Tankless Units in Palatine Homes
In Palatine, basement units with PVC sidewall vents are typical. Scale from the hard water and snow at the termination are the faults we see most.
What we run into in Palatine
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
- Hard water. With water this hard, a unit that has never been flushed is usually running hot inside and cold at the tap. Descaling is often half of the cure.
