Sprayer tank

[MSJ from MN]

We have a crack in the plastic water tank on our sprayer. Anyone have any ideas on repairing it?

There are people in this area who do 'plastic welding' on ag tanks. Never had anything repaired, but supposedly it works. There are probably plastic repair people in your area, too.

U can use a fiberglass repair kit, sold at most auto parts stores. Works well and lasts.

They make what's known as a "poly welder". It's basicly a large "glue gun" that utilizes a type of welding rod that melts the plastic and seals the cracks. It doesn't work too good if the crack is in the seam of the tank. It might be good for a short term fix. Plastic usually doesn't crack unless it is old. 'May just have to bite the bullet.

Do you think two part epoxy would work?

We used it at work to repair plastic door panels. It seemed to work good.

Repaired our water tank with fiberglass repair kit.

Be genereous with the resin application.

BTDT.......plastic 'welder' might work; I've got my doubts about the other repairs mentioned. UV rays are tough unless it's a plastic designed to handle the sunlight. Cracked the tank on my Spray Coupe; tried fiberglass, JB Weld, Bondo, etc. Because of the flex in the tank, nothing would hold. Finally bolted in a couple of thin metal plates....over the fiberglass.....to hold it together; it still cracked, but only seeped a little, which at the time, I could live with. I've no doubt any of the fixes mentioned by the other posters will work on a stationary tank.

Go to your nearest small airport and get some PRC1435 fuel tank sealer. If the area is clean and dry, it will stick and won't come loose.
