bulkhead leak
Tank leaked, I got the tank changed over. Lost 5 fish and some corals.
One of my bulkheads is leaking. Do you think I can put some silicone around the bottom of the bulkhead? Thanks Steve No sleep in three days.

Can you tighten the jamb nut, or is it overtightened??

As long as the glass is clean most bulkheads should seal hand tight, if not you may need a new gasket if it is possible to remove the bulkhead in your configuration you can get gaskets at aquatic ecosystems for a few bucks. Silicone may work but I think theres a better fix in most cases

I've found that having another person push down on the top of the bulkhead (tank side), while you tighten up the nut, fixes this problem. Sometimes all you need is just the sightest turn to stop a leak.

Good, hope it works for you. Nothing is worse than a leaky tank!

Be careful, you can crack the bulkhead by overtightening it; as a general practice when I put my bulkhead in I put a small layer of silicone on the gasket that will go against the glass and I put a thin layer on the threads of the bulkhead instead of using teflon tape. It works well and I have never had a bulkhead leak using this. With that said, I did have a bulkhead leak from overtightening it and cracking it; plus in a smaller tank, I cracked the glass by tightening a bulkhead. Also, if you overtighten a bulkhead you can cause the gasket to stretch and move out of position and actually slip over the bulkhead.

Try some Leak Ender 2000, Then order a new blukhead, plan a drain, replace and fast refill.
in the mean time, rig up a way with a plastic tarp or bag to reclaim the water, and empty the bucket every couple hours... or how ever often... I have found that some vaseline (jelly) on the rubber seal at install, the bulkhead seals without being cranked so tight... and... 2 out of 5 people intsall bulkheads incorrectly. the seal goes inside the tank. The NUT on the outside. and only finger tight. I was even at an experience friends home, and after examination, his were backwards as well. Good Luck. |

You should NOT need silicone on a bulkhead, nor do you need sealant on the threads. The GASKET sandwiched between the GLASS and FLANGE is what stops the water. The threaded portion and nut do nothing to stop water, and if you are using sealant there to stop water, then you have other problems.
Bulkhead gaskets need to be hand tight than 1/4 to 1/2 turn with a suitable tool (channel locks, etc). The most important part that people seem to miss is that the bulkhead IS NOT designed to support plumbing!!!! Plumbing IS NOT DESIGNED to support itself! You need to build supports, use plastic hangers, etc. Again if properly installed and the plumbing is properly supported, your bulkheads will not leak. Quote:
The only thing you need to be aware of is that on a plywood tank, with the flange on the outside and holes that are not sealed all the way through, water will contact the wood core as the gasket and flange are not in the inside of the tank. If this does not make sense, please ask. Bean |
