Who fixes water heaters in the Tri-Cities?
Sonlight Plumbing is an owner-operated, residential-only plumber serving Kennewick, Pasco, Richland, West Richland, West Pasco, Prosser, Finley, Burbank, and Benton City. Jose repairs and replaces both tank and tankless water heaters. Start by matching your symptom below — no hot water, a leak, or a tank near end of life all point to different next steps.
Four ways to get water heater help
Choose the page that matches the job: repair for symptoms and failed parts, replacement for end-of-life tanks or planned installs, troubleshooting for safe first checks, and tankless for tankless service or conversion questions.
Water Heater Repair
No hot water, a pilot that will not stay lit, lukewarm water, or a dripping relief valve — many problems are repairable.
Water Heater Replacement
An aging tank, rust, leaks from the tank itself, or repeated failures may make replacement the better long-term decision.
Water Heater Troubleshooting
A symptom-by-symptom guide to what your water heater may be telling you, and what is safe to check yourself.
Tankless Water Heaters
How tankless systems differ from conventional tanks, and what switching involves.
Start with the symptom
What is your water heater doing?
Tank and tankless are different systems, not better and worse
They heat water in different ways, install differently, and suit different homes. Which one fits depends on the household’s hot-water demand, the existing fuel and venting, and the space available.
Tank
- Keeps a volume of water heated and ready
- Familiar setup in most existing homes
- Recovery capacity matters when demand is heavy
- Physical footprint is larger
Tankless
- Heats water as it flows, rather than storing it
- Continuous hot water within the unit’s rated capacity
- Sizing matters, because flow rate and incoming water temperature affect output
- Installation requirements vary, including gas, electrical, and venting
Shown for orientation. Which system fits a particular home is decided after the existing setup, fuel, venting, and hot-water demand are evaluated on site.
Repair or replacement?
Repair may make sense when
The unit is younger, the problem is a specific part — a thermocouple, element, thermostat, or valve — and the tank itself is sound. Not every water heater problem means replacement. Relief valves, drain and shutoff valves, expansion tanks, and seismic straps are covered under valve and accessory repairs.
Replacement may be better when
The tank itself is leaking, the unit is near the end of its typical 8–12 year lifespan, repairs keep coming back, or the system cannot keep up with your household.
Conventional tank or tankless?
A conventional tank stores heated water and is the most common setup in Tri-Cities homes. A tankless system heats water on demand, takes less space, and can supply continuous hot water, but switching involves venting, gas or electric capacity, and sizing decisions. Each option is explained on its own page.
Tank or tankless — which is right for a Tri-Cities home?
A conventional tank costs less up front and handles several fixtures running at once. A tankless unit can offer a longer service life, avoids the stored-water standby losses of a tank, and takes less space — but it’s flow-rate limited, needs the right gas line or electrical capacity, and maintenance frequency should follow the manufacturer and the actual water conditions at the home. The best choice depends on your household’s hot-water use.
| Factor | Conventional tank | Tankless (on-demand) |
|---|---|---|
| Typical lifespan | 8–12 years | 15–20+ years with maintenance |
| Hot water supply | Limited by tank size and recovery time; can run out during back-to-back showers | Continuous while running — but flow-rate limited, so several fixtures at once can outpace a single unit |
| Energy efficiency | Roughly 0.60–0.70 UEF; loses heat keeping stored water hot around the clock (standby loss) | Up to 0.95–0.97 UEF for condensing gas models; no standby loss. DOE: 24–34% more efficient at ≤41 gal/day, 8–14% at high use |
| Space | Floor-standing tank, often in a closet, garage, or utility room | Compact wall-mounted unit |
| Upfront cost | Lower | Higher — typically 2–3× a tank, more if gas line or venting must change |
| Installation needs | Usually a straight swap on the existing setup | Gas: often a larger gas line and new venting. Electric: may need an electrical panel upgrade |
| Cold-weather performance | Unaffected — water is pre-heated in the tank | Very cold incoming water in winter lowers flow rate; units should be sized for Tri-Cities winter temperatures |
| Hard water / mineral conditions | Sediment can collect at the tank bottom; flushing frequency should follow manufacturer guidance, service history, and tank condition. | Scale can build in the heat exchanger; descaling frequency should follow manufacturer guidance and actual water conditions. |
| Best fit | Larger households with heavy simultaneous use, tighter budgets, quick replacements | Small–medium households, space-limited homes, long-term owners focused on efficiency |
A heat-pump (hybrid) tank is a third option worth asking about — it can cut electric water-heating energy use substantially. High-efficiency units may also qualify for federal or utility incentives; check energystar.gov for current programs. Figures above are typical industry ranges, not a quote.
Why an in-person evaluation matters
The same symptom can have different causes — no hot water may be a tripped breaker, a failed element, or a gas control problem. An in-person look at the unit, its venting, its connections, and its age is what turns a symptom into a clear set of options. Sonlight Plumbing walks homeowners through exactly that, with clear options before any work begins.
Local water and replacement rules
Water conditions are not identical across the Tri-Cities. Across Kennewick, Richland, Pasco, West Richland, Prosser, Finley, Burbank, Benton City and the West Pasco area, source and treatment context can vary by utility and address, so maintenance should be based on the actual water and equipment condition. Start with the Tri-Cities hard-water guide. If replacement is being considered, the local replacement requirements explain permit, seismic-strapping, and relief-discharge considerations.

How old is my water heater? Decode it from the serial number
Find the label on the side of the tank. Many labels print the manufacture date outright — check that first. If yours only shows a serial number, pick the brand and enter it below for an estimate.
This is an estimate based on published manufacturer serial-number formats. Age is context, not a verdict — condition, maintenance history, and where a problem is located matter more than the number alone. Not sure? Snap a photo of the label and send it with your message.
