Bigger is not better, and the swap is not just the tank
Many people assume a bigger tank is a safer choice, or that a replacement is a simple lift-out. Neither is quite true. An oversized tank costs more to heat and takes more room. An undersized one runs out in the middle of a shower. The right size follows how many people use hot water and when.
A replacement also touches more than the tank. The cold supply, the shutoff valve, the flexible connectors, the relief valve and its drain pipe, and on gas units the vent and gas connection all get checked. Old parts are usually replaced at the same time, since changing them while the tank is out saves a second visit.
Signs the heater is due for replacement
- Water seeping from the steel shell, not from a fitting.
- A tank that is well past ten years old and needing repeated repairs.
- Rust-colored hot water that does not clear.
- Rumbling and popping that a flush no longer fixes.
- Hot water that runs out far sooner than it used to.
Gas unit? A new gas heater must vent exhaust outdoors. Never block a flue, and install carbon monoxide alarms near sleeping areas. If the room smells like gas, step outside before you phone anyone.
Hot water heater installation: what the visit covers
The visit starts with the old unit. The plumber shuts off the water and the fuel, drains the tank and disconnects it. Then the new heater is set on a stand or pan where the code and the layout call for one, connected to the water lines and tested.
On a gas heater the plumber connects the gas line, checks it for leaks and confirms the vent draws properly. On an electric one the power is connected and the elements are checked. Either way, the relief valve gets a discharge pipe run to a safe spot, and the water is purged of air before the tank is switched on.
Ask for a short walkthrough at the end. You should know where the shutoff valve is, how to set the temperature and how to drain the tank later. Keep the paperwork and the model and serial number, because the warranty depends on them.
Gas water heater replacement in Wittmann: like for like or a change?
The simplest replacement keeps the same fuel, size and location. It is the fastest, and it reuses the existing connections. A change of fuel or type is a bigger job: gas to electric needs a circuit, electric to gas needs a gas line and a vent.
| Type | How it heats | Good fit | Watch for |
|---|---|---|---|
| Gas tank | A burner under the tank | Homes already piped for gas | Needs a proper vent and a gas connection |
| Electric tank | Two heating elements | Homes with no gas service | Needs a dedicated circuit of the right size |
| Hybrid (heat pump) | A heat pump on top of an electric tank | Homes with space and a warm room | Needs clearance and a drain for condensate |
| Point-of-use | A small electric unit near one sink | A far-off tap that waits for hot water | Supplies one fixture, not the house |
Whether your home has natural gas service or uses propane is something to confirm from your bills before choosing. Do not assume. If the change needs a bigger gas pipe or a new connector, see gas line work. Thinking about on-demand heating? The tankless water heater page covers venting, gas supply and descaling in detail.

Say gas or electric, and how big the tank is.
Expansion tank, permit and code: ask before the old tank comes out
Code items turn up on most replacements. A thermal expansion tank absorbs the pressure that builds when water heats in a closed system. Some homes need one, and a plumber can test your pressure to see. A relief valve with a proper discharge pipe is required.
Permits raise their own question. Wittmann has no town government of its own, so the county typically issues building permits. Whether a like-for-like swap needs one is for the county to say, and the plumber should know the answer for your address. Ask who files it and who is present for any inspection.
Hard water matters here too. Groundwater-supplied communities in Arizona often have hard water, and scale shortens a heater's life. The hardness number for Wittmann is not listed on this site. The water quality report from your provider gives it, and a softener can protect the new heater. The softener and filter page explains the options.
Choosing who installs it
Ask the questions that tell the work apart. Will the plumber who comes do the connection, or subcontract it? What parts are replaced along with the tank? Is the permit included? What does the warranty cover on the tank and on the labor, and who handles a claim?
A written scope helps. It should name the heater, the size, the fuel and the parts replaced, so you can compare two proposals on equal terms. Be wary of a quote that does not say what happens to the old tank or the vent.
Sizing is part of the conversation. Ask the plumber to explain why a size fits, and describe your busiest hot water morning to help. What a replacement costs depends on the type, size and any code work. The quote guide lists what raises or lowers a quote.

Five replacement questions, answered
Is a plumber needed to install a water heater?
Yes for almost every home. A water heater joins gas or high-amp electric service, water supply, a relief valve and, on gas units, a vent that carries exhaust outside. A mistake in any of them can mean a leak, a fire or carbon monoxide in the house. A plumber also knows what needs to be replaced along with the tank, such as old shutoff valves and flexible connectors, and whether a permit applies.
How long does it take to replace two water heaters?
Start with the permit question, because it can set the schedule. Wittmann sits outside any town limits, so the county typically issues building permits, and the plumber can say whether your address needs one and who files it. With that settled, two like-for-like tank replacements are a longer visit than one, mostly because each unit is drained, removed, set, connected and tested in turn. Say at the start if both heaters are down, so the plumber arrives with two tanks.
Who handles replacing a leaking electric water heater?
A plumber handles the water side and, in most cases, the connection to the circuit. Before the visit: 1. Switch off the heater's breaker. 2. Close the cold water valve above the tank. 3. Open a hot tap somewhere in the house so the tank stops pushing water out of the leak. 4. Put towels or a pan under the leak and photograph it. One caution: do not touch the wiring on top of the unit with wet hands or while standing in water.
When should I replace a water heater that flooded the floor?
Picture a tank that has split at the seam and sent water across a garage floor. Stop the water and power, then call. Once water comes out of the steel shell, replacement is the answer, because no fitting can fix a failed tank. A flooded floor also needs drying, so mention the extent of the water when you call. If the water has reached walls or flooring, the work in the water damage section of this site applies as well.
Is it better to install a tank or a tankless water heater?
What to do now: if the tank is leaking, replace it with the same type so hot water comes back quickly. What can wait: the switch to tankless, if you want one. That change usually involves a larger gas line, a new vent or higher electrical load, and it deserves a planned visit. Many homeowners get a tank now and plan a tankless upgrade for the next replacement. The tankless page covers what changes.
If the old heater might only need a repair
Not every failing heater needs to go. A bad element or a worn thermocouple is a part. See heater repair before you decide. If the tank has already flooded a room, the water extraction and drying page covers what comes next. Ask about the soonest visit, and read how dispatch works on the homepage.
