Tank to Tankless Conversions in Menifee, CA
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units usually need a larger gas line, often three quarter inch or bigger, plus new venting. We evaluate your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Expect a conversion to take a full day.

Condensing Tankless Replacement in Menifee
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by capturing heat from exhaust gases. They vent through low-cost PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. A warm, dry climate is the main factor for plumbing in Southern California, with long irrigation seasons and steady demand on outdoor lines. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth the price.
Exterior Mount Tankless Units in Menifee, CA
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. Freezing pipes are rare in most of Southern California, and many homes have exposed outdoor plumbing that would never pass in a colder climate. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Navien Tankless Water Heater Replacement in Menifee, CA
Navien tankless water heaters are popular for their condensing technology, delivering high efficiency and performance. When it is time for a Navien tankless water heater replacement in Menifee, CA, you can count on FKM Plumbing. We have broad experience with Navien's advanced systems, including their combination boiler and water heater units. Our installation process focuses on dialing in your new Navien's performance, so you benefit from its energy-saving features and reliable hot water output.
Gas Tankless Water Heater Replacement in Menifee
Many homes in Menifee rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes thorough inspection of your existing gas lines, proper sizing of new gas lines if needed, and secure venting to the outdoors. We put a priority on safety. All gas connections and combustion air requirements meet Southern California and local codes, heading off potential hazards and maximizing efficiency.
Recirculation Tankless Upgrades in Menifee, CA
If you are tired of running the tap waiting for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use in check while saving thousands of gallons of wasted water a year. This upgrade is popular in long single-story ranch homes.

Businesses in Menifee, CA often require robust hot water solutions, and tankless systems can provide the efficiency and capacity needed. We regularly replace commercial tankless units for restaurants, offices and other facilities with minimal disruption to your operations.
