A slow-draining bathroom sink at a Renton home turned out to be more than a simple clog. Trusted Plumbing & Heating was called to investigate the backed-up main-floor bathroom drain and attempted to clear the blockage by running a cable through the existing 1.5-inch galvanized drain line. During the service, our team discovered heavy rust buildup inside the sanitary tee fitting within the wall, which was restricting the flow of water through the drain. Given the condition of the existing galvanized piping, our Renton plumber recommended replacing the affected drain line running from the upstairs area into the basement. By replacing the deteriorated section, it should provide a reliable long-term solution and reduce the likelihood of recurring drainage problems.
