I have a water line 1500 feet long 3/4” PVC. Had a break a couple weeks ago and repaired the leak but flow is low now. It had a gate valve between the leak and the house. Took it out , found a bunch of pebbles in it. Flow improved but still not right. Thinking about replacing the last 500 feet of the line. Is there any harm of using 1” so that if the rest has to be done later it may all be 1”?
