Terrible Advice Tuesdays: To ensure your bulkheads won’t leak, glue them to your tank with PVC cement.
The rest of the story: Bulkheads (also known as tank adapters) are specifically designed to form a water tight seal with your tank when they are properly installed.
Proper installation instructions include:
- making sure the mating surface is clean
- putting the rubber o-ring between the flange and tank (not between the tank and the nut)
- making sure the hole is the proper size for the bulkhead (if the hole is too big, then the bulkhead will likely leak)
Notice how there is no mention of PVC cement in that list? That’s because it isn’t needed! Also, if you do glue your bulkheads in place, the only way to get them out will be to cut them out piece by piece. This will be a big PITA and could ruin your tank as the bulkhead will be permanently installed.
PVC glue is for plumbing parts, not for bulkheads.
