Leaking Pipes in basement!!!!!!
If it is leaking at the fittings (aka joints, aka connections, aka couplings or Ls or Ts or whatever), as advised, you need to unplug or turn the breaker off to the pump, drain the water down on the supply side to relieve the pressure, and cut-out (hacksaw) the leaking parts.
Dry and sandpaper the outside ends of the pipes and inside the ends of the new fittings. Use PVC primer and then PVC glue on the sanded areas, and push and twist (quarter-turn will do) them together. Hold the fitting tightly in place for a few seconds until it bonds good.Make the3 pipe and fittings all back up to roughly du0plicate what was leaking and let the glue dry as directed on can, and you should be premanently done...correctly.
