I'm looking for a reliable tradesperson to repair a leaking or malfunctioning toilet flush. The issue started recently and seems to cause water to run intermittently after flushing. I’d like someone who can diagnose whether it’s a faulty fill valve, flapper, or other seal, and replace parts as needed. The job is in a standard home bathroom, and I prefer someone who can bring the right parts or confirm compatibility with a D shaped flush valve. Access is straightforward, and I’ll provide a clear photo if needed. Please provide an upfront estimate and expected duration. Local, insured professionals welcome.
