Morphboy13 Posted April 25, 2019 Share Posted April 25, 2019 Hi everyone. I'm new here and I hope someone can give me some advice on what may well be a simple matter on my 1999 hymer b584. The pipe leading left under the left sink (towards the hob drainage pipe) appears to have broken. As you'll see from my photo it's an even break. This is causing water to leak out into the cutlery drawer when draining either of the sinks. There isn't a blockage leading from the right sink towards the grey waste because I've tested it with hot water and that pipe gets hot as far as I can feel and the shower and bathroom drain fine (which in this model are nearer the grey waste tank). I'm therefore confident that repairing the break will solve the problem. My question is simply this. What should I use to fix the pipe? I'm thinking some sort of super glue then a waterproof tape wrapped round it. Your advice is appreciated. Link to comment Share on other sites More sharing options...
Dickybeau Posted April 25, 2019 Share Posted April 25, 2019 Gorilla Glue then waterproof tape? ALDI or Lidl have it on sale. Difficulty you have will be to find a glue that remains waterproof. The other ‘glue’ to check out is Sugru which you might be able to use instead of tape https://www.amazon.co.uk/s?k=sugru&hvadid=80333100030498&hvbmt=be&hvdev=t&hvqmt=e&tag=mh0a9-21&ref=pd_sl_8ynbgj29yp_e Link to comment Share on other sites More sharing options...
Billggski Posted April 25, 2019 Share Posted April 25, 2019 Rather than trying to glue two flat surfaces together, which could undo with vibration. Can you insert a tube of the right diameter into your remaining waste inlet and then fasten the pipe to that? I guess the bore doesn't need to be that big.

Derek Uzzell Posted April 25, 2019 Share Posted April 25, 2019 Gorilla markets “Waterproof Patch & Seal Tape” https://www.ebay.co.uk/p/Gorilla-Waterproof-Patch-Seal-Tape-Size-3m-X-100mm/4031283491?iid=392266829313 but I echo Billggski’s suggestion to use a tube. If a tube were inserted into the black broken-off part and the tube extended into the black thing (on the right of the photo) that it’s broken off from, that should at least stabilise the two parts’ connection before gluing/taping them. (I’m guessing that the black thing on the right that the blue pipe was attached to is a waste-trap for the kitchen sinks. Such traps are marketed (examples here) https://tinyurl.com/y3res9ck but I don’t know if one suitable for a 1999 Hymer motorhome would still be obtainable.)

laimeduck Posted April 25, 2019 Share Posted April 25, 2019 Just a thought? I agree with the internal pipe idea, but it might be worth also using plastic pipe weld to join the broken pipe, rather than ordinary glue. Plastic pipe weld actually "melts" the plastic so could form a waterproof seal while ordinary glue simply bridges the two surfaces. Obviously it would be sensible to test that pipe weld will work on that particular type of plastic with a dab on the pipe body to see if it "melts" it before commencing. This sort of thing https://tinyurl.com/yy68rk7c Link to comment Share on other sites More sharing options...
Morphboy13 Posted April 25, 2019 Author Share Posted April 25, 2019 This is fantastic help guys. I'll take all of your comments on board and try a repair this weekend. Much appreciated. Link to comment Share on other sites More sharing options...
ColinM50 Posted April 25, 2019 Share Posted April 25, 2019 Think I'd probably go the other way and look to find a plumbing connector that will fit over this piece and then fix it with solvent weld glue. Have a measure of the pipe and pop in to B&Q and find a matching connector. I can't be sure but looking at that I reckon a 40mm waste connector would fit. If you don't have one, a cheap vernier gauge will help measure it or take the broken bit off the blue pipe and take it with you. By fixing a pipe on the outside of the existing, you won't restrict the flow. Link to comment Share on other sites More sharing options...
thebishbus Posted April 25, 2019 Share Posted April 25, 2019 That connection is just the drain connection for spillage in the hob unit. The black part attached ( just stuck on ) to the waste connector is 28 mm in diameter. If you did not want to try to repair the broken bit, you could use a length of 28 mm bore hose, angled up towards the hob, and push the blue hose down inside it. Brian B.

Guest pelmetman Posted April 25, 2019 Share Posted April 25, 2019 My old mans hardly used 3 year old Hymer had the exact same problem ;-) ....... At first we couldn't work out why his cutlery draw was filling with water :-S ...... Solved the problem with one of those clip over wine stoppers :D ....... Progress eh? (lol) ...........

Morphboy13 Posted April 25, 2019 Author Share Posted April 25, 2019 Pelmetman.....lol (lol) Ooh....I like Brian's idea. I hadn't realised that the broken bit can be separated from the sink fitment. That being the case the bore hose sounds like a simple fix. Once again.... amazing help everyone. I'll be asking more stuff on here in the future cos I really need to learn how to fix things myself as my big old lad reaches old age. ;-) Link to comment Share on other sites More sharing options...
