one photo undersink shows an angled, threaded copper pipe coming out of wall-- that did not drip much the first year and a half we lived here... now it does.. it fills up that tupperware about every three weeks.. I think it is an abandoned vent line that heavily condensates in the cold air in that outside wall.. could I just connect the new trap to that vent and solve both that drip and the venting?
You see the mess- is it slop photo worthy?
The big leaks are coming at the closer tupperware-- was a little after the disposal installer screwed with it while he added that flex line, tonight it was gushing at the slip joints in the two inch horizontal section -- might have gotten bumped- when I retightened them it seemed to work for now
in the basement photos you will see they barely slopped the horizontal.. one thought is to replace all of this horizontal basement stuff with ABS or PVC along with the under sink work, possibly putting the stub up under the sink in a better spot.. tie it into the copper vertical drain further down with a no-hub connector?
you can also see another mystery angled pipe in on of the basement photos that was also occasisionally dripping- I expect another abandoned line that had condensation in that cold wall.. in my early haste i filled it with spray foam and duct taped it-- which worked? I imagine it is filled with condensation water now, but the foam and duct tape had kept the basement from water
