Waste Management

How about a Bio Tab, they work for the toilet cassette so should be OK for hte waste. 

Cheap bottles of coca cola  work apparently or thetford do a bottle of waste tank cleaner which is good.

agreed, both Michael's recommendations are oft given advice, and reports of success are common....

only last time out, i dropped a bio tab into the waste tank for a stir around on the way home...as said, thier continued use will keep a cassettee pristine, seems the same for a waste tank.

the cola trick (the cheaper, the better) is also a winner it seems....

I was passing a motorhome on the way home at the weekend and noiticed that a lot of water was pouring out of it from around the middle of the van on the driver side. Could this have been someone dumping grey waste whilst driving?

Is this a practice commonly used? Personally i thought of empty and rinse prior to leaving the site.

It is more likely residual waste or clean water. It is almost impossible to empty tanks fully while stationary and if having emptied at the service point you don't the close the taps it is almost inevitable that more will be dumped on the road as you bounce along.

When leaving a site, I fill the sink with the remaining hot water, dissolve a bio pod in it and close the waste drain tap before emptying sink. Empty tank at home, it seems to keep the tank sweet..... 

Tried a laundry tablet. Brilliant! Much better than the Thetford tank cleaner at about £7 a bottle.

Make sure the laundry tablet is biological. We buy the dissolvable ones from Aldi. They are cheap as chips and work very well. When I empty the toilet holding tank, I flush it out and add two capsules and a little clean water. Same with the grey waste tank, pop in a couple and both tanks smell reasonable when being emptied and we never get ant smells into the van.
