holding tank leak

[Karalyn]

A rock hit the bottom of the plastic holding tank and caused a leak in my son's camper. Just wondering if anyone has an idea on how to repair a plastic tank with a crack in it??

I had a crack in my water tank on a different unit.I used liquid plastic in a tube.Worked great.

I should add that i did it too a fresh water tank----40 gals

This came up previously, and here's a link to my description of my repair: Leaking Grey Water Tank on Boler. A follow-up with a photo is a couple of posts later in the same thread. The patch is holding up fine, a couple of camping weeks and a few thousand road kilometres later.

I have used Gorilla tape to repair the graywater holding tank on our Burro. I think that the tank is made of ABS, but I think that the Gorilla tape will work on most anything. Just make sure the area around the crack is quite clean and then apply a couple of layers of Gorilla tape. This tape should be readily available at home centers, paint stores, and hardware store.

Look for a shop that can do plastic welding. There are other solutions, but welding the crack is the best.

I had a golf ball sized gash in my holding tank. I cut a piece from an old plastic cutting board that was the same plastic, and then spent some time *slowly* heating each up around the edges and then 'welded' them by smearing the soft plastic with a heated up knife. It hasn't leaked in over 2 years.

A good old fashioned soldering iron works great. Make sure it is dry first.
