Yikes, draining under the house?? When I was a kid we had that issue come up in an older home my Dad was modernizing. Had to stop the water ASAP to prevent the pier and beam foundation from shifting around.![]()
A guy I know told me that his son bought an older home last year, and added a new high-tech washing maching when he moved in. The washer output such a high pressure on the drain water lines that it blew the old iron piping joints apart under the house! He had to replace all the lines with PVC as well.![]()
