Eternabond is expensive but it's a really good product. I have about 45 ft that I'm not using. I'll be happy to send you a snippet big enough to cover the crack in the tank. Send me a private message if you're interested. Good luck!

water tank repairs

There are a number of products that can be used that sometimes have success in repairing a cracked water tank.

Depending onh the cracks, and the material used, a fix could be short lived or even last a long time.

The big concern, is to "NOT" used any material that could contaminated the water.

You might try this stuff. TAP Poly-Weld Adhesive: TAP Plastics& It say it bonds to poly tanks after they have been flame treated and may be worth a try. Let us know if you have any luck !!!

An old repaired crack in the bottom of my water tank came loose on a recent camping trip and soaked my floor. I tried some JB Weld for plastic but it did not hold. I think any repair will be temporary unless you plastic weld it and then that even may not work. I decided to replace my tank and use the old one to replenish my water supply with when we are boondocking. I carry it empty in the back of my truck and then fill it when I need to replace the water in the trailer. I elevate the tank a little and just gravity feed the water into my trailer tank. I bought my tank for $70 from RV Surplus. However as we all know, new solutions have new problems. The fill connection is smaller than stock and not in the same location and the same angle so I had to jury rig some plumbing fittings to get it to work. It now takes much longer to fill using gravity feed. If I had it to do over again, I might pay more and get the stock tank from Andy.

Allow me to chime on with a little real world experience from the 'field'. While EternaBond is great stuff, it will NOT seal a polyethylene tank permanently....and by that I mean that it will NEVER leak at the repair point again. Been there....done that!

There only 2 absolutely fool-proof methods that WILL work to your 'eternal' satisfaction.

1. REPLACE THE TANK WITH A NEW ONE

2. Find someone who is accomplished at plastic welding and has experience working on poly tanks. They can use the hot air method (BEST)or the direct heat contact method (still good). If done properly with the correct welding rod (same material as the tank) it will last forever. Not saying that the tank won't split somewhere else though, which is what makes Andy's solution #1!!!!

Sometimes, the savings made by not replacing a problem, can result in spending lots of money fixing new problem/problems caused by the original issue.

Ruined batteries, rotted wood, damaged drapes, fatigue cracks in the frame and shell, are just a few of the unpleasant results.

In short, get a new tank. It is cheaper in the long run. When you think of the cost over a 10 year period, it ain't so bad.

The best fix is melt the plastic back together, being very careful.

Harbor Freight has an inexpensive plastic welding tool.

Epoxy's won't hold.

Hot glue's will usually fail.

I used the plastic welding kit from Harbor Freight and got good results fixing my black water tank. This is the way to go.

I ended up using the heat/weld method. Using an old soldering iron and milk bottles as welding rod, I made the repair. The big problem was that as the tank heated up, it wanted to drip inward to toward the inside of the tank. It took some time to do, but it seemed to hold.... for now. Not having a high level of confidence in the repair, I then constructed a drip pan out of left over roof flashing. The thought being that should it leak, the drip pan would contain the leak and prevent items from getting wet. Which is my main worry as the floor and everything else is made of Aluminum.

If you decide to weld it back together just be sure to drill a 1/16 hole at either end of the crack before welding or you will find the crack will continue even after you weld it. I welded mine with a hot iron and some polyethylene pellets and its holding great. (knock on plastic!)

I have a 77 Argosy that had the same leak, I also used J-B Weld to repair the tank with only a wet rag wipe down. It has lasted for 5 years ...so far.

J-B Weld Repair

The key to the J-B Weld repair is oxidation of the polyethylene surface. Epoxy will not stick to new polyethylene. The surface must be oxidized either by age or flame to achieve a bond.
