Tank Tee Question

The bladder in my water tank went bad so the tank needs to be replaced. The original tank was installed without a tee. The builder’s plumber used a combination of pvc tees and pipe to make a tank tee. I can not reuse any of the material because it is all glued in place. I purchased a pvc tank tee to use on the replacement tank. My problem is what type of connection do I use on the supply ends of the tee? They are all 1” male and I need to adapt to ¾ pvc pipe.

 

A brass reducing coupling 1 x 3/4 You could use galvanized, it costs less but will eventually corrode on the inside.
