Not sure what's wrong? We'll find it. Our diagnostic services include video pipe inspections, moisture detection, gas leak testing, and certified backflow preventer services — so you know exactly what you're dealing with before any work begins.
A plumbing inspection before you buy a home costs a few hundred dollars. Discovering a failing sewer line after you close costs tens of thousands. A second opinion on an $8,000 quote from another plumber might reveal that half the work isn't necessary. Diagnostic plumbing isn't glamorous — nobody brags about their backflow test at a dinner party — but it's the work that saves people the most money and the most stress.
We run sewer scopes for home buyers, pressure-test water lines, inspect gas connections, certify backflow preventers, and perform full plumbing evaluations for homeowners who just want to know where they stand. We also offer something simple but rare: a second opinion service. If another company has quoted you major work and something doesn't feel right, bring us in. We'll run our own diagnostics, show you what we find, and give you an honest assessment. If the other plumber was right, we'll tell you that too.
Our diagnostic work exists to give you information, not to generate a sales pipeline. You'll leave every inspection knowing exactly what your plumbing needs — this year, next year, and five years from now.
A sewer scope before closing can save you $20,000 in surprises. The best plumbing investment is the one that buys you certainty.

“Max did such a great job with the install of our Cloud RO system. He was efficient and explained everything very clearly. This was a system that we purchased and hired Pioneer to install for us. Max had experience with installing this system specifically and was very positive and knowledgeable. He was even so kind as to take the boxes out for us. It was nice to just have it all taken care of in a matter of an hour by a professional. Highly recommend!”
