A-122 water tank repair

Have a short hair-line crack/leak on lower sidewall of fresh water tank on a 2012 A-122. Need to determine what TYPE of plastic the tank is made out of, so that I can figure out a repair scheme.

Typical plastic tank/radiator repair kits will not bond to either polyethylene or polypropylene plastics; hoping the tank is made out of another type of plastic.

Any other ideas on tank repair other than plastic welding??

Thanks,

Tom

Might be worth a try with 3M Extreme tape or eternabond.

Just thinking how about a bead of hot glue to a cleaned surface?

First I would contact FR about a warranty repair, if you are the original owner. Secondarily, they might be able to give you definitive information on the plastic.

FR popup group 574-642-2640

I think you are on the right track in looking for the proper plastic welding method. If that doesn't work out then Big Vic's idea of taping sounds good to me. Drill a small hole at each end of the crack to inhibit spreading and perhaps fill with food grade silicone caulking.

Anyone try JB Weld for plastic? It is a two-part epoxy product. It may not be flexible enough and I would wonder about toxicity with log term contact with potable water. It is a very durable product though.

I used some fiberglass matt with fiberglass bondo on a MH I had a few years back. Never leaked again
