Arrived onsite and tested Backflow prevention devices. The 2” DCVA passed and the 3/4” RP passed. However the 3” RP failed the test. Customer informed me that the age is fairly new and that rebuilding is a viable option. Will email customer pricing at later time for complete rebuild of 3” RP.

Arrived on site per customer request. Upon arrival customer stated that the kitchen sink was clogged and draining slowly. Filled sink until problem was replicated. Went over pricing with customer. Used drain cleaning machine on the inside clean out located underneath the sink. Ran cable out about 30’. Pulled cable back and ran water for about 10 minutes to ensure clog was no longer present. Performed 4 drain down test. Clog is no longer present. Cleaned up work area. Thanks for choosing CPI Plumbing and Heating!
