Expansion Tanks, Permits and Code for a New Heater
Heating water makes it expand. In a closed plumbing system that extra volume has nowhere to go, so pressure climbs and the relief valve can start to drip. An expansion tank is a small pressurized vessel on the cold line that absorbs the change. Ask the installer whether your system is closed and whether a tank is needed.
Code also covers the venting of a gas unit, the relief valve discharge pipe and the shutoff valves. The plumber follows the code that applies at your address.
Maricopa County, which covers unincorporated Sun Lakes, says a like-for-like replacement needs no permit if the work follows manufacturer specifications. Relocating the unit or running new gas pipe is treated differently.
Parts of the area touch Chandler and Pinal County, so confirm your jurisdiction.
A new gas appliance connection or a longer gas run is covered on the gas line repair.
Tip: ask the installer to write down the heater size, model and install date so you have a record.

Tank Past Repair? What a New Installation Involves
When a tank leaks from the body, or repairs would cost more than they are worth, installation follows. The work is usually done in a few steps, and each one is worth asking about.

- The plumber confirms the fuel, the tank size, the vent path and the space around the unit.
- Power or gas is shut off, the cold valve is closed and the old tank is drained.
- The old unit is disconnected and removed, then the new tank is set on a pan or pad with fresh connectors.
- Venting, the relief valve and the expansion tank, where needed, are connected and checked.
- Water is restored, the tank is filled and the plumber checks for leaks, flame or element function and temperature.
Ask what comes with the job: new flexible connectors, a new relief valve and disposal of the old tank. Leaving those out can mean a second visit.

The simplest swap keeps the same fuel and size. Changing fuel means new venting, a new gas line or a new electrical circuit, so it is a larger job.
| Type | How it heats | Things to weigh |
|---|---|---|
| Gas tank | A burner under the tank | Needs a vent and a gas supply |
| Electric tank | Two heating elements inside the tank | Needs a suitable circuit and breaker |
| Hybrid or heat pump | A heat pump on top moves heat into the water | Needs space, airflow and a drain for condensate |
| Point-of-use or under-sink | A small unit near one fixture | Good for one sink, not a whole house |
Size is stated in gallons and follows how many people use hot water at the same time. A plumber can match a tank to your household instead of copying the old one. The tankless water heater page covers the option that removes the tank altogether.
Sun Lakes Water Heater Replacement: Like for Like or a Change?
Most replacements fall into one of three paths. Knowing which you want makes the quote conversation shorter.
Same fuel, same size
The quickest path. Connections and venting are already in place, and the work follows the old unit.
Larger or smaller tank
Worth asking about if the household changed. A different size may need different clearances or piping.
A different type
Moving to hybrid or tankless means added work: power, a drain, venting or a larger gas line. Ask what it adds.
Choosing a Plumber for the Installation
A water heater install touches gas, water and venting, so the plumber matters. Work for hire in Arizona is done by contractors licensed through the Arizona Registrar of Contractors, and you can ask any plumber to confirm their license before work starts.
Questions worth asking:
- Who will do the work, and are they licensed and insured?
- Is a permit needed for this job, and who handles it?
- What does the quote include: parts, haul-away and testing?
- What does the plumber check after the tank is filled?

Compare Your Options With a Plumber

☎ (480) 806-2944What to Have Ready Before the Installer Arrives
A smooth replacement starts with a little preparation. Clear a path to the heater and keep pets away from the work area. Note the fuel type, the tank size printed on the label and the approximate age of the unit, since the installer will ask for all three.

Take a photo of the label and of the pipes above the tank. Those two pictures tell a plumber more than a long description, and they help with planning the parts needed on the first trip.
- Whether the heater is gas or electric
- The size listed on the rating label
- Where the drain and relief valve pipes run
- Any water stains on the floor or ceiling below
- How many people use hot water each day
Ask the installer to explain what will be replaced beyond the tank itself. Flexible connectors, shutoff valves and venting parts are often renewed at the same time, because old fittings tend to fail soon after a new tank goes in.
After the New Heater Is In: Checks Worth Asking For
A finished job should end with the heater filled, vented where needed and tested. Watch for leaks at the connections over the first day, and confirm the temperature setting suits your household.

Ask where the shutoff valve for the water supply sits and where the gas valve or breaker is. Knowing both means you can stop a problem quickly later. Keep the paperwork with the model number for any maker claim.
Water Heater Installation Questions
Should I choose gas, electric, hybrid or a heat pump unit?
A homeowner replaces a failed gas tank and wonders if electric would be simpler. It can be, but the home needs the right circuit and the old gas line and vent become unused. Gas replacing gas keeps the work small. Hybrid and heat pump units need room and airflow. Ask the plumber to price each path.
What should I do if the old water heater floods the floor?
- Shut the cold supply valve above the tank.
- Switch the circuit breaker off, or turn the gas control to its off position.
- Move belongings out of the water.
- Call dispatch, and see the water damage page if the floor or walls are wet.
Do I need a plumber to install a water heater?
If the tank is leaking or the water is cold, yes. Installation involves gas or high-voltage power, venting and a pressure relief valve, so it is not a do-it-yourself job for most homes.
How do I choose between two sizes for my household?
Two options: match the old tank, or move up one size. Matching works if nothing changed. Moving up helps when more people share hot water, but needs space and sometimes new connections. Describe your household to the plumber and ask for both choices.
Can a leaking electric water heater be replaced the same day?
Often it can be, when a plumber is available and the tank is standard. Dispatch will tell you what is possible when you call, without promising a time.

If the unit can still be saved, see heater repair page. Thinking of a tankless model? Read tankless water heaters. A softener changes how scale builds up in a tank, which is covered under water softener work.
