Emptying Grey Waste (1 Viewer)

[Paul Wilkins]

Am I the only one here that gets very very very bored at the speed that the grey waste tank empties? Has anyone done a 'pumped' conversion on theirs?

It’s best to run a pipe from the drain to the edge of your pitch and leave it open

 

[Larrynwin]

Might well need some drain clear or similar through the system could be gunged up.

You need to multitask.

While it's draining, empty the toilet cassette, fill the fresh water, wash the bugs off your windscreen.

Yeah... even that is very very boring to watch

It’s entirely possible that you may need to get out more

That is entirely helpful.. thanks.

Gravity should do the job, has it always been a problem .

Its so slow. It can take 10 minutes to empty the tank as the bore is so small. Plus of course the drain cock is so near to the ground that it can get ripped off the van going over speed hump etc. Not exactly an elegant solution from Bailey

I use a low level wheeled tank and run pipe in to it and leave valve open when pitched so when ready to leave tank will be empty , just wheel tote tank to tip out.

Seems a little overkill to carry a WasteMaster when you already have an onboard waste tank, but I take your point, it would certainly avoid holding up a queue of other MHs all waiting at the service point to dump their tanks.

Bet no one visits you. It stinks.

I have a low level tank on wheels but not as low as the drain pipe. When I tip the tank over 45 degrees to remove it from under the drain half of the stuff spills out. Means it’s not so heavy to tug to the service area

When I had a caravan and a Disco 4 tow car, I did once loop the WasteMaster handle over the tow hitch and tug it to the dump point.. now that's lazy

Might need a colonoscopy (spelling ) I would try a drain cleaner before going mechanical

Perhaps I'll shove a brush up it.. but its been rubbish since new.

Paul....How big is the bore of the waste pipe? I thought the Bailey was easily 50 mm?

[PhilMary]

A larger bore pipe and valve may be the solution. Screwfix is your friend.

Ours just has a big hole underneath and a valve it gushes out pretty fast when you pull it.

Its the same diameter as convoluted pipe (28.5mm)

 

[Lenny HB]

You could fit a 40mm Ultradrain the same as they fit on a lot of German vans, it shouldn't make it any lower if the bottom of the outlet is fitted at the same height as the present one.

Thats surprised me? Thought it was bigger than that? Our neighbour has the same vehicle and he has a 50 mm outlet. What I dont know is if he has altered his because of the same reason you now have?
30mm is a small bore realistically. It may be the issue you have rather than waste and build up of slurry etc.
Pump out is a possibility but a new pipe and tank cutter may be the cheapest way and most effective for you. Go 50mm and remove the old one and fit a new one. The glue that they use for PVC pipes and fittings would be best instead of sealed pipes . Cut out and refit a glue a new pipe and elbow in place . Job done!

We used to have the slow draining grey waste and our was down to the woefully small bore of the grey waste tap.
This is from the post of what I did to rectify the problem.

-----------------------------------------------------------------------------------------------------

I'm looking forward to my next dump ........................................................... grey water that is.

Dumping our grey water has been a source of embarrassment on more then one occasion with other motorhomes queuing up, drumming their fingers waiting for the paltry flow from our grey waste to finish.
Spurred on by seeing what Tinker2 had done to speed up the exiting of his grey water, I have today removed forever the shame and embarrassment of slow flow.

I purchased from CAK Tanks a 28mm grey waste drain tap and a 28mm to 25mm pipe reducer.

The tap - https://leisurelines.net/28mm-grey-waste-water-drain-tap-valve-4303-p.asp and the reducer - https://leisurelines.net/28mm-grey-waste-push-fit-male-pipe---25mm-hose-adaptor-j-433-p.asp

A simple job on our Elddis Autoquest 175. Remover the offending original grey waste drain tap, remover the rubber grommet on the tap mounting bracket.
The new tap is a nice tight fit into the mounting bracket and I used a jubilee clip to secure it in place, reconnect the hose from the grey tank and job done.
I can now soak ever bodies shoes at 20 paces.

The old tap = 18mm inlet and 14mm outlet

New tap = 23mm inlet and 28mm outlet


Inlets

Outlets

I nibbles a bit out of the mounting bracket to help lock the tap outlet to the bracket.

Mine was ridiculously slow once, (even more than normal). It transpired that there was straw up it where a little mouse from the storage farm was thinking about making a nest.

You don't want to get straw up it, it's very scratchy is straw, Very scratchy.

Some members of this forum empty their grey waste at 30 mph or faster !!!!

Buy a better motorhome!!

Our 100litre waste tank has a 40mm diameter outlet and empties in a minute or so at most. Mind you, you have to stand well to one side to make sure you don't get soaked.

40mm pipe and a full bore valve. It’s empty by the time I’ve emptied the cassette, or before I’ve filled with water.

 

[Larrynwin]

I carry a Fiamma wheeled waste tank as not often possible to get mhome to dump point.

 

[pappajohn]

Mine used to take a while to empty.
But it was a 60 GALLON grey tank with a 3" outlet.
