Cleaning Water Tank in Caravan

Hi Deanna

I use Miltons tablets, baby bottle cleaner.

Normally use about half strength of the directions on the packet, leave in for a few days and then flush out the tank.

If you want to try Bicarb, about 500grams dissolved in a bucket of water, syphon or tip it into tank, fill tank to top, leave for a day or two, drain and flush well.

Tastes can be caused by using ordinary garden hose to fill tank, always use food grade hose to fill tank.

Tankcleen form Caravan outlets does the job About $10- $15 a tin made for the job

If you had filled the tank from an unreliable water source then 1ml of bleach to every 10 liters of water will make it potable and that dose does not appear to affect the smell or taste.
I used that ratio on my boat on a 3 months Kimberley cruise where the tanks were frequently topped up from waterfalls.
So, after you had cleaned your tanks - you could also use a stronger dose of bleach for this, which must be flushed out completely - an occasional dose as above will prevent any further problems.
BTW, my water tanks are the rigid black poly caravan type.

Good place for info on cleaning water and water tanks is the B.E.S.T. Water Filters web site. They have a pdf file re 'The method we recommend to clean tanks with 'questionable' quality or bacterial content. Safe and non-offensive solution!"

I second using bleach to clean a tainted tank.

I don't believe the problem would be from filling with anything but "Food Grade" hose though.

I always fill my tanks at home with the garden hose as my Blue hose is not long enough and have never had a problem.

Saying that, I always, where possible use the blue hose when propped in a park and have the van connected to a tap via the hose.

I don't doubt the water could pick up a 'taste' when left sitting, under pressure in the hose perhaps in the sun too.
