Tankless Units in Maywood Homes
Most Maywood homes keep the tankless in the basement near the floor drain. Harsh winters, snow at the vent and hard water all leave their mark.
What we run into in Maywood
- 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.
- 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.
