Best Sullage Pipe to Purchase

KFT · Guru

G'day,

I would say it depends on the size of the waste outlet plumbing. Mine is 40mm and I use a 40mm plastic drain hose and have no issues with it backing up or clogging. I use the joinable pool hose from big w or bunnings because I can just put together as many sections as I need for the job.

Dont make the mistake of getting a hose that is smaller than your drain outlet because that will cause backup issues.

I have never liked the idea of the layflat especially where it is a gravity feed and not under pressure.

Caravans plus have smooth bore waste hose in a couple of sizes, don't waste your money on flat waste hose.

From experience, (not in a RV), layflat rubber hoses are not much good without pressure, pushing the water

The larger internal size hose, is always more efficient, than the smaller size hose

My grey water hose is the corrugated outside, and smooth bore inside, you buy it from the caravan/camping shops

It is 25 mm inside bore, as that is the size of all the other internal grey water hoses, and valve size, on my RV

I have never had problems with blockages

But...

I clean the dishes with paper towels, before I wash the dishes, so no solids go down the sink

A friend had one of those flat hoses on a reel - fantastic as far as storage went BUT where it attached to the connectors, it split & was impossible to repair.
Over priced junk!
Conventional sullage hose can be rolled into a smallish bag made from shade cloth (about $20 from caravan parts stores).

Tried the original black convoluted stuff which came with van, it did not last long due to UV degradation.
Bought the u-beaut smooth interior superior quality convoluted stuff, from a show special, lasted a tad longer.
Now have some clear reinforced pressure hose for chemical use from an irrigation supplies shop in Roma to make a new yoke from 2 outlets to one run, HEAPS better, and so have replaced all with same.
Yes a tad heavier, but heaps easier to use and still fits into the three x 6 metre long PVC holders under the length of the van. Very easy run due to smooth inside, connectors are all 1" black poly nuts and tails.

Thanks fellas you have confirmed my preconceived ideas. When and if I finally get to collect van my from NSW I will source the size hose to match the existing plumbing outlets.

40mm pool hose. We have a 10mt and several smaller ones we can join.

Never been a problem using as normal or with washing machine.

Much better than the smaller gauge ones they supply with vans.

I run the hose through them when packing up.

Don't be conned into buying a special purple coloured hose for your caravan sullage. Plumbing codes referring to purple coloured pipe for sullage or effluent do not apply to caravan sullage water.

Part of our black sullage pipe was turned into an elliptical shape over a couple of very hot days (40+C) when we stayed at Edithburgh SA in 2019. The pipe was laying on greenish grass too. Luckily we have not suffered any blockages with the elliptical profiled pipe section so far. Sometimes I think about what I can do to make it circular again.

I have the flat on a reel water and sullage hoses and have been using them for over 5 years now. Whilst nothing is perfect and they have a couple of issues I have found them very good and easy to store. The sullage hose flows slowly but given I have a 95 litre grey water tank it doesn't cause an issue and the ease of winding them up and storage makes them a winner in my book. My 2 gripes with them is you are stuck with a fixed length of hose so often you are trying to lose the excess under the van or elsewhere, and dirt on the hoses binds up the reels which is fixed with a hose off under the tap and a spray of silicone lubricant. The other issue with the sullage hose is that they do tend to be a bit loose on the waste pipe but easily solved with a Utilux hose clamp.

IMO those cam lock fittings could cause a restriction as it fitts inside the pipe. I bought poly hose that slides over the outlet. Use a butterfly hose to clamp it to the outlet. .

I ditched that dreadful common drainage hose, I recon figured the entire drainage system setting up 2 exit points 1 in the standard position and the other rear off side, using 25mm pressure pvc pipe available from the big green shed, i have half a dozen meter lengths spare of the same pipe along with a variety of joiners straight, 45, 90 degree which I can run to the drain point closest to the exit point.

The "camlock" fittings are utilised in fire fighting vehicles and hoses as they present un-interupted flow of fluid - female spiggot end retains outlet bore, camlock hose attachment retains bore size, sullage hose larger bore size than original bore.
