

So I got my new washing machine delivered yesterday, figured there wouldn't be a problem installing it, since I'd done it before.



However there was a problem, basically when I turned on the mains water went everywhere! The hose didn't seem to fit the outlet tap properly. In my old hose the inside part of the hose was slightly smaller than the diameter of the outlet on the tap and so it fitted inside it and then you screwed the outside of it down to make a seal. However the hose I was supplied with appears to have the both the same size so they just fit flush with each other, with no overlap, you can screw the outside down just the same, but unsuprisingly the water gets out rather readily.



I solved the problem by simply using the hose which was previously connected to the old machine and everything is fine. However I'd like to know why this problem occured, because as from previous posts I'd like to plumb both machines in at the same time, and I can't do that if the hoses don't fit :-(


Maybe the rubber washer was missing on the new pipe, however as you've got it working with the old fittings - I wouldn't worry too much

The way I have it at the moment is only temporary. I intend to reconnect the old machine via a Y-piece to the same tap, however when I tried this then predicably water went everywhere as there wasn't a proper seal.

I remember having similar problems with the new tube on my dishwasher, as the inline filter caused similar problems as yours - you are probably best getting down to wickes / B&Q etc and buying a few new hoses, they are only around a fiver for a pack of 2, you may also need a male to male adapter to work with the y piece - depending on your configuration, I normally take the bits with me, and work out what new bits I need once in the shop!

I assume that you *are* using a proper plumbed-in washing machine tap - and not some adaptor which fits on a normal sink tap?

In that case, it sounds as if either the rubber washer is missing, or isn't thick enough. You can sometimes get a situation where the annular threaded part doesn't screw far enough onto the tap to compress the washer. In this case, you need to fit an additional rubber washer - maybe by taking the one out of the old hose.

Yes, of course. It's a brass fitting which emerges from the floor. There is another one for hot water which is no longer used.

Thanks. I might just buy a couple of new hoses and see how that works out. Another problem is that it was also leaking from the Y-piece connection,

tightened it enough. If the washer is suitably compress the joint shouldn't leak.

Either way, you need to make sure that you have fat enough washers to be compressed enough to make a seal when the nuts are fully tightened. You can get a bit more torque on the nut by using a rag between it and your fingers. Don't use tools on plastic nuts though - you'll break the nuts.

In the half a second I had looking at it before I had to run back to the tap to shut the water off, it appeared to be leaking out of all three joins.

20mm open grommets - the type you use in socket backing boxes - make good substitutes for rubber washers in this application if you can't get a seal.

As you are using main pressure, they need to be bloody tight! - although not recommended I've had to use mole grips in the past to get them tight enough!

Doing them up too tight destroys the washer though, the sealing part of the fitting is quite thin so it just cuts into the edge. Even more of a problem on those plastic Y-adapters I've found. Better to use thicker washers than do it up too tight.
