    ....... I don’t know how many times I read put the gasket on the flange side.
    ....but I wasn’t paying attention and put it on the nut side inside the QT. Wrong. Just didn’t feel natural to put the gasket on the outside.

    Of course worked great when I put it on the flange on the outside.
    Easy fix for the QT before I started plumbing the DT.

    If only I actually read the original post correctly. Regardless nice thread, thx.

    I need help!

    So I have a overflow box and an external box (with which to install a bean animal drain)

    The internal box is very slim which means the bulkhead (1.5” ABS) can only outside in- (but being inside the tank)

    I know to put the gasket on the flange side which I did, but the bulkhead is definitely leaking. Originally there are 2 gaskets and I used both and then removed one- still leaking. I can only hand tighten (a little more with some help) so I doubt this is an over tightening problem.)

    These bulkhead had been in use for a couple of years so perhaps the gaskets needed replaceing?

    I also know that the plumbing is hanging off the overflow box a bit- I put in mounting brackets, but not sure how to make sure the bulkheads are not being pulled, any tips?

    I always make it a practice and this should work. Place AQUARIUM silicone on both sides and let it dry at LEAST 4 hours (or more and worth the wait). The silicone will act as a new gasket and seal it nicely and easy to scape off if removal is ever necessary

    Okay well after I install the new bulkheads if it doesn’t fix the leak I will use the sealant.

    Here is another question- glassholes.com on their instructions has using gaskets in both the nut and flange side- is that what I should follow?

    Flange side is all that is required. I too use glassholes

    So I replaced the gaskets, and while I think one of the bulkheads no longer leaks, one still does. I can’t replace the full bulkhead as the original is much shorter than the ones from BRS (longer won’t fit the 2 boxes).

    Any suggestions?

    Cut the new bulkhead shorter. I've done it before with no problems

    A couple of questions:

    I know to put the gasket on the flange side, but should i try a second gasket on the nut side? or will that just make things worse? And how about using 2 gaskets?

    If i do cut the bulkhead- what should i use? I usually use compound miter saw, but not sure how ABS will deal with it, and how to claimp it down. Should i just use a hacksaw?

    I cut mine on a tablesaw. No problem with the ABS

    Any thoughts on doubling the gaskets or using a 2nd gasket on nut side (inside tank)

    one more thought- the back of the glass is painted. now the prior owner was able to get a seal on the old bulkhead even with the pain, does it make a difference though that i am now trying to use an overflow box? (and there is more surface area between the box and the glass? or should the seal with the bulk head still be enough to prevent the leaking.

    Btw when i say leaking, it mean that water comes out from between the box in the back (tiny drops at a time, though steady).

    EDIT FINALLY figured it out.


    I am a dum dumb.


    The second gasket needed to go between the glass and overflow box on the outside, I had put the second gasket on the nut inside the inside overflow.

    The reason the OP said not to use silicone was probably because you shouldn't have to....if everything else is right. Silicone wont' hurt anything..but getting it in the threads could make it difficult later.

    As for which side to put the gasket, I always remember it because rubber grips....and if it's on the nut side, it's harder to tighten the nut...which you don't want. You want the nut to slide easily against the glass so you can get it tighter.
