Grey water drain-off taps. (1 Viewer)

[VandM]

Morning folks.

Are most/all grey water tank drain off taps on the off (road) side of UK motorhomes?
We're designing a grey water point and trying to decide if it's better as drive-over type or off to one side with a short length of pipe to attach to the drain off tap.

Mines on the off side just inside of the van sides easy to get to.

but it can be moved anywhere and any direction on the underside including a drain off tap on either side If required.

if it’s a plastic pipe it can be added to or moved. A tap both sides requires a section of pipe one tee and a drain valve.

Had several Autotrails and they were all on the offside.
My current German built van is also on the UK offside.
We did once have an Eldiss and that had the waste right in the centre of the van with a long lever to pull it open !! Pain in the a**.

Our Swift has the drain tap just behind the nearside wheel. It's quite easy to get at but I got a screw in fitting from the local plumbers merchant and attach a washing machine flexible drain pipe if I can't get near enough a drain point.
On balance the pipe on the UK off-side would be better as the existing position is into our normal relaxation area, on the vans nearside. If your hab door is UK offside then maybe fitting the drain to the nearside would be better.

Doesn't really matter our Hymer its on the UK nearside on the last Hymer it was on the UK offside.

UK Nearside. (But I'm capable of turning round and reversing )

I would think that a drive-over must be the best option as it is the most flexible.

Ours is on the near side - about 40 cm under from the edge of the van - with a lever on the van skirting. We cant reach to put a pipe onto it.
So a drive over would be best for us.

2018 German RHD Hymer
Drain is on the right side
(as is the hab door and the water and the electricity )

Old van was a Euromobil, drain was in the centre

I'd have thought a drive over would be best, either with a centre gully, or better still, build it on a slope to one corner where you put the drain.

What you really need to discourage is people (accidently, or otherwise) dumping black tanks in the same place.

My 2009 EuraMobil has the drain on the nearside just in front of the rear wheel. I modified the original with a flap fitted in to the skirt so I no longer have to lie on the ground to get at the connector for the pipe which was a right pain to locate and connect. My hot melt glue gun came in useful when fitting the bayonet style connector into the flap unit I bought (grey in colour to suit the skirt). Has served me well for a coupe of years now and uses 40mm flexible pipe so a fast drain. The valve itself is just inside the nearside locker so no chance of accidental operation. The flexible pipe means I do not have to locate the drain over the sump into which you discharge. At home I park next to a storm drain in the road near the house which inconveniences nobody, I hope.

If the majority of UK vans have an offside drain, why do most sites that don't have a proper drive-over fit the manhole close to the kerb of the MH service point? It invariably means turning the van an approaching the wrong way round their one-way systems.

 

[emjaiuk]

Assuming I've understood the OP correctly and they are asking for advice on the construction of a waste dump point, personally I think drive over is best if properly designed. A full width grid means it doesn't matter where on a MH the outlet is. The sloping area which guides the water to the grid should be wide enough to allow for splashing, campers with horizontal outlets need a largish area for waste discharge, on initial opening the jet of water can travel quite far before it eases back to a dribble. The channel under the grid should have a reasonable fall towards the actual drain to avoid pools of stagnant water. A floor washdown hose would be nice providing people use it.
A nice enquiry, I've seen some ridiculous waste areas in places, La Mailleraye? Good luck with your project

Agree - I prefer a big grid to drive over as our dump point is central with a lever pulled from the UK nearside. I need to modify it to put a hose attachment on to give the option of either as it's a pain on some sites (I've resorted to parking over a dip in the rutted approach road close to the waste point to give some extra ground clearance and using a collapsable bucket on one CL).

Now thinking about what I wrote it seems a good idea now to add an outlet on the other side .
I have the pipe. And the rest would be about £25.85

and as the system we have is all plastic it’s an easy project.

just looked there is another take off for waste the opposite side to the waste valve so a short length of pipe an elbow and tap And screw connection. All on eBay.

now on my todo list.

Morning folks.

We're designing a grey water point and trying to decide if it's better as drive-over type or off to one side with a short length of pipe to attach to the drain off tap.

On my Compass (Elddis) it’s on the offside just behind the rear wheel. Or at least it was until it dropped off just as we were running to catch the Isle of Wight ferry. The tap twisting motion was being transferred to the tank fitting which came off. I had to fabricate a better arrangement and it’s fine now

On my last rollerteam it was an 80l tank directly in the centre at the very rear most point. Black tank was immediately behind the drivers rear wheel.

They are on both sides but as long as the hole is at least a metre away from obstructions and there is space to reverse over, there should not be a problem.

Just remember the old saying about 'pleasing all of the people, all of the time' and you'll be okay....... Good Luck!

 

[the1andonly]

Mine was on drivers side but moved to centre hiding behind skirt can add an extension and elbow to left or right with ability to add upto 5m extensions.

I guess it depends on how you use your van. Ours has the central dump point with long handle.

Was a PITA having to bump up kerbs to get over the street drain, now we have an adapted pipe coming out the side. So much easier for us when we rarely use campsites.

 

[L' Hobo]

Might it be better to run a concrete shallow half pipe (like an inverted speed hump) across the complete roadway to a drain at the side which is most convenient to your underground pipework?
This would cover all M/H drains and, possibly, slow traffic or cover with grate?

 

[emjaiuk]

The drainage channel is easy

High quality channel drainage systems available in black HDPE gratings or galvanised steel gratings available at Plastics Express.

It’s getting the groundwork slopes right to prevent sink waste pooling over the adjacent ground.

I thought this thread was about the grey water drain tap/pipe on the motorhome?

Where did ground drains come from? (Although they are interesting of course)

But threads often go off on a complete journey of their own on here - that's what makes it FUN!

My post was a request for information to help us design a practical grey water disposal point, be it to one side but still in the road, drive over or off the road but using a length if pipe to connect to the drain tap point on the vehicle.

 

[VandM]

This looks to be the most practical as it'll allow drainage from either side of a vehicle.

You might need 2 put together (double width) as 'some' of us men are not very good at aiming their water?

EDIT: Plus, seriously, remember, some M/H owners cannot be bothered to turn their taps off after draining their tanks. (there is always some left in) which is trailed down the driveway!

That's why you need the concrete to slope towards the drain, or stay on your knees while your water is running

 

[VandM]

Agreed, a slight benching in towards the drain along it's entire length will be the way to go.

exactly what I would suggest. Lay channel drain down the centre and put a run off in the tarmac/concrete from each side to the channel. This way you catch water from all possible outlets. Put a short hose and tap beside the drain off to rinse down any foul water

Many sites have this and a dedicated fresh water standpipe on the same bay

Yes. Because our tap exit is under the van it is quite difficult to know whether you are over a drain until you open it. We cant see the exit point by bending down.
