grey water tank

Hello Lovegreen,

Congratulations on picking up your van. I have not stored my van for long so I'm not sure of the best solution. A suggestion would be to empty it as much as possible then flush it out with fresh water until water runs clear and then leave it. On our tank there is a cap to inset a hose to enable the tank to be flushed. Hope this is of some help.

Hi lovegreen,

Sodium metabisulphite (SM) is a very good answer to cleaning your grey water tank. Empty the tank, mix up 2 to 3 teaspoonsfull of SM, a white powder, in water and put it down the sink into your tank and take the van around the block to slosh it around. SM is used as a antioxidant, disinfectant and in foods as a preservative - marvellous stuff. It is what you want to chemically clean your bottles when home brewing. I use it to "bed down" my water tanks when the van is being parked up. To get my mix into the three water tanks I mix the SM with a litre of water, pour it down a hose and then connect to the water inlet manifold, select the tank you want it to go to and give the hose a squirt.

MS used to be available in Wollies supermarkets (comes in a small plastic orange screw cap container) but I notice lately it is more difficult to find. Failing Wollies it is available at any home brewing shop. A small container will last you ages. Watch it when you open the container, don't sniff it. It is a fine white powder floats in the air and will catch you in the nose and throat. Great stuff, have used it for years.

I found that a bit of pool chlorine, 1:4 strength, about 10 litres of mixture, sloshed around by driving the van and then drained, keeps the smells away. After our first trip with the tank, I didn't do this and the smell in the shower booth, when we opened it for our next trip, was very noticeable. No smells after chlorine treatment.


Kind regards



Geoff
