As always (we live in an old house) Knights Plumbing are our go to plumbers. Always respectful and in good moods. Today it was Victor’s turn to tackle roots in the pipes. Fast, professional and overall a great guy. He was informative without being pushy about our pipe and tree situation (we do know it’s not great) 5/5 stars. Thanks Victor

Our technician Victor did a fantastic job of running his cable and camera in our sewer line. He unclogged our blockage, fast and efficiently. He was very respectful. I would recommend this company to anyone who’s looking for plumbing services.. Leslie took our phone call and he got someone to us in less than an hour! It wasn’t expensive for the amount of work that was done .If I could give this company more stars, I would.

How Mountain House's Rapid Growth Affects Your Plumbing

Mountain House represents one of California’s newest master-planned communities, with thousands of modern homes built over the past two decades. While newer construction means contemporary plumbing systems, rapid development brings unique challenges. Many Mountain House properties experience installation issues from rushed construction, including improper fixture mounting and inadequate water pressure from undersized systems. The area’s location near the Delta brings clay-heavy soils that shift seasonally, potentially stressing underground pipes and foundations. Despite modern plumbing, Mountain House faces the same Central Valley hard water problems—high mineral content that accelerates scale buildup in water heaters, pipes, and appliances. Our experience with both new home systems and preventive maintenance makes us the plumber in mountain house homeowners trust.
