How to repair a Rubbermaid stock container?

[seantOH]

I have a problem with a hairline crack in my sump. My sump is made out of two 100 gallon plastic Rubbermaid stock containers plumbed together. One of these has developed a hairline crack that is now leaking water. Has anyone repaired one of these containers? I assume that there is a compond that is reef safe and will adhere permanetly to the plastic. Any one have any experience? Thanks in advance.

Is the crack just in the plastic or is it across the hole for a bulkhead?

You can try emailing the Rubbermaid people. I have in the past and they got right back to me.

Good old silicone might work just fine.

Thanks for the replys. The crack is across the plastic and is not associated with the bulkhead. I tried silicone and it did not stick.

I am considering a 2 part epoxy but I am not sure which one. I have some Marinetex which is used for boat repairs. It seems to stick to the plastic but I am not sure if it is reef safe. Thanks and take care.

I think all epoxy is reef safe (not 100% sure though). I've used a couple types from HD and also applied a marine epoxy directly under the water. Just turn your pumps off for a while as the epoxy sets because little bits can come loose and get into your pumps.

I would rough up the sump before the repair so the epoxy will hold better.

If its splitting I would strongly suggest that you swap it out with a new one. IMO It's not worth the risk of trying to patch something that might get worse.

i would get a new one but if you really want to fix it. drain it, sand it , lay fiberglass mesh and resin on it. then your done. it will never crack in that spot again.

Try to find a place for a plastic welder to rent. It works great, comes with plastic weld sticks so the whole idea is to lay a bead like regular welding. It uses air with the hot metal element that combines to "weld plastic" works great.
