Hi Folks. No, I don't want recommendations for a good urologist or gastro surgeon thanks.

What I want is some advice on cleaning out the waste water PVC piping in my van. The sink is the highest point, then the hand basin and finally the shower.

We get a terrible smell out of the handbasin which is obvious less used than the sink and usually its just cold water and used toothpaste going down it.

Have read plenty of past advice on the many previous posts here, but seems to be about the sullage pipes and I run plenty of hot water and clean the connection end out with a brush.

Currently I bung up the outlet with rag and then tip a little bit of Draino down the sink and handbasin plugs.

Any better suggestions please??

Jim - Bev is really upset with you !! She gets all her chest hair waxed off once a week LOL (and Ive stopped using Bobby pins now and just let it all blow in the breeze)

Jules - I hope that's not the rear end of Billeee we're seeing there is it - his plumbing looks like it has a major crack in it hahaha.......perhaps a bit of bog (aka fiberglass) will fill it in

And John - thanks for that, I will give it a try. We've had this terrible smell before and blamed the toilet - but I keep it very clean and always give it a careful "sniff" test to make sure the cassette and where it sits is always fresh smelling. We seldom have any solid waste in it as normally we are house farm sitting, in a CP or if free camping, a 12" hole in the ground or the local public toilets

All the smell was in fact coming up from the handbasin (presumably because it is the last inlet in the plumbing). The Draino certainly did the job (only had it in there for 30 mins as per the bottle instructions) and no more smell. We also hooked out Bevs hair and the slime that had gathered where the sullage pipe is screwed on and washed out the pipes.

The other problem is the caravan is on a slight lean at the farm we are staying at (despite wheel chokes on that side) - this allows the water to sit in the lowest part of the pipe. We leave here (thank god) this Sunday. I will stop in a metalled rest area and with the van leaning the other way slightly, run some boiling water down the sink and hopefully that will get the residue out. I don't want to turn up at Surfils place this Sunday with dirty pipes :)

Next time I will try John and Jules recipes.

Watch out the draino doesn't set hard in S bend , Just recently my friend put draino down his sink over night and set hard and had to buy a new s bend .

Yes Bruce - we only allow clean drains here at Gabbadah (sufil's) - see you Sunday!

Our van had a straight thru pipe so I put a S trap under our wash basin for this very reason. Works a treat.

I may be wrong, but I put a cup of bleach down each drain every few months. Stops smells, kills bugs and we have never had an issue.

Cheers

I break a odour B gone tablet used for toilet cassette leave a piece in the sink after washing up and a piece in the hand basin it takes ages to dissolve, it cleans out the pipes as you wash your hands or washing the vegetables in the sink.
Too easy
