Can you go from 1.5 PVC water 2?

It seems like your question might be incomplete or unclear. If you're asking whether you can transition from 1.5-inch PVC water pipe to a 2-inch PVC pipe, the answer is yes. You can use a reducer fitting to connect the two different pipe sizes, ensuring a proper seal and alignment. Just make sure to follow local Plumbing codes and guidelines for a secure installation.
