Waste Management

Don't store the waste for long periods is the first thing even then smells can build up. I either use a "Tank Cleaner" sold in the dealers or wash detergent down the sink with hot wather and let it slosh around for a while before draining off. Seems to work.

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.

Thanks to all. New waste management policy to be adopted - empty more frequently! I have the Thetford and will use it before we set off tomorrow.

I would heat the water and pour the cleaner down sinks then follow through with the hot water so the pipes get flushed as well.  Would then  half fill the waste tank with said hot water so it has a good cahnce to slop around on route and hopefully it would be OK. 

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's too common a practice, unfortunately, Auchtavanner. I've even heard of it happening on CC sites. Despicable.

Not all MHs have the waste drain in the same place. Ours is nearside and our fresh water tank can be drained on the offside. You need to see the colour of the drain valve to be sure which it is. Fresh water fittings are blue, waste water valves are grey/black.

Another tip is to leave the plugs in, stops any smells emerging. Also avoid any cooking water from greens, certain things really pong in the tank. We've just bought some Milton type steriliser from Lidl, but I wouldn't put anything too harsh in the tank. I've used Zoflora this summer, various pleasant smells on offer. Warmer weather affects the tank so emptying it often as possible is the best solution, as already suggested. 

Throw in a biological washing tab and it smells reasonable no matter how long you leave it. We have a 160L toilet tank. Never allowed it passed half full but two biological washing tabs makes it smell okay when emptying. 

Auchtavanner, more likely to be fresh water pouring out of the middle of a motorhome.

Even if fresh water, is this legal or acceptable practice?

Just wondering as it would be a lot easier
