Tankless Units in Roanoke Homes
Most Roanoke homes keep the tankless in the basement or a utility room, with the vent through the side wall. Winter cold snaps and condensate drains cause the usual trouble.
What we run into in Roanoke
- Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.

Drip from the cabinet
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.

LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
