Reviewed by the Rialto Plumbing Pros licensed C-36 Plumbing Contractor team · Updated February 2026
No hot water, rusty water, popping sounds, or a puddle under the tank all point to a water heater that needs attention. Our Rialto plumbers repair tank and tankless systems, replace failed units, and install high-efficiency tankless heaters — all documented and permitted to code.
Because Rialto's water averages 160 mg/L hardness, scale builds up inside heaters faster here than in soft-water regions. We inspect for scale, venting, and seismic-strap compliance so you get a repair that actually addresses the cause.
Signs your water heater needs service
- No hot water or water that never gets hot enough
- Rusty, cloudy, or metallic-smelling hot water
- Popping, rumbling, or knocking from the tank (scale)
- Water pooling around the base of the heater
- Higher energy bills or slow recovery between showers
- A unit past 10–12 years with recurring problems
Our water heaters process
- 1
Inspect & test the unit
We check the burner or elements, thermostat, relief valve, venting, connections, and anode — documenting the current condition instead of judging by age alone.
- 2
Repair vs. replace guidance
You get an honest comparison of repair, tank replacement, and tankless installation based on symptoms, scale, capacity, and your energy setup.
- 3
Code-compliant installation
New installs include seismic strapping, correct venting, a temperature-and-pressure relief line, permits, and safe disposal of the old unit.
- 4
Startup & warranty
We complete a startup and leak test, walk you through operation, and document warranty terms before final payment.
Tank or tankless? An honest comparison for Rialto homes
A tankless water heater isn't automatically cheaper or better. Capacity, gas or electrical supply, venting, water quality, available space, and maintenance all need review first. We size the system to your household demand and confirm the full installation scope before you approve anything.
Water-heater lifespan depends on equipment type, water quality, maintenance, and installation — not the calendar. With Rialto's hard water, an annual flush and attention to scale at connections can add years to a tank. When replacement genuinely makes sense, we document why.
Ask us whether seismic strapping, venting, relief components, permits, disposal, startup testing, and warranty are all included — with us, they are, and they're written into your estimate. For persistent scale, we can also pair your new heater with a water softener or filtration recommendation based on the measured problem.
