Drain in laundry room for overflow on 1st floor i
We are building one story house with conditioned crawl space. Laundry room on first floor over crawl space.
The Plumber no longer recommends these drains because of possible insect infestations coming from end of pipe opening outside the crawl space. Says screens on end of pipe have to be checked and do not always work.
Any one deal with this problem. I would think an overflow drain is still preferable to having the possibility of water leaking into the conditioned crawl space.
Any advice would be greatly appreciated!
