What's the appropriate way to trap a (residential) air handler condensate drain so it doesn't pull sewer gases into the house during heating season? This is a pull-through air handler: the condensate line is under negative pressure when the fan is running.
The 'professionals' who installed my AH installed a P-trap on the air handler, which is directly plumbed into the drain for a seldom-used laundry room sink, upstream of the sink trap. Needless to say, during heating season I have to run the sink every few days to prevent the trap from drying out and allowing sewer gas into the house.
Is there a more permanent solution here?
