Well...the tank IS full..heh. I was testing stuff. Thankfully if I have to drain the overflow and replace this bulkhead if the T+2 doesn't work it won't be so terrible. I only filled it with RO water, no salt yet.Yepp, happens to the best of us
Thankfully it's an easy fix. I watched a plumber I subbed once use the wrong pvc glue to build a whole public water treatment plant (well I didn't personally watch that part) when they released water every connection leaked and/or blew. At least you found this now not with gallons of water everywhere
I think you may be conflating standards. ABS and PVC are types of plastic and have nothing to do with the thread types they may or may not be. Typically most schedule 80 threaded fittings conform to the NPT standard. You can Google more information on that (national pipe thread). The common bulkheads sold that are made of ABS plastic should conform to that of NPT as well. However manufacturing tolerances and the difference in material types can lead to less satisfactory results. Usually plumbers putty or a quality pipe tape applied in the correct fashion can result in a leak free joint. However, for peace of mind and as dirt cheap as these bulkheads are I'd recommend getting a slip fitting on your exit side and doing a solvent weld. The end that goes to the inside of your tank can be whatever works for you. Being that the fitting is used you are taking you're chances that the threads may or may not be compromised. This advice is just my opinion based on years of general plumbing experience that has nothing to do with reefing but still applies.
Yea if the T+2 doesn't work, I'll just buy a new slip bulkhead and re-do the piping from there to the drain, nbd. Looking at the yellow tube it says its good to 100psi while the red T+2 is good to 12,000....so yea, might be the sealer. The teflon tape was applied properly, but it did tear it up. I'll report back tomorrow, thanks!
