"We will be using Schmitty's Plumbing for all of our plumbing work from now on! We were able to get an appointment quickly, and Brian was on-time, pleasant, and professional. He was clear upfront about costs and options, explained the work that was needed, and quickly made the needed repairs at a reasonable cost. We are very happy to have found a plumber that we have confidence in."

"The employees were professional and got the task done. We later learned that there was a mistake in installation of the new spigot. We promptly called the company who sent an employee out the next day and fixed it. We all make mistakes. So nice to work with a company that simply owned up to it, corrected it, and did not push back on us. Despite the mistake, we will choose them again for our plumbing needs."

"The estimate provided a clean and competitive estimate. After property owner decided to hire the company, job is scheduled to start a few days later. This is very impressive in consideration of busy season in the summer. The plumbers took a few days to work thoroughly on all items to bring all the plumbing to code. The owner has personally waited for county inspectors twice at the job site. The county inspector commented the job was performed very professionally. Love to refer Knockout Plumbing to friends."

FAQs for plumbing projects in Mercer Island, WA

Schedule a plumbing inspection every one to two years to ensure your system is in good working order. Regular inspections can help you catch minor issues before they become costly problems, like major water damage repairs. You should also consider a plumbing inspection when buying or selling a home or if you notice signs of a plumbing issue. Staying proactive with maintenance can save you money and stress in the long run.

A plumbing inspection for a standard one-story to two-story home takes between two and three hours. For larger residences, historic homes, or rental complexes, a complete inspection requires a full-day commitment of eight hours. However, this does not account for any necessary repairs that your plumber might find, so it’s best to set aside additional time during the inspection in case an unexpected repair comes up.

When built with quality materials, your plumbing system endures for decades. CPVC, brass, iron, and steel provide reliable service for 50 to 70 years, while copper extends durability up to 100 years, and PEX maintains performance for 80 to 100 years. Maintaining this system with regular inspections and prompt repairs guarantees long-term efficiency.

You should repipe your home when your plumbing exceeds its expected lifespan or uses hazardous materials like lead, polybutylene, or galvanized steel. Persistent leaks, corrosion, and compromised water quality signal that your existing piping no longer meets safety standards. Repiping eliminates potential health risks and prevents extensive water damage.
