Tank water heaters typically last 8–12 years, while tankless models last 15–20 years with proper maintenance. Cotati's water quality can affect lifespan — areas with harder water may see scale buildup that shortens tank life. Annual flushing helps extend your water heater's lifespan by 2–3 years.

Warning signs include rusty or discolored hot water, rumbling or popping noises, water pooling around the base, inconsistent water temperature, and a unit older than 10 years. If you notice any leaking from the tank itself, replacement is usually necessary as tank leaks cannot be reliably repaired.

Tank water heaters are more affordable upfront ($1,200–$2,500 installed) and simple to maintain. Tankless models cost more ($2,500–$4,500) but provide unlimited hot water, last longer, and save 20–30% on water heating costs. For Cotati homes with 3+ bathrooms or large families, tankless is often the better long-term investment.

Yes, Cotati County requires a plumbing permit for water heater installation or replacement. The permit ensures proper venting, seismic strapping (required by California code), gas connections, and overflow drainage. We pull all permits and schedule the required inspection as part of our standard installation.

Standard tank water heater replacement takes 2–4 hours. Tankless installation takes 4–8 hours because it often requires upgrading the gas line or adding a dedicated electrical circuit and new venting. Heat pump water heater installation takes 4–6 hours and may need electrical upgrades.
