I'm running a drain along my basement wall for water heater overflow, a dehumidifier, and for air handler condensate. I've been running sch40 PCV, but I don't know how often it is required to be supported with clamps. If diameter matters, I started with 1.5" and worked down to 1" at the end. Anyone know the support spacing?
