Smith, with same-day installation available for most gas tank replacements when booked before 2pm.
Our Installation Process

Same-Day Installation When Booked Before 2pm
Many water heater installations can be completed the same day when scheduled before 2pm, which matters when a household is without hot water. Our in-house crews carry common tank sizes and parts, so a straightforward swap often doesn’t require a second visit. Heat pump water heaters are the exception: the city permit comes first, so those installs are scheduled once it is approved.

From First Call to City Sign-Off
A gas tank replacement is a short job, and most of it happens in one visit. This is the order it runs in.
Call or request a quote
Tell us what is happening: no hot water, a leaking tank, or a unit near the end of its service life. Call before 2 PM and a technician arrives the same day.
On-site check
The technician looks at the existing unit, the gas line, the venting, and the space around it, then walks you through your options.
Upfront written price
You approve the price before work starts. It covers removing the old unit, the new water heater, labor, and the permit.
Permit
Replacing a water heater requires a plumbing permit. We pull it for you. Sunnyvale and San Jose both issue this permit online.
Installation
The old tank comes out and we haul it away. The new one is set, strapped, connected, and tested. A standard tank replacement takes 2 to 3 hours, and we register the manufacturer warranty before we leave.
City inspection
The city inspects the finished installation, and a JetPipe team member meets the inspector on site. Sunnyvale requires one final inspection once the work is complete.
What the City Inspector Checks
The inspection follows a set list, and we build every install to it.
Seismic straps
One in the top third of the tank and one in the bottom third.
Relief valve drain line
Runs to the outside of the house and points down, so a discharge never ends up in a crawl space.
Venting
Double-wall metal vent pipe with clearance from anything combustible, ending above the roof under a listed cap.
Sediment trap
Installed on the gas line just ahead of the water heater.
Combustion air
Enough air for the burner, whether the unit sits in a garage or in a closet.
Garage installs
Burner and controls sit at least 18 inches above the floor, unless the unit is rated flammable vapor ignition resistant.
This is Sunnyvale’s checklist for a water heater replacement. San Jose and other South Bay cities enforce the same California code with their own local details.
Financing through Synchrony with $0 down and 0% interest when you pay the full balance within 6, 9, 12, or 18 months. You pay exactly the amount on our invoice. Subject to credit approval.
Tankless and Heat Pump Installation
Homeowners who want continuous hot water or lower energy use often choose a tankless water heater or a heat pump water heater instead of a standard tank. Both require additional planning around gas line sizing, venting, or ambient air placement, which our licensed technicians handle as part of the installation.
Utility Rebates
Certain heat pump water heater installations qualify for utility rebates. We can help identify whether your household qualifies and assist with the paperwork as part of the installation process.

Removing Your Old Water Heater
Removing the old unit safely is part of every installation, not an afterthought. Our technicians disconnect the gas or electrical supply, drain and haul away the old tank, and check the surrounding area for any wear that should be addressed while everything is already accessible. Old units are disposed of responsibly, and we confirm the new water heater’s connections match current code before the job is finished.

Frequently Asked Questions
How long does a water heater installation take?
A standard tank replacement typically takes 2 to 3 hours. A tankless installation runs 3 to 5 hours depending on venting and gas line work required. Heat pump installations vary based on location and electrical needs.
Can you install the same day?
In most cases, yes, if you call before 2 PM. We stock the most common tank and tankless units. For less common sizes or models, we will confirm availability when you call. Heat pump water heaters need a city permit first, so those installs are scheduled after it is approved.
Do I need a permit for a water heater installation?
Yes. Sunnyvale and San Jose both require a plumbing permit to replace a water heater, and the city inspects the finished installation. We pull the permit as part of the job, and its cost is included in your flat-rate quote.
What brands do you install?
We work with Navien, Rheem, Bradford White, A.O. Smith, State, and other major brands.
Can you install a tankless water heater where my tank unit is now?
Usually yes, but a tankless unit requires a dedicated gas line upgrade and proper venting. We assess your existing setup before recommending or committing to a specific approach.
Do you haul away the old unit?
Yes. Removal and disposal of the old unit is included in every installation.
What rebates are available for heat pump water heaters?
Rebates apply when you switch from a gas water heater to a heat pump. Depending on your city, the program is WestLight Energy (formerly Peninsula Clean Energy) in San Mateo County, City of Palo Alto Utilities (CPAU), SVCE, or San Jose Clean Energy (SJCE). A gas tank or gas tankless replacement does not qualify. We confirm eligibility before the installation.
Is the installation guaranteed?
Yes. All labor is backed by our 1-year workmanship warranty. Manufacturer equipment warranties are registered by us before we leave.
Can I finance a new water heater?
Yes. We offer financing through Synchrony with $0 down and 0% interest when you pay the full balance within 6, 9, 12, or 18 months, so you pay exactly the amount on our invoice. You get the written price for the new water heater first, then decide how to pay. Subject to credit approval. See financing options.
