Homeowner Plumbing Guides
Plain-English answers for Tri-Cities homeowners. Guides reviewed by Jose Hernandez, the owner, say so and carry the review date; any guide awaiting his review says that instead. No sales pressure: just how your plumbing actually works.

Plumbing permits & jurisdiction
Which office handles a plumbing permit in each Tri-Cities city, the West Pasco area, and unincorporated county land — with primary government sources. Useful before a water heater or PRV replacement, because the right office depends on the property, not the mailing name.
Hard water
How local water conditions can affect water heaters, faucets, and fixtures across the Tri-Cities. It shows where each utility publishes its numbers, so a scale decision rests on your water rather than a neighbor’s.
Water heater maintenance
How sediment, heater age, water conditions, and maintenance history affect tank-water-heater care. Read it before flushing an older tank, since age and a questionable drain valve change what is safe to do.
What size water heater
Why gallons is the least useful number, what a first-hour rating actually tells you, and why a 40-gallon gas unit can out-deliver a 50-gallon electric. Also the faults that imitate an undersized heater.
Water heater leaking
Where water under a heater actually comes from, which leaks are repairable and which are not, and the first steps to take before a plumber arrives. The drain valve, the relief line and the tank body look the same on the floor and mean very different things.
How long water heaters last
What actually sets a tank's lifespan — the anode rod, water conditions and sediment — and the signals that a heater is finishing. Also why the warranty term is a manufacturing guarantee, not a prediction about your water.
Expansion tanks
What thermal expansion is, why a closed system has nowhere to put it, and how to tell whether your expansion tank has already failed. A dripping relief valve is usually this, not a faulty valve.
Backed up right now?
How to tell a main line backup from one clogged drain, what to stop doing immediately, and why chemical drain cleaner makes the job worse and more hazardous.
Frozen pipes
Practical steps to protect outdoor faucets and exposed pipes before freezing weather—and what to do if a pipe freezes. A freeze split often shows up only when the hose bibb is first used in spring, so fall prep is the cheap part.
Water pressure & PRVs
What a PRV does, signs of excessive water pressure, and why pressure above about 80 psi deserves attention. Excess pressure stresses valves, supplies, and water heaters quietly, which is why a gauge reading comes first.
Galvanized pipe
How to recognize galvanized steel water lines, common aging problems, and practical repair considerations. It helps owners of older homes tell a one-spot repair from a wider piping condition before deciding.
Main-line warning signs
Warning signs that may point to a main-line problem, including gurgling, multi-fixture slowdowns, and low-drain backups. Recognizing the pattern early can mean a scheduled cleaning instead of sewage at the lowest drain.
Clogged plumbing vent
Gurgling drains, slow fixtures and a toilet that loses water can point to a blocked vent rather than a clogged drain. How to tell the two apart, and what not to do on the roof.
Water heater brands we install
Bradford White and A.O. Smith tank units and Navien tankless: why Sonlight installs these brands, what matters more than the brand, and service for any brand.
Water around the toilet base
Water on the floor around a toilet usually comes from the seal under it, the supply line, the tank-to-bowl seal or condensation. How to find which one, and what to do now.
Garbage disposal care
Everyday use, what to keep out of it, how to clean it, and what to do when it hums, stops or leaks — with the power off first.
Water softener overflowing
A brine tank that overfills usually points to the drain line, injector, control valve or float. What to check, what to do right now, and when to call a plumber.
Gas vs. electric
How gas and electric tank water heaters differ in recovery, operating costs, venting, and installation needs. Worth reading before a replacement, because switching fuel types changes the installation, not just the heater.
Customer-supplied fixtures
What to check before buying your own faucet, toilet, or disposal: compatibility, missing parts, warranty, and fit. Checking fit before you buy avoids a second trip to the store once the old fixture is already out.
Emergency shutoff
Where a home’s main water shutoff may be, how common valve types close, and when not to force a stuck valve. Knowing where the valve is before anything leaks makes a burst supply line far easier to control.
