Pride Plumbing came out and replaced a leaking Zurn Wilkins reduced pressure zone (RPZ) backflow with a new Zurn Wilkins 375 model. We removed the old backflow; installed the new backflow assembly with new Bavco flange gaskets, bolts and nuts; turned the water back on and checked for leaks. We tested the RPZ assembly and it passed inspection. Pride Plumbing filed the appropriate certification paperwork with the county.
