Hello folks, it's been quite a while since I last posted, but I always read others posts. My partner and I have just purchased a 2011 Coromal Lifestyle 667 and it doesn't have a grey water tank fitted. We enquired at the company where we purchased it from if they could fit one for us prior to pick up. We were advised that there was room, but that the water from the shower would be too low and therefore couldn't flow up to the grey water tank. At least I think that was the crux of the problem. I wondered if others have been in a similar situation and if there's a way around it. My partner thought perhaps a 12 pump to get the water from the shower into the tank. Otherwise I guess it will have to be a portable grey water tank. Looking forward to your answers.....

From our experience only, I found all dump points almost higher then the caravan outlets making it hard to discharge.
In the coming days after some serious thoughts on this matter we are going out to buy a portable greywater tank with wheels for less then $100 making it a cheaper option.
The main advantage is we can disconnect form the caravan and take only the tank to appropriate point for discharge. We use about 25 litres a day of water when we are being careful.
I would of liked the tank under caravan for no fuss storage and another fixed item.
Re (The main advantage is we can disconnect form the caravan and take only the tank to appropriate point for discharge. We use about 25 litres a day of water when we are being careful.)
Also have a Tote Tank. A number of times have parked 100m from a Dump point, no problems with a tote, no need to move the van.
My solution to fitting a grey water tank is as follows.
I had room behind my van discharge point, so I fitted a 110 ltr. tank about 300 mm to the rear of the outlet for the sink/shower drain pipe.
If I need to be fully self contained I simply connect the attached unit in the photo.
I have a large tap on the outlet of the grey water tank which I can connect to my waste water hoses (All swimming pool suction hoses) and discharge into a "Dump Point" or water a tree. Its only grey water. However for the sake of some back lash I always use a dump point.
The unit in the photos is from the "Big Green Shed". Will not be difficult to replicate.
SHOWER TO HIGHER TANK - make a small box either metal or wood and have a 12V pump and float valve to pump shower water into holding tank.. permanently fitted
If wood --- size to be small enough to house the valve and pump and say 5l of water, seal with fibreglass and have sealed screwed down lid. Easy to do and you just shower and pump is automatic. The trick is to match the output flow from shower to the pump capacity otherwise pump just shuts off/on off/on. Our shower output is 6l per minute typically but you can measure yours easily. The 5l in the pump box helps to keep pump running rather than stop/start.
HOLDING TANK TO WASTE
Easy to match another portable pump ie wire to cigarette lighter plug or similar and fully sealed pump with say 4 m of hose to waste.
If you think this through it's easy. Maybe go to a marine supplier and look what the have for boats and see what you can do.
Marine gear is expensive (tax) so maybe look first and see what you want and source online (get model numbers etc)
Hope this helps.
PM me if I can explain more and I'll give you my phone number.
Cheers Baz

Portable Grey water totes are mostly acceptable as self contained, I seen RVers take them into bush and empty them.......defeating the purpose I suppose.

A grey water tank will do very little to your loading weight. The hardware you add, what will it weigh? I suggest around 10 kg or less. That is all you will lose from your load allowance. When on the road you will not be adding weigh to the van unless you refill your water tanks without emptying water from the grey water tank. All you will be doing will be shifting your water load from one tank to another.

There are some who are borderline exceeding weight limits. If the OP is close, he needs to take it into account. If he has ample to spare, then all good.
Whilst it may be minimal, if you are right on the edge then it is relevant.

Gday...
Peter is quite right ... unless the grey water tank is full and the fresh water is refilled BEFORE emptying the grey water tank then there will be an impact on the weight of the van. Otherwise, the transfer of water from the fresh to the grey simply moves the existing weight without increasing the overall weight.
If the empty grey water tank and fittings are about 10Kg as suggested, then that is just like when you head off with an empty toilet cassette, and then it is full a couple of days later ... it holds about 18>20Ltrs of water/waste ... so that in itself will add 18>20Kg to the weight one left home with.
If one is THAT close to being overweight, one needs to VERY carefully check just what one is carrying.
Jest sayin'
Cheers - John

I do not understand why the shower water would be too low. In all vans I have looked at ( including ours ) the outlet pipe from the shower drops vertically from the floor outlet and then has an elbow assembly to go under the chassis rail and back up to under the floor. Then another elbow and with a good install there will be a hepvo valve, then the pipe runs at an angle downward across the van to the outlet at edge of van.
This gives the option of cutting the pipe going across the van and connecting to a grey water tank. All other water gets inlets as well and then one outlet from the tank to waste outlet.
All this assumes there is room for the tank at a place for this to take place.
A photo of your shower outlet would be good if not as I have described.
Firstup, Congrat. Happy Daze on buying a Coroma, like we have done .
I have installed a grey water portable tank, and I have not had to use same as yet. Plus I have not been challenged or asked if we have waste water disposal unit. Of course the tank is in sight and easily seen.
Now some folks may say I am a naught boy for watering the trees and grass well away from any waterways. But if they ( the trees and grass) could talk they would thank me and many others for their survival.
However I do recognise that "Times they are a changing.""
So I guess that one day I will have to also change.
We have a Coromal 667 ( it is the off road model so a bit higher) and I have fitted a grey water tank, I did the job myself and it is working well. The shower runs into the tank with no issues. I bought a Rotamoulded 100 litre tank which I strapped to the chassis with metal straps. I have three inlets to the tank, wash basin / washing machine, shower and kitchen sink plus a breather/overflow and outlet. The outlet is just behind the right hand rear wheel and has a ball valve on it. I have found out by experience not to use the washing machine as it will overflow the tank.
I did the right thing and had a grey water tank installed in our new retreat van.
Understand the logic but have to say as a Newbie it amazed me how many caravan parks dont have a drain and encourage you to run the Greg water on the grass or trees.
We have only been on the road 10 months and covered 30,000 Kims and I understand one day it will be a must have but right now it was an expense we didnt need .
Sorry the boss corrected me we did use it once in a national park in WA as requested by the park manager.
I always put a stocking over the outlet to catch food scraps and grease .
also stops us worrying about a frog getting in the system.
Understand times are changing but do you really need it now ?
I for one am not so sure.

Yes,, try the western side of lake MaQuarrie ,, stayed in cheap site not 100% free along Murray R needed on and external bucket NOT acceptable. Other places ahd to have em Theresa Dam QLD again no buckets - saw people kicked out in about 2014

Hi - we have a Coromal Lifestyle 667 also and Joe installed a 6 inch stormwater pipe, capped at both ends with all three drainage outlets running into it and at the rear on the drivers side installed a drain tap. Tap could be open if no problem putting grey water on ground but if required could be closed off. Pipe is situated at the rear of the caravan and about 1/2 m forward of the rear bumper bar because of ground clearance. Let us know if more info required.
G'day Happy Daze, i installed a grey water tank myself,not an overly complicated project.
However,to get over the height problem,i had a mechanic change the springs to on top of the axles, which lifted the van about 100mm.
This obviously gives the van more ground clearance as well, dosn't unduly effect the towing, and the grey water tank works well.
Depending on your plumbing set up, i installed a 40mm diversion ball ****, so the water either goes into the tank or out the waste pipe as normal, when going into the tank, use a screw cap on the usual outlet, good luck.
