Tankless Water Heater Service in Leander, TX
Installation, repair, replacement, maintenance and descaling for tankless water heaters in Leander, TX and the surrounding neighborhoods.
Leander has grown faster than almost anywhere in the country over the last decade, and the housing shows it: Crystal Falls, Travisso, Bryson, Larkspur and Palmera Ridge are largely 2015-onward, and a good share of those homes came with a tankless water heater from the builder.
So our work here skews differently. Less converting, more maintaining — annual service and descaling on units that are five to ten years old and have never been flushed, plus repair calls on builder-grade units that were installed to the minimum spec.
What matters in Leander specifically
- Water: Leander is supplied through the Brushy Creek Regional Utility Authority from Lake Travis, similar in hardness to Cedar Park. Hard enough that a five-year-old unflushed builder unit is usually carrying visible scale.
- Permits: the City of Leander requires a permit and inspection for water heater replacement. We pull it.
- Housing: builder installs are legal and usually adequate, but they are specified to price. The two things we most often add afterwards are isolation valves — without which the unit cannot be flushed — and a properly routed condensate neutralizer.

My builder installed the tankless unit four years ago. Does it need anything?
Almost certainly a descale, and a check for isolation valves. If the builder left them off, fitting them now makes every future service straightforward and keeps the warranty maintainable.
Is the builder's warranty still good if you service it?
Yes. Manufacturer warranties require annual service by a licensed plumber, not by the original installer. We give you the written record they ask for.
Do you cover Liberty Hill and the 1431 corridor?
