Removing an Overflow?

[texhorns98]

Anyone ever done it? I have two corner overflows and I really only need one.

I did it once or twice..lol
Easy to do if you know what you are doing.

It can ve done with bulkhead fittings BUT then that area will always be a source for a potential leak. FWIW. Good luck!

IMHO, I think that it's not worth the trouble, risk of leak, or unsightly plugs that you will have to use. Depending on how much flow is generated by your return pump and the size of the overflow pipe, limiting the drainage system to one overflow may cause your system to gurgle.

A possible solution would be to increase the size of the remaining overflow plumbing, but that will probably require drilling tempered glass... we know how that ends.

At the very least, you should try to determine if the one overflow can handle the amount of water flow you plan to use. I'm no help in determining that. Maybe someone else will chime in here.

The plugs and bulkheads would be covered by sand, no? I'll have to check my flow rate, it's an Eheim 1262. I have a ball valve on one, so I can shut it off and check. It would gain me 8 inches of view from the living room side.

I wouldn't be concerned about the bulkheads leaking if done properly .They would be no more of a weak point that the aquarium seams. Razor blade and a sharpened putty knife is how I have removed them

I'm going to do this tomorrow afternoon. I have the plugs and figure I'll leave the plumbing in tact. That way if there's any leaks, they go right into the sump!
