What do you use to repair poly tanks? The one on my sprayer(300 gal.) has a small crack in it. A new tank will cost me $210, but I'm already over my spending limit on this project, so the new tank isn't an option.
Thanks,
Greg

Repairs are made at the manufacturer by "welding" the hole with a rod made of the same material. If you have a soldering iron and a scrap piece of the material, you might be able to make a "weld" yourself. Be sure if there is a crack that you drill a hole at the ends of the crack to stop it from running further.

Easy fix. Either borrow a plastic welding kit or have someone weld it for you. This issue has been covered on several other boards. A plastic welding kit will cost around $30 at Harbor Freight. You need to add a voltage control, also at Harbor Freight to make it a very useful tool. The voltage control allows you to lower the temperature, and thereby keeps you from burning the plastic. I believe the voltage control was priced around $15. Last year a machine/tool magazine had an excellant article on what to buy and how to do the repair. I went ahead and bought the recommended welding kit, copied the article, and currently remain on standby waiting for a poly tank to crack. Although I will strongly consider practicing a bit before starting on the Real McCoy.

Been there, done that; doubt that either Jerry or old have ever "fixed" a spray tank as you described (would work in a stationary/non-moving tank). Tried the fiberglass/bondo/J B Weld and whatever else I could find. Had a crack in the "bend" of a tank on a Spray Coupe; problem was that it would flex-in-use. All of the above would work for a few days/weeks, but would eventually fail. Finally cut some metal straps and bolted them across the split, inside and outside tank; first laying down a layer of J B Weld and after they were in place, covering the whole patch with another layer. It was a *itch getting to the inside to get the bolts in place, but it was a permanent repair.

Yeah, you're right. The crack is probably there because it is flexing so anything halfway rigid (like JB Weld)would just crack out again. Stop drilling the crack, however will keep it from growing.

Hey Jerry, didn't mean to flame you or old; just didn't think what y'all were purposing would work..... ....under the circumstances.

No offense taken, thurlow. My suggestion was just that. And you were right, I haven't had to do one yet.

Stop drill the ends of the crack and then use some JB Weld on the inside if you can get to it.

Fiberglass repair kit from an auto parts store should fix it up nicely

Neither JB weld nor Bondo will stick to polyethylene.

Welding gets difficult when the crack is coated with some herbicides, and the fumes might be hard on the welder.

Clean the crack with solvent and trim edges as necessary. If you are worried about fumes, use your chemical applicator respirator which you should have anyway. I don't believe fiberglass nor bondo would stick very well to a contaminated surface either.
