If you know what a careful replacement includes, you can compare estimates on what's actually being done instead of on a single number. Two quotes can look very different because one includes venting updates, strapping and a permit and the other doesn't.
In Orange, many replacements are in garages of mid-century homes, where an older heater may have been installed before current requirements and may have been patched more than once. The new installation is the chance to correct those things.
A typical replacement, start to finish
Order and details vary by home and heater.
- Before the visit
- The plumber confirms the type, size and fuel, checks access, and says whether a permit will be pulled.
- Shutdown
- Gas or power is turned off, the cold supply is closed and the old tank is drained.
- Removal
- The old heater is disconnected and hauled away, and the area is checked for water damage.
- Setting
- The new heater is positioned, on a stand or pan if required, with proper clearances.
- Connections
- Water lines, a gas connector or electrical circuit, and venting are connected to suit the new unit.
- Safety items
- Seismic straps, the T&P relief valve and its discharge line, and any expansion control are installed.
- Start-up
- The tank is filled and purged of air, then lit or powered and checked for leaks and correct draft.
- Inspection
- If a permit was pulled, a city inspection follows. Check with the City of Orange on its process.
A written estimate should spell out
- The heater's model, type, fuel and capacity or flow rate
- Removal and disposal of the old unit
- Water connections and shutoff valve condition
- Gas connector or electrical work
- Venting work, if any
- Seismic strapping
- Relief valve and discharge line
- Permit, if one is required, and who obtains it
- The total price and what would change it
What makes one replacement bigger than another
| Factor | Why it matters |
|---|---|
| Changing type (tank to tankless) | Usually means new gas sizing, venting and mounting |
| Changing fuel (gas to electric or heat pump) | May need a new electrical circuit |
| Hard-to-reach location | Attics and tight closets take more labor |
| Outdated venting or strapping | Bringing them up to current requirements adds work |
| Damaged shutoffs or connectors | Worn valves are often replaced at the same time |
Ask before you sign
- Will you pull a permit if the city requires one?
- Does the price include strapping, venting and the relief valve line?
- What happens if you find a problem, like a bad shutoff valve, once you start?
- How will you dispose of the old heater?
- What maintenance does this new unit need with our water?
Common questions
Does a water heater replacement need a permit in Orange?
Permit requirements are set by the city. Check with the City of Orange's building department, and ask your plumber whether they will obtain any required permit.
Can a replacement be done the same day?
It depends on the plumber's availability, whether the heater is in stock and how much else has to change. Ask the contractor directly.
Should I replace the shutoff valve too?
If it's old, stiff or leaking, replacing it during the job is common and easier than doing it later.
