Cold showers, rusty water, a puddle around the tank, or a pilot that won't stay lit — when a water heater fails in an Anaheim single-family home, you need it handled today, not next week. Alliance is a family-owned plumbing company based in Fontana, focused on Los Angeles and Orange County homeowners who want the problem solved the first time. We install and repair tank, tankless, gas, and electric water heaters across Anaheim with accurate pricing upfront and same-day service on most calls.
What water heater installation and repair involves
Water heater work looks simple from the outside and rarely is. A repair starts with diagnosing the actual failure — a bad thermocouple, failed heating element, corroded anode rod, cracked dip tube, sediment-choked tank, faulty gas valve, tripped high-limit switch, or a leaking T&P relief valve all present in similar ways. We test the unit, check gas pressure or voltage, inspect the venting, and confirm whether repair is the right call or whether the tank is at end of life.
Installation involves sizing the unit to the household's actual hot water demand, matching fuel type, and bringing the install up to current California plumbing code. That means proper seismic strapping (double-strapped, upper and lower third of the tank), a drip pan with a drain line where required, an expansion tank on closed systems, code-compliant venting for gas units, sediment traps on the gas line, and a T&P discharge line routed correctly. For tankless, we handle gas line upsizing, condensate drainage, and dedicated venting. We haul the old unit away and leave the space cleaner than we found it.

Our water heater installation and repair process
- Call or book online. Tell us the symptoms, the tank size and fuel type if you know it, and your Anaheim address. We schedule same-day when the calendar allows.
- On-site diagnosis. A technician inspects the unit, tests components, checks the venting, gas supply or electrical feed, and identifies the real cause.
- Upfront quote. You get a written price for the repair or, if replacement makes more sense, options for tank and tankless units sized to your home.
- Approval and parts. Once you approve, we pull common parts from the truck or source the new unit the same day when possible.
- Installation or repair. Old unit drained and removed, new unit set, strapped, connected, vented, and tested. Gas leak-checked with a manometer; electric units meggered where appropriate.
- Walkthrough. We show you the shutoffs, the T&P valve, the recirculation controls if equipped, and how to flush the tank annually.
- Haul-away and cleanup. Old tank goes with us. Permit paperwork handled where required.
What water heater installation and repair typically costs
A minor repair — thermocouple, igniter, heating element, T&P valve — sits at the low end. A full standard 40 or 50-gallon gas tank replacement runs higher because of the unit itself, code upgrades, and disposal. Tankless conversions cost the most because they usually involve gas line upsizing, new venting, and electrical work. Estimates range based on tank size, fuel type, whether it's a straight swap or a conversion, condition of the existing gas or water lines, expansion tank requirements, and whether the install location needs a drain pan or seismic upgrades.
We quote flat, itemized pricing before we start — not an hourly meter. Ask about the $79 service special on tanks up to 50 gallons and the $150 tankless flush. New installation estimates are free. Call for your upfront quote.

Frequently asked questions
How long does a water heater replacement take in Anaheim?
A like-for-like tank swap typically takes 2–4 hours on-site. A tankless conversion is a longer job — often most of a day — because of venting, gas, and mounting work.
Should I repair or replace my water heater?
If the tank itself is leaking, replacement is the answer — the steel liner has failed. If the failure is a component (thermocouple, element, valve, anode) and the tank is under about 8 years old, repair is usually the smart call. We'll tell you honestly which one fits your unit.
Do you install tankless water heaters?
Yes. We size the unit to your fixture count and simultaneous hot water demand, upsize the gas line if needed, and handle venting and condensate. We also service and flush existing tankless units for $150.
Do you offer same-day water heater service?
Yes, same-day service is available on most Anaheim water heater calls, and our emergency line runs 24/7 for active leaks and no-hot-water situations.
Is there a service fee?
Yes, a service fee applies for the diagnostic visit on repair calls. New installation estimates are free. You'll know the full price before we start any work.
Do you offer discounts?
Yes — Senior and Veteran discounts run year-round, plus current promotions include $79 water heater service on tanks up to 50 gallons and $150 tankless flush and service.
