Pride Plumbing came out and provided cost estimates to 1) either rebuild or replace a leaking Watts LF009M2QT reduced pressure zone (RPZ) backflow and test it for recertification; and 2) trench a ditch from an existing water meter to the home and replace the black roll main outside water supply line with new black roll and PEX piping and fittings along with installing a new pressure reducing valve (PRV) and ball water shutoff valve at the water meter.
