I'm in a brand new house and I'm wondering if my laundry drain was installed properly. It's raining outside and I am hearing water though the wall drain for the washing machine. I removed the washing machine flex drain pipe and there's no water coming from it, and there are no leaks by the valves or hoses.
I assume that I am hearing water coming into the drain from a vent. Should I be able to hear the water flowing through the drain? I can also feel some air flow through the drain, so I am guessing that there is no trap (I ran water through the drain to confirm the trap would be full if present). Should there be a trap?
