About United Plumbing & Water Heaters
United Plumbing & Water Heaters holds a 5.0-star rating across 294 reviews, reflecting consistent excellence in the Pleasanton area and throughout the San Francisco Bay Area. Based in Pleasanton, the company serves customers across multiple Bay Area communities including San Jose, Santa Clara, Sunnyvale, Cupertino, Mountain View, Palo Alto, and Redwood City. Their team handles everything from routine maintenance to complex water heater installations and emergency repairs, maintaining the high rating that has made them a trusted name in residential plumbing throughout the region.
What distinguishes United Plumbing from competitors is their comprehensive service model and commitment to same-day resolution. The company offers water heater and filtration solutions, drain and sewer services, water line and repiping, in addition to heating, air conditioning, and electrical work. Their ability to handle multiple specialty trades in a single visit eliminates the need for homeowners to coordinate with multiple contractors. Service is available seven days a week from 8 AM to 8 PM, accommodating schedules that traditional contractors cannot match.
Reviewers consistently highlight specific technicians who delivered exceptional service. Victor B. earned particular praise for replacing a leaking water heater and a broken shower faucet on the same day, then returning to install a Waterdrop filtration system, replace corroded valves, and repair a main shutoff line. Tony conducted thorough pipe scope inspections and walked homeowners through water heater replacement options. Customers also noted Grace and Lady for facilitating same-day scheduling across multiple service calls. One reviewer required a same-day technician visit when their water heater stopped working, and Viktor quickly diagnosed a closed gas valve that the homeowner had not discovered.
What Customers Say
All 294 reviews award 5 stars, with customers repeatedly mentioning same-day service availability and technician expertise. Multiple reviewers highlight specific technicians Victor, Viktor, and Tony by name, noting their diagnostic thoroughness and ability to handle multiple plumbing issues in single visits.
