Attach drain hose to smooth nozzle on sink outlet

My galley sink has been leaking into the cupboard for months, and I finally worked out that it was leaking from where the drain hose was attached to the outlet nozzle.

Ah, a simple case of tightening the jubilee clip, I thought.

Seems that there's no way for the jubilee clip to actually get a tight seal around the hose and nozzle, because the nozzle is smooth and tapered meaning that as you tighten the jubilee clip it just slides the hose down the taper, never getting tight.

Besides the fact that I haven't easily found a replacement outlet fitting, I'd quite like to DIY solve this... I tried scoring a ring around the nozzle to give the jubilee clip something to grip to, but no luck there...

Any ideas on how to get a good tight seal between the hose and the nozzle??

Hmm, not sure if there is way that I would be happy with for a long term fix other than replacing for a drain with a parallel nozzle.

In the short term, you could try heating the nozzle and "squeeze" it parallel with a hose clip is my suggestion.
 
Thanks both - I feel a bit vindicated now - I spent about 3 hours trying all kinds of grips and sealants and contortions trying to get this thing to stick!

Penguin is a good tip thanks @pvb - I reckon they'll be able to help!

The sink cutout hole is ~54mm and the hose is 1" OD
 
If the sink fitting is polythene, nothing will stick to it. Wrap a hot wire around it so that it melts into the plastic part way and gives you something to grip the hose.
If its pvc, solvent weld cement will enable you to stick sand to the fat part which will stop the hose sliding off.
Hose drive clips will squash the plastic unless you put a metal insert inside.
 
Feels like some kind of adhesive method is the best temporary fix, until I can find a new attachment!

I reckon self-amalgamating tape might be the easiest bet given the space in which I have to work, although heat shrink is a neat idea if I can get the heat gun into the space....

There's a worrying level of bodging being suggested in this thread! For a tenner, the OP can buy a new waste fitting with a barbed connection for his 1" hose. Fit and forget!

This is the ultimate answer and what I'll aim for :) Penguin are closed for the summer! But I'll keep looking...

I agree with you for some of the suggestions but gluing isn't necessarily bodging. Plumbers use glue for fittings don't they. They fitting was clearly designed to be tapered so there must be a "recommended" way of fitting the pipe. Maybe it's tapered to facilitate the pipe slipping on tightly and it's held by the glue/cement.

No, I reckon it's tapered because it originally had a barbed parallel section on the end, which someone cut off so they could use a 1" hose.
 
TEMPORARY fix while waiting to source replacement :

Small self-tapping screw. Use screw through hose and outlet pipe ... make sure its short so not so much excess thread through into pipe ... then few turns of tape over and then the clip .... the screw will hold the pipe in place ... if it needs it - have two screws - opposing each other ..

Yes, but only similar materials using the correct adhesive. Trying this with different/unknown materials is doomed to failure.

When I had a Moody 28 I had exactly the same problem! I ended up getting a new drain fitting from a caravan shop - not an exact match but worked.

Edit - And I fitted a new hose. I had to do that as I repositioned the water tank more forward to clear the little locker, but that is another story!

Had trouble with mine earlier in year. Got a replacement from ASAP. I think the postage cost more than the fitting!

Its a sink drain. Try it, it will probably be ok. Boat ain't gonna sink if it doesn't work. If it drips, buy a new one.
What happened to the practical boat owner who fixes things.
