It's pretty close between the two. I've installed more Moen then Delta in the Seattle area. The plumbers that prefer Delta are often in hard water areas. With normal water balance, I consider them pretty equal.
My plumber is against Delta stating their valves are cheap & problematic. He prefers Moen. Need your help, please, to convince my husband that Delta is a better choice. Thanks!
Thanks, Terry. No hard water problem here, but do have old pipes. Grateful for your forum. I've learned so much here.
