Synergy reef overflow

[pserelis]

Does anyone have any experience with this kind of bulk head ? Tanks been dry for a while. Leak tested it and have a small drip by the overflow. Wanted to change the gaskets but can get the bulkhead to loosen. Any advice ?

I’ve had my best luck here using a large set of channel locks, or a strap wrench on each of these nuts… be careful though, these overflows are very fragile! — I definitely cracked, and had to subsequently repair mine while also doing a gasket swap!

(Worst-case, you can get the tip of a flat head screwdriver on one of those tiny nut ridges, and tap the screwdriver with a hammer to start spinning the nut loose… this is a last-resort, as there is definitely risk of damage!)

Looks like they've been salty before....maybe a little vinegar (and time) could loosen things up if they are cemented with a layer of calcium?

The idea to tap with a screwdriver/hammer is a good one, BTW....but you have to be gentle and careful in your tool placement.

As long as you are both gentle and careful, there should be almost no risk since the force being applied is A) small, and B) being applied tangentially to the bulkhead, not being directed at the tank OR the bulkhead. Very targeted/precise.

Remember, "tap." Not "bang" and not "pound." :) And remember your righty tighty-lefty lucy rule!! :D

Should I plug the overflow drains and fill it with water and vinegar to let it soak for a while ? Think that would help ?
