You don't think about your water heater until the moment you need it — and it isn't there. A cold shower on a Monday morning, a dishwasher that won't sanitize, or a puddle forming under your tank are all signs it's time to call someone who knows what they're doing.

​

With over 20 years of experience serving San Jose homeowners, One Time Plumbing Inc. has diagnosed and fixed virtually every water heater problem that exists. We work on all major brands, all fuel types, and all configurations — and we'll give you a straight honest assessment: repair it, or replace it, and exactly why.

​

Many issues — a failed thermostat, a burned-out heating element, a tripped reset button, or a deteriorating anode rod — can be repaired quickly and affordably. We carry the most common parts on our trucks so repairs often happen the same day you call.

​

If your tank is over 10 years old or repeatedly causing problems, replacement is usually the smarter investment. We install all major brands and can have a new unit running in most cases the same day. Tankless systems heat water on demand, eliminate standby heat loss, and can last 20+ years with proper maintenance — one of the best upgrades a San Jose homeowner can make.

​

We service traditional gas and electric tank water heaters, tankless and on-demand systems, hybrid heat pump water heaters, and commercial water heaters.
