Unexpected events always happened to me. When the plumbing is all done, we filled in the water, and with a switch of the button at my American DJ power panel, we started the pump. Everything went on fine. We ran the pump for 20mins and don't see any leaks. It was around 9pm and we decided to turn off the pump, put back the trim and go for dinner.
Coming back from dinner, I saw a small pool of water on the left side of the stand.
I rush out to get a flashlight and lo and behold, the return 3/4" bulkhead crack on me and the water back siphon. I adjust loc return above water to stop the back siphon, put a bucket below and unscrew the union and the male adapter to the bulkhead (I use threaded bulkhead). But as you guess it, how am I going to change out the bulk? I am not willing to remove the trim again. Nor will I want to remove my plumbing, ldrain the water and lift up the tank!!!
I drained the water in the overflow and went ot bed. The next morning, I went to Lowes, HD
, Ace HW, NAPA and could not find any wrench that I can work from the bottom. I had my last stop in Sear Hardware and to my big sign of relief, I found the "miracle' tool that saved my agony. It allows me to work from the bottom. It does come with sizes that fit the 3/4" bulkhead and the 1" bulkhead. They are very costly though due to the odd size, but it is worth it.
