Unfortunately I wasn't able to attend the last
TRL, but I did listen to it. I have an important follow up to the "what side does the washer go on" topic.
IT GOES ON THE FLANGE SIDE OF THE BULKHEAD!
This is absolutely critical to having a leak free system. You can install a bulkhead two ways, with the flange (wider part) in the tank, or out...doesn't matter. If you place the flange on the outside, but put the washer on the inside "wet" side of the tank, the water will follow the treads and leak out. The same is true if you attempt to put the washer on the outside if the flange is in the tank. The flange and washers are buddies, please dont separate them!
