Planned or prompted by a failure

Water heater replacement and installation

Whether you choose a tank, tankless, hybrid or Marathon heater, every Trident Plumbing & Drain installation covers the same ground: selecting the system, taking out the old unit, fitting the new one and testing it. What changes is how much time you have to decide.

Our North Phoenix office coordinates Chandler service. If the heater has a fault that has not been assessed, the Chandler water heater repair page covers diagnosis. The sections below deal with replacing it.

Ahead of a breakdown

Planning a replacement before the heater fails

A string of repairs, a supply that can no longer cover normal use and visible deterioration all justify an inspection with replacement on the agenda. The findings show whether the problem can be repaired or whether a new heater makes more sense.

While the heater still works, there is room to compare tank, tankless, hybrid and Marathon options, review the installation each one needs and agree on the scope before the work is scheduled.

After a failure

When the old heater has already failed

A heater that is leaking or has stopped producing hot water needs its cause assessed before a replacement is chosen. Tell the office whether water is still escaping, where it is collecting and which fixtures have lost hot water.

If replacement is recommended, the same steps apply: agree on the system, remove the old unit, then install and test the new one. Ask what supports the recommendation so the choice is still a considered one.

Water conditions

Consider hard water in the plan

Hardness minerals can contribute to scale in water heaters as well as on fixtures. When a heater is being replaced, mention any scale or residue you see around the home so water conditions are part of the conversation about the new equipment.

A water softener can be discussed alongside the new heater if hardness is a concern. Softening reduces those minerals, though the new heater still needs the maintenance its model calls for.

After installation

Set up care for the new heater

Trident's Preventative Maintenance membership covers regular care for the water heater and household plumbing, including a water heater flush and a whole-home plumbing inspection. Ask whether it suits the heater you choose.

Report leaks, temperature changes or new noises as they appear instead of saving them for a routine visit. Routine care and fault repair are separate, so a developing problem should be looked at on its own.

What changes

Like for like or a new setup?

The City of Chandler's homeowner permit manual lists like-for-like replacement of a residential water heater among the work that needs no building permit. A change is a different matter. Switching from electric to gas, moving the heater or running a new gas line to a tankless unit involves piping the manual leaves out of exempt ordinary repairs, and its gas permit section asks for a riser schematic, appliance BTU ratings and line sizes. If a plan sits in between, ask the City's Plan Reviewer of the Day.

The new heater will also be heating hard water. The City's 2025 water quality report lists hardness from 10.1 to 16.8 grains per gallon, and its FAQ notes that most manufacturers suggest a flush every six months in homes without a softener. Install with that schedule in mind: a tank's drain valve should be easy to reach, and isolation valves on a tankless unit make descaling a routine visit. A softener upstream reduces the buildup.

Installation quotes

Fuel, type and location drive the install price

An installation quote reflects the unit you pick and everything it takes to connect it. Compare these factors before you compare totals.

GreenSky® financing is an option for a new heater, and our preventative maintenance membership covers a yearly flush once the new heater is in.

  • Tank, tankless or hybrid, and the size your household needs.
  • A like-for-like swap, or a change of fuel, type or location.
  • Gas piping, venting, electrical or drain work the new unit requires.
  • Any City permit and inspection the change calls for.
  • Hauling away the old heater.

Permits and water for a new heater

Whether an installation needs a City permit depends on what changes. The water it will heat matters too.

Our 12 year old water heater was leaking. I called and spoke with Shelby who was able to dispatch a technician immediately, same day… Tyler arrived on time, worked efficiently and cleaned up after himself.

Questions about water heater installation in Chandler? Start here, or tell us what is happening at your home.

Ask our team
Is it worth replacing a heater that still works?

It can be, depending on its condition, repair history and whether it keeps up with demand. An inspection shows where the heater stands, and planning ahead leaves time to compare options.

What should I do if the heater is leaking right now?

Contact the office and say whether water is still escaping and where it is collecting. The cause is assessed first, then repair or replacement is discussed.

Should hard water affect the choice of a new heater?

Mention it. Hardness can contribute to scale in water heaters, so water conditions belong in the discussion, and a softener can be planned alongside the heater if hardness is a concern.

Is there a maintenance plan for the new heater?

Trident's Preventative Maintenance membership includes a water heater flush and a whole-home plumbing inspection. Ask whether it fits the heater you install.

Does switching to a tankless heater change the permit picture?

It can. The City's permit manual exempts like-for-like water heater replacement. A switch that adds or changes gas, water or vent piping falls outside the ordinary repairs that need no permit, so check with the City's Plan Reviewer of the Day before work starts.

What does the City ask for when a new heater needs a gas line?

The homeowner permit manual's gas section covers adding a gas line inside the house or connecting to an existing gas stub-out. It asks for a gas riser schematic showing each section of line from the gas meter, the total BTU rating of each appliance and each line's size and type.
