Setting off tomorrow for our first outing in the Hymer 544, heading for Porthmadoc for a couple of nights.
Got things ready today and found a leak of water into the cutlery tray beneath the sink. It seems to be coming from the waste trap which has a twist off bottom. There seems to be a rubber gasket that looks sound so cleaned and put back - still leaks. then I put some plumbers mate on the seal - still leaks. So I cleaned it all off and tried silicone bathroom sealant - guess what - still leaks. Grrrrrrr
Anyone had a similar problem and how did you resolve it please.

Funnily enough, saw what might be exactly your problem at Chester this weekend

Mr and Mrs Mousy had a similar leak, turned out they had a hairline crack across the bit you can remove

Terry fixed it with sika seal, smeared some on both sides and left to go off

Hopefully yours is that simple (y)

Not sure if Terry has been carrying out secret repairs as I am pleased to say we have not had this problem (yet). @Terry

I reckon it split due to freezing. You can get new ones here-

When mine was leaking into the drawer, I did exactly as you did, even bought the replacement trap.

Didn't solve the problem, turned out mine was leaking at the plughole.

Thin bead of sealant before resitting the plug worked for me.

Thanks. I`ll try that when we return, until then we`ll be mopping out the tray every day !
Hi Just as a temp measure try removing trap base and putting some cling film over hole then screwing trap onto it ;) don't pull CF too tight

Don't worry, it was our waste cap that split and leaked, @DavidG58 had everything right just the wrong van.

Still no leak, thanks again @Terry

well spotted all, not even a Hymer, I blame the excitement of Chester, I was still infused with it last night

hope you get sorted Figaro

I cured the exact same problem by smearing the rubber gasket with vaseline, still sound a year later.
Same problem in the washroom I thought until retightened the trap and the whole of the basin turned with it!!!
Learnt alot fitting a new one!

It might not be the cap. We had a similar problem with ours - Smev sink in a Burstner and (after trying all sorts like you with the cap) it turned out to be the seal to the sink itself.
If yours is the same, unscrew the bolt which holds the plughole and the underneath together, pull apart just sufficiently to be able to clean the mating surfaces up. Put a new bead of sealant on top of the trap then reassemble everything.
Worked for me (y)

Thanks for all the useful replies.
We had a great few days for our first trip in the MH to Porthmadoc, helped by the brilliant weather !
I`ll have a go at the trap repair over the weekend
