I noticed a small leak coming out of the edges of one of the plugs in the stock tank. It seems like the rubber area that surrounds the circular plug has a small leak somewhere. Would it be possible for me to patch the hole with some type of sealant? If so, what would be the best to use?

Thanks!

I patched a small hole in my preformed pond with aquarium sealant and a piece of plastic that i bought at lowes. So far so good. knock on wood!!

^ did you patch it on the inside or outside of the pond?

my leak seems to be coming from the outside.

Is it leaking from the plug or gasket?

I recently bought another stock tank (used) and the previous owner made his own gaskets that he said were better than those that came with the tank. He used what appears to be the same kind of rubber that the original gaskets were made of (I've got both).

If it's the plug, perhaps the teflon tape on it has become too worn. If you can check it and it's worn or coming off, get some teflon tape and reapply it.

If it isn't the actual tank that's leaking, I wouldn't seal up the plug. There are kits I think you can buy to replace the drain plug if something's wrong with it.

i patched mine on the inside and put rubber and plastic over it then put glue on the outside since it was going to be burried in the ground. I actually had 4 holes cause mine was hanging as a display, dont think it leaks anymore but water does eveporate probably from the heat and sun. I used aquarium glue, it was in a small blue and grey tube I believe. I wasnt stingy with the glue either.

I just set Roca up in a 100G stock tank. I did a leak test first and, like you, found that there was a slow leak from the drain plug. I used some aquarium safe silicone (GE Silicone I Window and Door) and liberally applied some to the threads on the plug before threading it back in. I let it cure for two days and have been leak free ever since.

If you apply teflon tape to the threads on the plug, it should fit really snugly and there shouldn't be any leaking. Personally, I like to be able to remove those drain plugs, especially for a good cleaning and rinse. (I don't have the tanks in the ground and they're taken in for the winter.)

The silicone sealant isn't permanent. It can be removed, it'll just take a big wrench.

thanks for all the responses everyone!

ill definitely give these options a shot
