Suction side Air leak from skimmer line

[wireform]

RP,
Great work there. You mention running a new line.... I'm not convinced it's at all necessary. You said yourself that you got the pump running real well at the end when you put lube on to the old fitting. That tells me your line is good . I would just plug the skimmer old threaded hole from the skimmer side, get the proper fitting and connect the new side with the original suction line. You will be good that way it seems.

Thanks. The problem is there is no room to work under there at all. The first foot of piping is all fittings and 45 degree elbows. By the time I cut it all out, the First available 2 inch pipe is tucked pretty deep in the hole which will be pretty hard to reach and also I may not be able to line it up with the new port because of the slight direction change of the pipe path and trying to cement and slip on what ever the last joint may be tricky. Running a partial new line would require more trench digging but joining the new pipe with the existing pipe in the grass will be much easier.

I cut the old pipe out and unscrewed the threaded fitting pretty easily. I may consider using the existing pipe if I can figure out how to join all the parts together. I think I may have to make a join in the shape of a letter C like in the attached photo from a YouTube clip I pulled up.
I also noticed the failed threaded fitting had almost no pipe dope on it which helps explain the leak.

Just make sure you can get that old pipe spotlessly clean and get at least a quarter turn on the fitting as it goes on. The connection to the old pipe is the most likely to leak.

Also reduce to 1.5" further back if it makes it easier theres mo need for 2" right to skimmer. The U repair is the easiest way to meet the 2 pieces.

I looked at the pipe that remains under my deck and I cut the remaining unusable joint with the intention of cleaning up the pipe and adding a new coupler to being reconnecting the skimmer. After cutting the pipe, the shifting dirt exposed more pipe deeper about another foot and there was another joint. I realized that i have no way to know if that joint is solid or has air leaks as well so I’m going with plan B or C or maybe it’s plan A. I’m basically winging this as I discover new things.
I’m going to run a new line and run it out The hole I dug, dig a new trench in the grass around the deck, then connect it from there to the existing skimmer line that leads to the pump. It’s a bit more digging but Im more comfortable going with that option than laying under my deck trying to connect fittings.

Issue has been resolved and there are no air leaks or water dripping under the skimmer. I installed a new line on the back skimmer port and capped the front one. The line line wraps around my deck in the grass. I then joined it with the existing run before it turned under the deck.
