When PVC condensation line is routed from first floor furnace to sump pit in basement, is the PVC required to be fastened to the sub floor joists until it reaches pit area?
When the PVC is tapped into a sealed system, should rubber bushings be placed around the PVC to prevent vibration noise?
What in Gods Name are you talking about----:p—
AC installer want to run PVC discharge along floor into sump pit. I say no way…
I want it to run along the joists then straight into pit. Wondering if there are specific installation requirements for discharge lines into sump pump.
