Plugging small hole in acrylic
I have an acrylic tank with a rear overflow box in which was drilled a small hole -- maybe with a 1/4 or 3/8 bit. Small hole. It's about 1/2 down the overflow. Don't aske me why. It's not a problem for me, because I use the drain in the overflow for a closed loop not a sump.
The overflow, however, also has a second hole in the bottom that currently has a plugged bulkhead. I'd like to use that for a return (that will then go up over the top with pvc.) In short, I have to do some work inside the overflow box and would like to drain it without draining half the tank. Is there something I can use to plug that hole for a day or so while I work down there? Anything more permanent? Way too small for a standard bulkhead, I think. Can I make a DIY bulkhead/plug for a small hole? |

Could you just stuff Aqua-mend epoxy into it?

Is a simple rubber stopper out of the question?

A more permanent solution would be to cut out a small piece of acrylic and glue it one with acrylic glue, you'd have to get the area clean and dry though.

Thanks all. I was looking for a way to do it without draining my tank. It would require about a 50 percent water change to get it dry.
What is acrylic glue? Is it like silicone? The problem with trying epoxy or something else is that it will be a real drag if it fails in the middle of the project! |

I use "Weld on" for acylic projects, I like weld on 16 because it's a lot thicker than weld on 3 or 4 and will fill any gaps that I didn't sand down perfectly. It melts the acrylic chemically and joins the two pieces into one creating a permanent bond.

Sounds good. How long until I could add water back in the tank?

The tube says 24 hours to cure, but I usually wait a couple days before pressure testing.

i can't say for sure without knowing the size of the hole. but possibly you could tap the hole and screw in a small pvc plug.

Do you want to re-use this hole, once the maintenance task is complete? Perhaps a picture would be useful

If I'm understanding you correctly, you could plug it with some plumber's putty (something that is safe in the water) on the wetside and then glue a little piece of acrylic on the otherside (in the overflow) which you could be dry.

I had to seal drains in my sump tank and I used weld on with a piece of acrylic and it fixed the situation.
