Removal of fresh water tank T2670 Done!

Finally removed the freshwater holding tank today! The job required the removal of the stove, stove vent hood, kitchen cabinet drawers and draw sliders. The tank is 11"W X 12"H X 52-1/4"L.

That is the good news! The bad news is that everything I read about repairing the tank says no epoxies, sealants or glue will stick to polyethelyne plastic?

The leak is at a drain connection with a plug in it. There is really no reason for the fitting on that end of the tank anyway! It looks like perhaps the plug was tightened too much during installation and now has fractured and leaks.

Any suggestions? Looked online and can't find tank with similar dimensions. The current tank is 32 gal and the measurements are pretty tight.

This claims to bond polyethylene, is resistant to water and freezing temperatures.

Thanks guys, I think I need some sort of filler adhesive because of the cracked fitting that has to be filled. I read the fact sheet on the Loctite and it is not recommended for this.
I have to see if someone locally does plastic welding. A new tank ,probably smaller is about $200.00 plus shipping (ouch)!

Thanks Kitty, I actually looked at this site. The kit is $145.00 plus shipping(which they would not disclose unless I gave them my credit card number etc.). I am still researching along the welding idea. But I am not sure about using the kit, at that price I might have to get another tank. Seems a lot of RV and boat owners have the same problem.
Now that my kitchen area is torn apart, I am anxious to put it back together soon!

Kitty,
I found additional info on the welding kit, and as a permanent repair it does not look promising!









Our popular, do-it-yourself kit is good for all plastic tank repairs such as water tanks, spray tanks, fuel tanks, ATV and snowmobile hoods, etc*. In fact, it is appropriate for any polyethylene plastic repair. Kit include has 35 or 40 watt plastic welder, a wire brush, and a welder holder. Also included is 30 feet of FUSION GRADE PE Welding Wire (stronger than the original part). Perfect for the D-I-Y. (*Please note that polyethylene can only be welded for structural integrity. It can not be glue properly. All adhesives, glues, epoxies, etc., will eventually fail or breakdown on a polyethylene repair.)
