I've got a water tank under my CT and it gets a bad 'iodine' type taste in the water. You can even taste it in coffee and tea made from it. I've flushed it with chlorine and also tried vinegar, but it comes back. Any ideas please?

Have you tried searching the archives, I seem to remember a few with this problem with lots of solutions. One I vividly remember is not to fill your tank from a hose unless you let the hose run for a bit, apparently water already in the hose bakes in the sun etc and isn't conducive to great water in a tank.

On the Forum of Ultimate Camper owners, there has been some discussion about this matter too.

The method that seems to work is to half fill the tank with water and add a liberal dose of BiCarb soda.......take the camper for a drive to slosh the mixture all about and then empty it out.

Hope this will assist.

Try Bias Boating Marine or Whitworths Nautical World for tank flushing/taste remover products or alternativly give your tank a heavy dose of bicarbonate of soda, allow to sit for 24Hrs then flush.

I believe from may previous posts that the type of hose you use to fill the tank can have an effect. I use my garden hose that lays around on the front/back lawn and have no problems to date.

Best of luck

As roachie has stated, it is better to slosh the stuff around....bicarb is a cleaner/scourer and not a disinfectant, therefore it will do more if agitated. It's fine particles actually loosen any contaminants off the container and this should be flushed out then. The other thing to do is just before you drain the tank, take it for a quick drive etc to stir the water. This will make sure you get all the crap out that has settled on the bottom of your tank.

BTW twinkles, what type of material is the tank made from, plastic, fiberglass or SS. Some members may have a better way to remove the taste from different containers.

The old wifes tale is to give the tank a liberal squirt of lemon concentrate ....we did that with ours and never have had a bad flavour.

I had a similar problem with mine (black plastic water tank) as well as "floaties" in the water. I had always drained it as much as I could after a trip, even jacking up one side to help it drain. Anyway I ended up taking the tank out, cutting a hole in the top, so I could actualy get my hand inside and give it a good scrub. I made a cover from stainless steel glued some rubber strip to it and screwed it back into place with some stainless anchor clips for the stainless screws. So now I know its clean.

Hey Twinkles,
I havea 95ltr stainless steel tank mounted under floor of my GQ, I recently had the water go "off" so i drained it, half filled it with water and 2 packs of bi carb..took it to Menai for a few hours of sloshing around (and a fun muddy day ) and came home. Sat the car over night, then went back down for 30 minutes of rough stuff. Drained it at Menai when i finished having fun. Came home re filled it..drained it again..refilled it and now its fresh again.

I found out its caused by the filling hose i use, clear plastic and sits in sun when not used...not a good thing to do. So now I havea proper black hose that stoppes any sunlight getting in.

I had the same problem with my Jayco Finch. Went to a Caravan supplies place. They had a number of products. Some which required completely flushing and removing the tank and such. I found something called CAMCO/RV Taste Pure. You add this as directed to the tank and it eliminates the taste. Cost $20. You use 1oz per 20 gallons of water. Will last for ages. 16oz container. Easy as.

I used half a bottle of vanilla essence and half filled the black poly tank with water. Was cheap and effective.
