PLUMBING SERVICES
Our Plumbing Services in Palo Alto
From sewer line inspections and water leak detection to kitchen plumbing and water heater replacement, United HVAC, Plumbing & Electrical provides services for homes with different plumbing systems, layouts and installation requirements.
COMMON PLUMBING ISSUES
Common Plumbing Problems in Palo Alto
Older plumbing, concealed pipe runs and changes made during past renovations can complicate repairs. These are three situations where finding the cause matters.
Sewer Backups in Older Homes
Recurring backups may point to root intrusion, deteriorated pipe joints or restrictions farther along the sewer lateral. Cleaning without identifying the cause can provide only temporary relief. After the City’s required safety check, a sewer camera inspection can help identify visible damage and guide the next step.
Hidden Leaks in Slab-Foundation Homes
Some Palo Alto homes, including Eichler properties, have plumbing or radiant heating components beneath concrete floors. A damp spot or unexpected water use does not automatically identify which system is affected. Our leak detection and repair service focuses on locating the source before recommending invasive work.
Water Heater Replacement Decisions
When a water heater leaks, produces inconsistent hot water or approaches the end of its useful life, homeowners may need to compare repair and replacement options. Equipment type, installation space and Palo Alto permit requirements all matter. We assess the existing setup and discuss suitable water heater services.
Plumbing Considerations in Palo Alto
Palo Alto’s residential properties range from historic houses in Professorville and Crescent Park to mid-century homes in Midtown, Greenmeadow and Fairmeadow. These buildings can have very different pipe layouts, access points and plumbing materials, especially after decades of remodeling.
Eichler homes deserve particular attention when work involves concrete slabs or radiant floor heating. A suspected leak may require checking which system is affected before planning repairs that could disturb the floor. In other homes, deteriorating water supply piping may make whole-house repiping worth considering.
Sewer laterals are another concern in established neighborhoods. If backups keep returning, the problem may involve roots, pipe separation or deterioration underground. We can evaluate the available evidence and explain whether sewer line repair is appropriate.
We serve Midtown, Old Palo Alto, Professorville, Crescent Park, Barron Park, Greenmeadow, Fairmeadow and College Terrace. For heating, cooling and electrical services, visit our Palo Alto service area page.
Repair or Replace?
A single leaking connection or isolated pipe defect may be repairable without replacing an entire system. Multiple leaks, deteriorated piping or recurring structural sewer problems can change that decision. We review the condition and accessibility of the affected plumbing before recommending the scope of work.
Palo Alto Plumbing Permits and Sewer Guidelines
Water heater replacement
Palo Alto requires a permit for water heater replacement. Certain gas-tank replacements and qualifying heat pump water heater installations may use the City’s instant permit process. Eligibility depends on equipment and property type.
Water line repiping
The City offers an instant permit option for eligible interior water-system repiping in detached single-family homes and duplexes. Sewer line work is excluded from that specific permit category and may require a separate application.
Sewer backups and lateral responsibility
Palo Alto’s sewer lateral rules depend on the presence and accessibility of a City sewer cleanout. When a qualifying City cleanout exists, the City generally maintains the lower lateral and the property owner maintains the upper portion. Without one, the owner’s responsibility may extend to the public sewer main.
For sewer backups or suspected public sewer issues, contact the appropriate local utility department before arranging repairs.

Frequently Asked Questions About Plumbing in Palo Alto
United HVAC, Plumbing & Electrical can assess plumbing problems in older homes and properties with slab foundations. In Eichler homes, it is especially important to understand the existing plumbing and radiant heating layout before recommending work that may affect the floor.
Stop using fixtures that send more wastewater into the affected drain. The City of Palo Alto advises calling Utilities Dispatch before attempting sewer line clearing or repair, so the line can be assessed for safety.
Responsibility depends on the location and accessibility of the City sewer cleanout. When a qualifying City cleanout is present, the City generally maintains the lower section and the property owner maintains the upper section. Without an accessible qualifying cleanout, the owner's responsibility may cover the entire lateral.
Yes. Palo Alto requires permits for water heater replacements. Some qualifying gas and heat pump water heater projects may be eligible for the instant permit process, while other installations require a regular application.
Whole-house repiping generally requires a plumbing permit. Palo Alto offers an instant permit option for qualifying interior repiping projects in detached single-family homes and duplexes. Work involving sewer lines or other excluded conditions follows a different process.
Costs depend on the plumbing problem, required materials, access to the affected pipes and extent of the work. A localized fixture leak involves a different scope than concealed pipe damage or sewer lateral replacement. We assess the problem and explain the recommended work and pricing before starting.
