Leaking bulkead solution?

[babnika]

if you are looking for a bit larger diameter bulk head with a thicker gasket.
You may want to look at the schedule 80 bulk heads at bulk reef supply.

not sure if changing the bulkead size is going to work they're pretty standard arent they?

i really dont think i can get a drill in there at this point and not only that i'd also have to drill through the tile and the plywood then.. its not gonna happen haha

The schedule 80 bulk heads are a couple of mm larger diameter then the abs ones commonly used & have a larger thicker gasket mite be what your looking for ?

they look great but.. i need extra long thread fittings because i'm going through 3/4 plywood as well as 3/8 tile and 1/2 glass lol

Unless you can stop the water it will interfere with curing. U could try using underwater silicone inside the tank around the outer edge. Then water pressure would push the silicone into the cracks rather than out.

Since you said the tank is plywood I would really look the hole over. If it's leakng around the rubber gasket then the wood is absorbing the saltwater and weakening as we speak.

Are you tightening the bulkhead nut onto the plywood?
