Years ago I got a lift of JM pipe and found, tho the ends mated, the centers were of (IMHO) a smaller OD than the Spears/Lasco fitiings. Sent the lift back, switched to PW..problem over...now, I'm told, JM bought PW. Gluing a manifold today, I had the SAME problem, only with "PW" pipe (by JM). Any you guys have this problem? It kinda screws me & Hank, as they seem to have the market up here. Is a micrometer going to part of our tool bags.?
