My air conditioner is in a crawl space in the 2nd floor. The condenser tray has a PVC drip line that comes down through the wall and meets up with a bathroom sink's drain immediately below the crawl space. When the A/C runs there's a small flow of water that you can barely here, but for 2 hours after the air conditioner stops there's a single drop of water about 1 per second and it's very loud. So, loud you can hear it in the bedroom next door even with the door shut. Is there anything I can do to reduce the sounds of the drips? I'm not sure if the drip is the 8 foot drop from the floor above in the wall or where the PVC finally connects to the drain line.
The green-painted PVC coming out of the wall is the drain line from the air conditioner above.
