So I'm in the plumbing phase, I'm trying to see if the seal on the tank's bulkhead is good so I pour water in the overflow and hear water running out of it below, I'm dumbfounded, checked the washer and tighten the screw just a tad and proceed to poor more water and sure enough water comes pouring out... After a long thought process I realize I didn't place the durso in so the water is going to naturally pour out :-[ ;D
