Services
Drain Cleaning
Our drain cleaning specialists use professional-grade Spartan equipment to clear blockages caused by roots, collapsed lines, and debris. Combining traditional methods with hydro-jetting technology, we ensure thorough interior pipe cleaning for commercial properties. This non-invasive approach minimizes disruption while maintaining system integrity for HOAs and industrial clients.
Hydro Excavation
Hydro excavation safely exposes underground utilities using high-pressure water and vacuum systems. Our PG&E-approved nozzles handle water mains, sewer lines, and fire line services up to 12" diameter. With 800-gallon capacity equipment, we complete large-scale projects efficiently without traditional excavation risks or disposal concerns.
Fire Line Repairs
We maintain and repair fire protection systems for commercial and industrial buildings. Our licensed technicians handle backflow devices, fire department connections, and pressure isolation valves up to 12" size. Regular maintenance ensures emergency systems remain fully operational and code-compliant for institutional facilities.
Backflow Prevention
California-mandated annual backflow testing ensures potable water protection. We install, test, and repair various backflow preventers with vandal-resistant options available. Our dedicated service vehicles carry common parts for emergency repairs, providing 24/7 availability for critical water safety needs.
Pipe Sleeving
Point repair technology fixes localized pipe damage without excavation. Using glass-reinforced fabric and silicate resin, we restore concrete, clay, and PVC pipes to exceed ASTM structural standards. This trenchless method offers cost-effective solutions for sewer and stormwater systems in commercial environments.

Bonetti Plumbing crews have been repairing a problem in my complex for the last couple of weeks and are doing seriously amazing work - everything is nearing completion and the walkway back to my home has been redone to look even nicer than before their work started. Not sure which neighbor had the plumbing issue, but community living means it affects everyone until the repairs are done. Mike and Richard have been nothing but professional and courteous every time I've walked by; and their work is outstanding. "Essential workers" is a phrase used a little too loosely right now, in my opinion, because resolving plumbing issues seems extremely essential to me - even though you might not agree, until the issue is on your property.

Report
Made appt. for closest asap (two days). Guy came out and diagnosed a leak in my kitchen faucet hose. He wanted to charge me over $400 for a replacement (whole) faucet. ONLY the hose needed to be replaced (which I called Moen/manufacturer w/lifetime wty. so they mailed a new hose days later). I asked him to duct-tape the hole in the hose as a temp fix and then I fixed/replaced the hose when it arrived.
They held my check for $179.50 (ie. didn't cash it?) and then sent me a bill for the repair? Called for Dan Bonetti/owner (at the recommendation from answering service - who were pretty rude!) and ended up leaving message on his voice mail. Waiting for reply? 5-days later, Diana calls to tell me they "found my check"?. Yikes?
