Repairing leaks in evaporative cooler pan/tray

Aug 26, 2006 5 Replies

The cooler on the roof of my trailer works fine, but the pan/tray underneath it has many holes, some big enough to put my finger through. I tried fixing it by applying the stuff that is sold to repair such leaks (something like tar) to the metal and then binding it together by covering it with plastic screening. That didn't work. I guess the problem is really twofold: First, finding all of the leaks, and then patching them. Any ideas? Oh, replacing the entire pan/tray with a new one would seem to be the perfect solution, but I haven't seen such parts available on the Internet. Can they be purchased separately?

Hi, Sheet metal shop may rig one up?

To replace the pan (bottom), it has to be a replacable pan. To determine if it is, see if it is bolted to the upright supports. If there are no screws or bolts it is not replaceable. If there are, then try to find out who the manufacturer isand contact them for the replacement pan.

If you can't find a drop-in pan liner from a local store (they are getting harder to find), try a piece of sheetmetal or rigid fiberglass. Seal around the edges with a "plumbers epoxy" putty. If you put the patch on the inside you will have to clean the pan where patch edges will be so the epoxy will stick. To cut a hole for the overflow tube, use a hammer and chisel or screwdriver and punch around the area where the hole needs to be. Seal this hole with epoxy putty.
