Tankless Water Heater Installation

Hot water on demand, lower energy bills, and no tank taking up space — Downs Plumbing installs it right the first time.

Tankless Water Heater Installation

More homeowners across Menifee and Southwest Riverside County are making the switch to tankless water heaters — and for good reason. A tankless system heats water only when you need it, which means you are not paying to keep a 40 or 50 gallon tank hot around the clock. For families in Temecula, Murrieta, and Canyon Lake who are tired of running out of hot water or watching their gas bill climb, a tankless unit is often the most practical upgrade they can make. Peter at Downs Plumbing has installed tankless systems throughout the valley and understands what it takes to do the job correctly.

Tankless water heater installation is not as simple as swapping out the old unit. It requires evaluating your existing gas line size, venting configuration, and water pressure to make sure the new system will perform the way it is designed to. A tankless unit installed without proper gas line sizing will underperform from day one. Downs Plumbing handles the full assessment and installation — from removing your old tank unit to sizing the gas supply, installing the new unit, venting it correctly, and testing it before leaving your home.

If you are considering going tankless in Menifee, Wildomar, Lake Elsinore, or anywhere in the surrounding area, call and Peter will walk you through whether your home is a good candidate and what the full installation involves. No pressure, no upselling — just an honest conversation about what makes sense for your home.

Why Choose Downs Plumbing for Tankless Water Heater Installation

  • Full Installation, Not Just the Unit Swap — Downs Plumbing handles every part of the installation — gas line work, venting, water connections, and testing. You are not getting someone who bolts the unit to the wall and leaves the rest for someone else to sort out later.

  • Gas Line Expertise — Proper tankless installation depends heavily on having the right gas supply. Peter is a licensed plumber with extensive gas line experience, which means the gas side of the installation gets the same attention as the water side. That combination is what separates a system that performs from one that disappoints.

  • Honest Pre-Installation Assessment — Not every home is immediately ready for a tankless upgrade. Peter will tell you upfront if your gas line needs upgrading, what the full cost looks like, and whether the investment makes sense for your situation. You will not get a surprise bill after the work starts.

  • 25 Years of Local Experience — Peter has installed tankless systems in homes across Menifee, Temecula, Murrieta, French Valley, and beyond. He knows the common configurations in this area and works efficiently because he has done this hundreds of times.
