The Tank
I bought two 1550-gallon polyethylene tanks that I found on Craig’s list. I bought both for $450, which is about half of what one tank costs. Both tanks needed a little repair, but it was still a good deal. This post covers how to repair a crack. I’ll do another post in the future on how to repair a hole or gouge.
The Crack
The crack that I’m working on looks like it happened by an object hitting the tank and creating the crack with one half of the cracked piece knocked inward.
Clean
The first step was to clean the tank. I did this with a brush, water, and mild dish soap. I washed the outside of the tank just like I would a car. This prevents dirt and debris from getting into the repaired area. On the inside, the tank had some sand in it.
Level the Crack
The next step is to level the crack. Two pieces on either side of the crack do not line up, so I stuck a screwdriver in the crack and pried the inner piece out to line up with the outer piece.
The Welder
They make a kit for welding polyethylene. I bought my kit from Amazon and it cost just over $100. I’ll include a link to that below. The welding kit is like a big hot soldering iron with sticks of polyethylene that you use to fill in gaps.
Make a V
Plug the welder in and let it heat up. Then use the tip of the welder to melt the polyethylene on both sides of the crack, forming a “V” shape.
Fill the V
Then use the welder and supplied polyethylene sticks to fill the hole in the “V”. Be sure to get it hot enough to melt into the existing sides of the “V”.
