A failed water heater is one of the most disruptive plumbing problems a homeowner or property manager can face. When you turn on the hot tap and nothing comes out — or the water runs cold within minutes — the cause could be a failed heating element, a tripped thermostat, a burned-out pilot light, or a buildup of sediment that's insulating the water from the heat source. In many cases, a repair is all that's needed. In others, the unit is simply past its useful life and replacement is the smarter call.
We service all types of water heaters: standard tank units (30, 40, 50, and 75 gallon), tankless on-demand systems (gas and electric), and heat pump water heaters. Before recommending repair or replacement, we diagnose the actual problem — we don't push replacements when a repair will do the job, and we don't patch a failing unit that's going to leave you without hot water again in six months.
For rental property owners in the College Area near SDSU and throughout Chula Vista, a water heater failure needs to be resolved the same day. We carry common tank sizes on the truck and can often complete the replacement in a single visit, coordinating directly with tenants so you don't have to.

Repair vs. replacement comes down to age, condition, and the nature of the problem. A water heater under 8 years old with a failed element or thermostat is usually worth repairing — these are straightforward fixes. A unit over 10–12 years old, especially one that's leaking from the tank body, producing rusty water, or making loud rumbling sounds from sediment buildup, is typically at or near the end of its life. We'll give you an honest assessment and let you decide.
All installations are permit-compliant and meet California code requirements, including seismic strapping. We work with all major brands — Rheem, Bradford White, A.O. Smith, Navien, Noritz, and Rinnai — and can source the right unit for your home or rental property.

Why Choose A Pro Plumbing
Frequently Asked Questions
Should I repair or replace my water heater?
If your water heater is under 8 years old and the issue is a failed element, thermostat, or anode rod, repair is usually cost-effective. If it's over 10–12 years old, leaking from the tank body, or producing rusty water, replacement is typically the better investment. We'll give you an honest assessment before recommending either.
How long does a water heater replacement take in San Diego?
Most standard tank water heater replacements take 2–3 hours. Tankless installations typically take 3–5 hours depending on venting and gas line requirements. We carry common sizes on the truck so same-day replacement is often possible.
Do you install tankless water heaters in San Diego?
Yes — we install and service both gas and electric tankless water heaters. Tankless units provide on-demand hot water and can reduce energy costs, but require proper sizing and venting. We'll assess your home's needs and recommend the right unit.
