2 piece washer drain box pieces not connecting
We purchased a new home. The washer drain box is a two piece. The washer connectors and drain are in the top piece recessed into the wall and then the bottom piece is supposed to connect to the top piece. It will not connect and leaves a gap through which you can see drywall. The builder's plumber says this isn't a problem because the drain box is not supposed to prevent leaks from going into the drywall. It may not prevent leaks, but if there should be a leak, the gap between where the pieces of the box don't connect will certainly allow water to go straight down the wall of the laundry room and the connecting wall which is the Master BR wall. This has already happened. They sent a plumber out who said the two pieces could not be connected without cutting into the drywall and then having to repair that. He could not make them fit together and put some silicone over the gap which did not hold and the gap between the two pieces started again.
