    Pipe size transition

    Simple question here. I am preparing to put in an SWG that has 2" ends. I have the bushings to go down to an inch and a half on both sides. On the output side I have the flow switch with the T connecting to the SWG via 2". On the other end of the T I have the bushing going back down to 1 1/2. I had planned on going into the SWG with 1 1/2 as well but am going to put a check valve in just before it. Since the check valve will do both I though about going into the valve with 1 1/2 and going out at 2; which will go into the SWG natively at 2. It doesn't seem like this will have any impact. I originally thought about going in and out of the valve using 1 1/2 but figured I could save a bushing by utilizing the fact that the valve will do both.

    You are not 100% clear but you should be ok. Just make sure you have unions on either side of the SWG that've have ample clearance.
