Water Heater Replacement in Los Gatos: What to Expect, Start to Finish

Replacing a water heater is a job most homeowners deal with once a decade at most — which means almost nobody remembers how it works or what a good installation looks like. Here is the whole process, start to finish, the way we have been doing it for Los Gatos families since 1988.

If Your Water Heater Is Leaking Right Now

Water pooling around the base of the tank usually means it has corroded through from the inside, and that only goes one direction. Find the cold-water shut-off valve on the pipe above the heater and turn it clockwise until it stops. If you ever smell gas, close the gas valve and step outside before making any calls. Then phone us at (408) 358-6446 — we answer 24/7, and a leaking water heater is exactly the kind of call we build same-day room for.

What Replacement Day Actually Looks Like

Our plumbers arrive with drop cloths and shoe covers — read our reviews and you will see how often customers mention the cleanup. We shut off the water and gas, drain the old tank, and haul it away for recycling. The new heater goes in with a drain pan, new supply connectors, seismic straps to California code, and a relief line terminated where code requires. Every gas connection is leak-tested before the burner is relit, and we do not leave until you have watched hot water run at your own fixtures. A straightforward tank swap is almost always finished the same day.

Tank or Tankless: Decide Before the Old One Fails

The worst time to weigh your options is standing in a garage next to a puddle. If your current heater is eight years old or more, it is worth thinking ahead now. A like-for-like tank water heater replacement is the fastest path back to hot water. A tankless water heater ends the running-out-of-hot-water problem entirely and frees up floor space, though many Los Gatos homes need a gas line or venting upgrade to support one — work we handle ourselves rather than subcontracting out.

Two Local Wrinkles: Older Homes and Hard Water

A large share of Los Gatos housing predates modern plumbing standards, so replacements here often involve updating venting, shut-off valves, or drainage along the way — details we bring up to current code as part of doing the job right. And South Bay hard water works against your water heater at both ends: sediment blankets the burner in a tank unit, and scale clogs the heat exchanger in a tankless one. An annual flush is the single best habit for either type, and we can put yours on a schedule so you never have to think about it.

Choosing Who Does the Work

Whoever you hire, check two things: an active California contractor license (ours is #943556) and recent reviews from your own neighborhood. Simply Green Plumbing is family-owned, has served Los Gatos since 1988, holds a 4.9-star rating across 80+ Google reviews, and answers the phone 24/7.
