Water heater installation and repair

Chapter 01
The Signs a Water Heater Is Done
A water heater does not usually just stop. It leaks first, a slow ring of rust and water around the base or a wet spot on the pan underneath, and by the time you can see it, the tank itself has already started to go. Other times it is quieter: the pilot will not stay lit, the burner cycles on and off without reason, or the unit rumbles and pops when it heats, which usually means sediment has been building up on the bottom of the tank for years without anyone noticing. A gas smell near the unit or a breaker that keeps tripping on an electric model is worth calling about the same day, not waiting out.
The most common call is simpler than any of that. The hot water runs out faster than it used to, or the shower starts cold halfway through and nobody in the house changed their habits. In Maple Valley and the towns around it, that is often a tank quietly losing capacity as sediment settles in, not a sign anything was done wrong. It is a sign the unit is getting old and worth a look before it fails on its own schedule instead of yours, usually on a weekend or the day before guests arrive. A household that has added people, a second bathroom, or a new appliance since the water heater went in can also simply outgrow it, which looks the same as a failing unit but has a different fix.

Tank or Tankless, You Pick
Cahill's installs both. A Rinnai tankless unit went in for one Maple Valley customer, mounted flush in a utility closet with the gas and water lines run clean and tight, no tank taking up floor space at all. Down the road, a Bradford White gas tank unit went in on a proper stand in a garage, the kind of straightforward swap most homes still call for. Both jobs are real installs, not stock photography, and both were finished the same way: connected correctly, tested, and left clean, with the old unit hauled away rather than left for the homeowner to deal with.
That customer with the Rinnai left a five star review afterward and singled out one thing: Cahill's did not push a model on him the way he expected from other companies. He picked what he wanted installed. That is the standard on every water heater job, tank or tankless, gas or electric: the house tells you what will fit and what the household actually uses, and the homeowner decides from there, not the other way around. A family running two showers back to back at seven in the morning needs a different answer than a couple who mostly use hot water in the evening, and that conversation happens before any unit gets ordered.
Chapter 03
After the Water's Back On
One customer needed a water heater replaced for a tenant while he was out of town, and it had to happen fast. Cahill's had it done quickly, with no surprises and no extra charges added on afterward, exactly what he needed from a job he could not be there to watch himself. He called the work thorough and high quality, done in a timely manner without anything sprung on him at the end.
That is the part that matters once the new unit is in: what happens after. Tank units do better with an occasional flush to clear sediment before it builds back up, and the anode rod inside is worth checking down the road rather than ignored until the tank starts to go again. Tankless units need periodic descaling, more so where the water runs harder, and the discharge line and venting should stay clear and unobstructed year round. None of that is complicated, it just tends to get forgotten until the unit starts acting up again.
Keep whatever paperwork came with the install. It is the easiest thing to lose and the first thing you will want if a question about the unit ever comes up later. Beyond that, a water heater that was installed right and picked to fit the house, rather than pushed on the homeowner, should not need attention again for a long while, which is the whole point of doing it this way. Any plumbing turned off to swap the unit, at the shutoff or at the meter, should be back on and checked for drips before the crew leaves the driveway.
Two real installs like this one: a Rinnai tankless and a Bradford White gas tank, both picked by the homeowner, not by Cahill's. Licensed, bonded and insured. Call (425) 432-1977.
