Whenever people complain about others dumping grey water, the word smelly seems to come up. We dump ours on the grass at home and it's never been smelly, never left any residue, no clouds of flies have been seen and it has not killed the grass. I feel that we must be doing something wrong?

The problem is 2 fold: firstly you don't know what others put down their plug holes so whilst you're may be fairly 'clean' due to minimal cooking oil, grease, or other contaminants others may not be quite so careful, secondly you don't know how often it has been done and with the best will in the world a place that has had the waste dumped on it daily can easily get smelly never mind soggy.
 
Stored grey waste starts to smell pdq. But emptied out quickly / frequently is less so. If that’s not too simplistic...

If emptied too quickly after mrskevenh’s shower it’s still warm & bubbly 😳
 
We’ve had a nice bubbly dump on occasions giving the drain a good clean and freshen up.
I do like to hose it down afterwards if there is one to use.

And now I must eat humble pie. My wife emptied the grey tank yesterday and said that the water was smelly. I suspect this is down to the recent high temperatures. I have just rinsed the tank out at home with a nice industrial cleaner and I hope that our water smells of roses next time.

RV's have large holding tanks so it might sit there a while. When emptying the grey is often more objectionable than the black.

In addition to Minxy Girl's valid point, it's also the rotting / decomposing remnants of any food waste ( bacteria ) that end up in the grey waste tank that causes the smell.
 
I must admit, that whilst watching videos to prepare for our rental trip, I was prepared for a bit of a pong when emptying the cassette. When actually doing it I really didn't have any problem with that at all (although we might have been a bit heavy-handed with the blue to be honest!!) but my goodness emptying the grey, especially when using a small container to drain off a bit, was a lot more unpleasant in the olfactory sense than I was expecting!

My grey water has the same aroma as Channel No 5...

As opposed to Chanel No 5? Is Channel 5 one of the overflows from the local sewage works by any chance? :giggler:

our grey waste was quite smelly when we first had the van and what came out was quite thick consistency I think previous owners had forgot to drain after there last trip,(they had forgot to drain fresh over winter)but now its been well flushed and we strain washing up water what come out is virtually clear and does not smell, probably helps that I try to dump it daily
 
Nothing that a couple of squirts of bleach doesn't cure.(y)

Leaving 15-20 litres of fresh water in the grey tank to swash around on the journey home helps clean the tank .... but empty it as soon as you get home before it settles.

I'm in the process of buying a 19 year old van. I knew my budget for the van, but the budget for tank cleaning products seems to be adding up to a suprisingly large amount!!!
 
Slightly off topic%?

How many of you put washing in your machine when you return home from a trip away. Without putting on a rinse first, empty.

We put on a rinse before we leave with a drop of bleach. Then when we return, quick empty rinse first.

The water that sits in your washing machine goes stagnant and stinks. If you don’t rinse first, you are washing your clothes in it.

I think you should have read the first few words of your post first, "Bubbly dumps "are not very nice in my opinion

Exactly, the worst offender for bad smells in the grey system is SOAP and detergents breaking down into a stinky grey slurry. Food waste can sometimes cause smells, but normally it is down to soaps

We dump ours on our own drive when we get home and never it seems to smell or leave grease.Usually dump when away at a service point when full 3-4 days worth.
I leave it open over winter and between trips so no accumulated crud.
Depends a lot on how warm the weather is and what you tip down the sink.
