Help with bulkhead

[codydemmel4]

Hello Everyone,

So I got this overflow from a fellow reefer for a very good deal, however the dude put the bulkhead in backwards. It is an Eshopps PF-300

The space it is in is only 4 inches long and 2.5 inches wide. The bulk head itself has only like .5 inches on each side long and pretty much zero space wide.

I do not care about ruining the bulkhead, I just dont wanna break anything in the overflow (its acrylic).

Any ideas at all?

I would greatly appreciate any help or maybe if I could leave it like this and somehow make it so I can attach a pvc/tube safely to the wrong end?

Thanks

If its glued and holds water, I would not worry about it. If not, take it out and turn around. Make sure the gasket is on the wet side.

Problem is I am asking for some suggestions on how to take it out, it is in such a tight spot. It does hold water and all of that. How would I make a safe connection though since I can not screw onto the bulkhead?

First, the gasket goes on the FLANGE side, doesn't matter if that is inside or outside the tank. I have a 75g that ran as SW for two years and then FW for another two where two bulkheads in the back glass were mounted flange side out. No leaks the entire time.

If someone used silicone on the thing, they obviously didn't know how to properly install a bulkhead fitting. The best solution I found to removing ones that are installed poorly is to cut the bulkhead apart. If you have a Dremel, cut the flange off from the inside of the fitting outward. Take small cuts until it comes off. Once the flange is gone you can push the remainder of the bulkhead back into the box. Clean off all the surfaces really well before you try to install a new one.

HTH,

HTH,

Thank you, when you had the flange side out how did you make sure the tube/pvc pipe was safe and wasnt going to come undone?

I used threaded bulkhead fittings. That and thread paste ensured it didn't leak. If I were to use socket fittings they would be glued in.

[phillrodrigo]

That is a slip bulkhead. The threads on the outside are only for the nut that holds it in place. You need pvc primer and glue to hold the piping in place

Can you not get your fingers onto the nut inside the box and simply unscrew it? Agree that a bulkhead installed 'backwards' is no problem as long as the gasket stays with the flange. I do this all the time if I'm looking to save a little space. I confess that I do occasionally use some silicone sealant on my bulkheads - yet to encounter any problems with this approach (other than it being a bit trickier to remove down the road) - usually where they are likely to get bumped on occasion.
