Own Hydrotek Plumbing LLC? Claim this listing

Hydrotek Plumbing works in Spokane Valley and Spokane, handling residential plumbing with a lean toward water treatment. Alongside water heater installation, repair and replacement, the company advertises whole-home water filtration and water softener installs, plus leak detection and on-site assessments. Fixture work rounds it out: toilets, vanities, faucets. It's a small shop formed in 2024, with the owner doing the work and a crew the state puts at one to three people.

The state lists Andrew Starnino as a principal since 2024, the year Hydrotek Plumbing LLC was formed. The work is residential. Water heaters are the core of it, and the company advertises both repair and full replacement. The water treatment side, filtration and softeners, is less common as a headline service for a small plumber, and it pairs naturally with leak detection and assessments for a homeowner sizing up an older house or one they're about to buy. Hours run Monday through Friday, daytime only. That makes Hydrotek a fit for planned household jobs: swapping a tired water heater, adding a softener or filtration system, replacing a vanity and faucet, or getting a leak checked before closing on a house in the Valley. Commercial plumbing sits outside the service list, and a shop that keeps weekday hours suits scheduled work better than a Saturday night burst pipe. Plumbing demand in Spokane bunches up around the cold. The first hard freeze in late fall and the deep-winter cold snaps bring frozen lines and water heaters that give out under load, and small shops fill up fast then. Spring brings remodel fixture work and home-sale inspections. A water heater nearing the end of its life, a softener install or a bathroom fixture swap is easier to book in late summer or early fall, before the freeze, than in the middle of a January cold spell. A pre-purchase leak check should be lined up as soon as an offer is accepted.
