My water system recently developed a pinhole leak in the pipe from the pressure tank tee to the pressure tank. The tank is an Amtrol WX-203 and is over 20 years old, so I've decided to replace it with an identical one, along with the associated fittings. I've attached a picture. The gray putty and pan are part of a temporary patch. The left side goes to the outdoor well pump and the right side goes to a water softener system. The left side has a PVC(F) to brass/copper (M) transition. The right side goes to a ball valve with a (F) threaded connection to PVC (M) transition. All piping is 1".
The replacement tank tee I have has threads on the outside and inside, so it could make a 1" or 3/4" threaded connection.
I've read that transitions from PVC to copper/brass should be male PVC to female copper/brass. With the PVC part on the outside, it can crack due to flexing over time. If I change the left PVC to copper fitting to a male PVC to the inside threads of the new brass tee, this means the PVC necks down to 3/4" briefly. I've also read that you should never neck down the pump to tank connection below 1" to minimize friction.
Would it be a problem using a 1" to 3/4" PVC to male threads adapter to connect the left side, due to friction? If so, what is the best way to do this? Thanks for any assistance.
