Much to my surprise, the water company called and said they needed to upgrade the water meter. "Sure... no problem", I said. We set up an appointment, they came over, I showed them where the meter was and the first words out of their mouth was, "that's not right". Huh?? Apparently the previous owners decided it would be a good idea to plumb in the sprinkler line BEFORE the water meter. And quite honestly, I had never even noticed. (I take it the inspector didn't notice either.) So, now I'm re-doing the main line coming into the house and I'm wondering a couple of things... Since the line for the sprinkler system is plumbed in before the meter AND before the pressure regulator, am I going to have issues after I plumb it in AFTER the meter (which would also be after the regulator)? What's the right order for the regulator, meter and sprinkler line after the first isolation valve on the line coming in to the house from the street? Also, is it necessary to replace the pressure regulator? I'm not having any pressure issues. Can I continue to use the one I've got?
