tinstartrvlr Posted February 15, 2016 Report Share Posted February 15, 2016 Greetings everyone... Normally I am here to ask a question since I have found no better place to get an answer or a direction when I have a problem. Today however I thought I would share something that I discovered, in case someone can else can use the information. Also, feel free to laugh. Today I tried to make a minor repair using a screw in the vicinity of my holding tanks. As my luck would have it, I managed to screw into the gray tank. My first thought (after the one about how stupid I was) was that now I no longer have a minor repair, but a major repair. Or, could the leak be fixed? Replacing the tank was a scary thought, and I knew caulk wouldn't cut it, so...... Empty the tank, and off to the neighborhood home repair store (you know, one of the BIG ones!) There I discovered something called JB "Water Weld". It's an epoxy that, according to the store associate, is made for wet situations and even works underwater. It's a putty that you knead between you fingers and then apply. Skeptical, I bought a tube (about 6 bucks) and went to take on the repair. A little sanding around the hole, knead the "dough", and press into place. I cannot believe that it lived up to the hype. It was fully cured in one hour (as it says on the package, but I am in the desert at the moment) and after taking a long shower, I checked to find that it did in fact stop the leak completely, and the plug didn't want to come off even with me picking at it! Amazing! Leave it to JB! It is supposed to withstand 900 psi, far more than my 29 gal tank will probably ever create at that little hole. We shall see, but I feel confident...... Hope this helps. Ya just can't RV without a hitch.....! Link to comment Share on other sites More sharing options...
Ranger Smith Posted February 15, 2016 Report Share Posted February 15, 2016 If that does not work you can just put a piece of eternabond tape over it. Steve and Joy Amateur Radio Operator WZ1T . . .

tinstartrvlr Posted February 15, 2016 Author Report Share Posted February 15, 2016 Good thought Ranger; that didn't occur to me and I have some on hand! Although the putty was awful easy to deal with..... maybe a piece of Eternabond over the putty just for good measure! Ya just can't RV without a hitch.....!

Ed ke6bnl Posted February 15, 2016 Report Share Posted February 15, 2016 I was referring to the color of the tank because the Black color tank is far easier to repair then the opaque clear white type. 2000 National RV Sea Breeze 5th wheel 30ft.

bigjim Posted February 15, 2016 Report Share Posted February 15, 2016 I had some good luck with some cheap brand of epoxy like this on one of the white/opaque ones. I repaired a black tank at a critical joint where the piping starts just before it made the turn toward the dump valve. The hardest part was getting it dried out even on the inside of the tank to where there were not ANY drips. I used an epoxy called MarineTex. A couple of years ago I had some major damage due to running over a "road alligator" and learned about plastic welding tanks. I had not done it so I ended up getting someone who did it "proffessionally" for $80. It could have been more depending on the repair but that was actually $20. under his base price to come out and do it on site. He cut me a break to $75. because he appreciated that I was volunteering with the Forest Service but all I had was $20's and he didn't have change and I was real happy even if it had been more. I like the idea of the eternabond over the repair in you case but I would not make it much bigger in case you ever had to get it off and do something different. One of my big worries in both cases was not to do something that would mess it up so it couldn't be repaired. Link to comment Share on other sites More sharing options...
lenp Posted February 15, 2016 Report Share Posted February 15, 2016 Another VERY easy repair is to use a "well-nut". Just drill a hole the correct size and insert one of these: https://www.grainger.com/product/POP-Well-Nut-3ZLV6 Many of the sensors for tank levels use these for the electrodes. Available at any hardware store. Lenp USN Retired 2002 Winnebago Ultimate Freedom 2012 F150 4x4 2018 Lincoln MKX 2019 HD Ultra Limited Link to comment Share on other sites More sharing options...
