Rubbermaid stock tank drains

[mloebl]

Just curious if anyone was able to figure out the hole size for the inner bulkhead of the stock tank? I have a 100g stock tank and a few MPT fittings here for 3/4", 1" and 1.5", and it almost looks to be a 1.25". Tried some searches online, but can't find any details.

If I can't find the size, if you drilled a hole for a new bulkhead, did you have to do anything special to seal it, or was the rubber gasket enough?

Thanks!

Drill a new hold, plug in a 1.5" or 2" bulkhead and dont look back. the bulkhead gaskets will hold fine. Just make sure the bulkhead does not fall on one of the curves steps the tank has on it's ridges/sides.

The original drain is not any standard pumbing size.
