Ace Pelizon Plumbing found master bathroom sink slow draining, will cable line through top of drain to clear line. Ace Pelizon Plumbing determined sludge was causing the slow drain. Ace Pelizon Plumbing determined guest restroom left sink backed up, will cable through top of drain to clear drain. Guest restroom right sink pop up assembly was taken apart, put back together and tested for leaks and function. Ace Pelizon Plumbing determined the kitchen sink was not spraying correctly, so we removed aerator and cleaned, also soaked pull out faucet in vinegar and tested. All areas are flowing with no back ups. Poured bio line down all drains for preventative maintenance.
