Before We Leave

We Don’t Just Install It — We Prove It’s Safe

A water heater ties into your gas line, your venting, and your plumbing. Before we call a job done, we test all three — with electronic meters, not guesswork. Every install, every time.

🔥
Carbon Monoxide Test
We meter combustion and draft to confirm your unit is venting safely — and not putting carbon monoxide into your home.
💨
Gas Leak Test
Every gas connection we make is checked with an electronic gas detector before we leave — no soap-bubble guesswork.
💧
Water Leak Test
We pressure-check our connections and fittings so you don’t find a puddle under the tank next week.

Most companies eyeball it. We measure it — with meters — before we leave.

The Lifetime Guarantee

Most Cover Their Labor for a Year. We Cover Ours for Life.

When we install your water heater, we stand behind every connection, fitting, and hour of labor for as long as that unit is in service. If our workmanship ever fails under normal use, we come back and fix it — free.

The water heater itself is covered by the manufacturer’s warranty (typically 6–12 years). Our guarantee covers the part most companies walk away from after twelve months: the work.

What the Lifetime Guarantee covers →
Covered for the life of your unit:
✔  Water & gas connections we installed
✔  Fittings and joints made by our technicians
✔  Venting and flue work we performed
✔  Seismic strapping and mounting
✔  The installation labor itself
The unit and its internal components are covered by the manufacturer’s warranty. If you ever have a manufacturer claim, we’ll help you handle it.

Honest Pricing

You’ll Know Your Full Price Before We Start

Most plumbers won’t tell you the price until they’re standing in your garage. We give you a free, flat-rate quote upfront — because that’s how we’d want to be treated.

Free Upfront Flat-Rate Quote
Every standard tank installation includes:
✔  Professional-grade tank water heater unit
✔  Full installation by a licensed plumber
✔  Removal & disposal of your old unit
✔  All labor and standard fittings
✔  Same-day service on tank installs
✔  Lifetime guarantee on our workmanship
Your price depends on your tank size, fuel type, and any code-required items specific to your home. We walk through everything before we start — nothing gets added to your invoice without your go-ahead.

Why Happy Water Heaters

We’re Not a General Plumber.
We’re Specialists.

There’s a big difference between a plumber who does water heaters and a company built exclusively around them. Here’s what that difference means for you.

🎯
Water Heaters Only
We don’t fix leaky faucets, clear drains, or install toilets. Every hour of every day is dedicated to water heater replacement. That focus makes us faster, better stocked, and more experienced than any general plumber.
📋
Nothing Added Without Your Approval
Every item on your invoice is explained and priced before we do anything. We don’t discover problems mid-job and spring costs on you. If something unexpected comes up, we stop and talk to you first.
🏅
Guarantees That Mean Something
Same-day or the labor’s free. Workmanship guaranteed for the life of your unit. We structured our entire operation — inventory, scheduling, staffing — around keeping both promises every single time.
🏡
Local & Accountable
We live and work on the Central Coast, backed by Central Plumbing Inc. and 20+ years in the trade. When you leave a review — good or bad — it matters to us personally.

Common Questions

Frequently Asked Questions

What does “same day or it’s free” actually mean?
If you call before noon and we don’t complete your tank water heater installation the same day, we waive the installation labor entirely. You pay for the unit but not the labor.
Why don’t you post a price?
Every home is different — tank size, fuel type, location, and code requirements all affect the job. Rather than post a teaser number that changes once we see your setup, we give you a free, flat-rate quote upfront. You’ll know your full price before we start, and nothing is added without your approval.
What are code-required items?
California code requires items like seismic straps, expansion tanks, and updated valves on most installations. These are always quoted as separate line items and approved by you before we proceed.
Do you install tankless water heaters?
Yes. Tankless installations are more complex and priced individually — the same-day guarantee doesn’t apply to tankless, but the Lifetime Workmanship Guarantee covers both, and we quote everything upfront.
What does the Lifetime Guarantee cover?
Our workmanship — the connections, fittings, venting, and labor we performed — for the life of your water heater. The unit itself is covered by the manufacturer’s warranty, typically 6–12 years. If our work ever fails under normal use, we fix it free.
Do I need to maintain my unit to keep the guarantee?
Yes — keeping your unit maintained per the manufacturer’s recommendations keeps the workmanship guarantee valid. Central Coast water is hard on water heaters, so annual maintenance protects both your unit and your coverage.
Do you haul away the old water heater?
Always. Removal and disposal of your old unit is included in every installation — no extra fee, no leaving it in your driveway.
What if I call after noon?
We’ll still do everything we can to help you the same day. The free-if-late guarantee requires a before-noon call, but we never turn down a job without trying first.
