Leak #1 just needs an elbow and a threaded PVC nipple, not a male adapter. About 5 minutes.
Leak #2 remove the couplings and stub from the tee, and everything including the elbow. Install two pieces of copper with a good ball valve and a new elbow, maybe one hour, depending on whether there are any problems removing the stub from the tee.
No different than what we run into every day, and would love to be able to charge $700.00 for doing it, although we might not get any repeat business from the customer. Your problem is calling a nationally franchised plumber/drain cleaner plumber.
