ABS plastic - Reef Safe?

[Walter White]

Anyone know if ABS plastic such a ABS plumbing pieces are reef safe?
I need to plug a hole in the overflow of my MarineLand 60 cube and was looking to use a small 1"x"1 piece of ABS pipe for this.

Im sure its fine I just wasn't sure.

Does anyone know if ABS cement will bond with other common plastics?

Here is a picture (not my tank but some general idea). I am not using either of the circled knockout on my overflow but one was already knocked out for the lockline return (which Im not using). Im looking for something to patch it with. A segment cut from a large diameter ABS pipe seemed like the best option.

You should be fine to use ABS. If you look at a lot of the submersible pumps, float valves, and even those flow accelerators that we use on our returns...ABS plastic is a fairly common material.

As far as materials for bonding the ABS...are you looking to bond it with PVC? I unfortunately don't know of any cements that are definitely safe for potable plumbing...but they do make 2-part epoxies that would work, as well as pipe cement that works with both PVC and ABS. Finding out if they are reef safe may take some digging...but I know the stuff is available, as I've used it to before.

Im not sure what type of plastic the overflow is but that's what I would be bonding the ABS to. It dosnt need to be super strong I just want to keep fish from getting into my overflow through that knockout and want it to look good.

Hmmm what about these nitrile rubber grommet plugs? Not sure what size the holes are but........

Hey that's a great idea! They sell those at Ace. I may try that! Its somewhere around 3/4"-1" across.

Let me know it works out as I need to do the same thing myself on my overflow

Chad may have outdone my suggestion here But rather than use a questionable cement to bond the pieces, I would suggest using some plastic meshing on the back with cyanoacrylate to hold the ABS patch in place...similar to how you patch fiberglass if you've ever messed with that before.

If you go the PVC bond to ABS route, they do have a cement that will bond the 2 together at Home Depot- its next to the regular PVC cements. I was going to do it for a project, but came up with a PVC to PVC solution.
