Adapting waste water outlet


Hi, I've got a new Starcraft and it comes with two waste water outlets for the 2 sinks, plus a waste water outlet for the washing machine. At the moment I have the waste water pipe attached so the two sinks flow into that, but the washing machine just drains onto the floor. I want to combine them. The Jayco guys gave me an adapter, but obviously I need additional piping because of the difference in diameter. And I'm guessing hose clip bolts to tighten them? I'll post up some photos shortly, just trying to figure out to do it! Photobucket isn't working.

 

So if you look at the first photo, basically I want these three outlets feeding into one waste water hose, outlests are the two white ones in the foreground and the larger diameter one (washing machine) in the background.

My old Jayco has two waste water outlets.  One from the sink & the other from the ensuite (Vanity sink & Shower).

If I join them into one using an adaptor like the one that you have then on occasion there is a back up into the shower floor.  This can easily be fixed using an anti backflow device like a Hepvo valve in the vanity feed line.  I don't bother & just use two waste hoses.

On the rare occasion where my hoses are not long enough I use the 2 to 1 adaptor like yours at the end of the two hoses & use my back up 3rd hose to extend the outlets.  Any back up is accommodated in the extra length.

I do have the ability to join the two near the van, by using an adaptor like yours but with 1.5m lengths connecting to the van outlets.  I can then join my 3 pipes together.  Can't remember ever having to do so over 20 years of vanning.

As it is rarely used, I only connect up the washing machine when it is needed, using the back up third hose.  If anything is going to cause a back up it's the washer.

I never use any clamps etc on the joins.

 

In your case I would fit some sort of adaptor to make all outlets the same size.

 

The outside diameter of my outlets is 27mm (I suppose it is 30mm conduit) which is the inside diameter of my waste hoses.  So they just slide on neatly & never come off even without clamps.  Where I need to join my pipes I just use small pieces of 30mm conduit.  I carry a full length in the open van chassis.

 

If you really want to have only one waste hose then after making all outlets the same diameter, make up 3 to 1 adaptor using 3 (at least 1 meter) lengths of waste pipe that join using elbows & T pieces etc, into one outlet pipe.  I wouldn't bother.

BTW, I use smooth sided hose & not the corrugated stuff that is popular these days.  It's easier to clean.  Mine has lasted for 20 years too.

 

Sorry for the long winded reply.

Hi zed,

Welcome to the miriad of combinations known as the Jayco water outlet. biggrin

My Siverline has a grey water tank and a washing machine and when I first got my van I just connected the hoses together and use a 30 mm black hose. (27mm ID)

This caused massive grief as the washing machine water backed up and ran put on the bathroom floor

The top loading washing machine requires a 38 mm discharge hose.

I solved the problem by linking the two outlets with fittings and then bought 38mm air seeder hose from a rural supplier and used that as the hose to the drain.

You may be able to do something similar by using the present adapter and then buying adapters to connect the washing machine drain all as one rather than use two hoses.

The air seeder hose is smooth inside which is an advantage but with the top loader machine anything smaller than 38 mm may cause a flood of sorts due to water backing up.

Air seeder hose from a rural supply shop is generally a fair bit cheaper than the hose you buy in a caravan shop.

I will try to resize a pic and upload it..

Here is my connection.

I save having to carry two different size hoses as Jayco dealer suggested.

We have a Jayco Silverline, and had the same problem. The issue is that the outlet hose from the washing machine itself, requires an open, or vented outlet in the form of a stack pipe. The purpose of this is to prevent a syphon occurring, and stop you loosing all your water from the wash machine during its cycles. The concequence of this is that the outlet hose must not have any restrictions because if there is, you will end up with a mess in the van. This explains the separate outlet, and the extra bigger diameter hose you have to carry.
I have all of my waste, including the wash machine going into the grey water tank, to avoid an overflow of the stack tube, I have made up a balance tank out of 100mm PVC pipe, capped off, and mounted under the van, the wash machine drains into this, and if there is any slowing of the flow, the water can back up into the balance tank, if this tank gets full, it is open at the top and will flow onto the ground, before it overflows inside the van. So far it works well. I can supply more info if required. If you are intending to just stay at caravan parks, and space is not an issue, purchasing the correct hose for the wash machine may be easier

We use a grey box purchased from the bargain shop with a threaded fitting sealed in the side as close to the bottom as possible. Our sullage pipe is then fitted to it. There can be no water coming back up as the box is only placed under the outlet pipes and not physically connected to the van. We did this on the recommendation of a Jayco salesmen. Geoff and Bev
