Frequently Asked Questions

Frequently Asked Plumbing Questions

Expert answers from Victor and the T-12 team

Can a tankless water heater handle sub-zero Montana winters?

Yes. We size Navien and Rinnai condensing units specifically for Montana's cold incoming groundwater (which drops to 38°F in January). We calculate the necessary BTU input and temperature rise so your showers stay steaming hot all winter.

Do I need to upgrade my gas line for a tankless water heater?

In many cases, tankless units require a 3/4-inch gas supply line due to higher instantaneous BTU demand (180,000 to 199,000 BTUs). T-12 Plumbing verifies your gas manifold and handles all gas line sizing safely.

How often does a tankless water heater need descaling in Billings?

Due to Billings' high mineral content, tankless units should be flushed annually with a food-grade descaling solution or vinegar. We install service isolation valves on every install to make this simple.
