Another warning sign that has a very distinct sound is a washing machine line starting to back up. It sounds like a long tube being filled with water. When the washing machine starts to drain you’ll hear the water going down the drain and since it can’t handle the amount of water it’s being given, it starts backing up. As the water gets higher in the line the sound it makes starts to raise in pitch until the head pressure is great enough to force the water down the line. It may keep doing this for a while but eventually it will overflow because the blockage will continue to grow and get larger. Then one day you’ll start a load of clothes in the washer and walk away only two come back in an hour or so and find your laundry room flooded. A washing machine drain line that is flowing properly will have a consistent pitch to the sound while your machine is draining.
So as soon as you hear the washing machine drain line starting to back up give us a call so we can save you from having to deal with a large cleanup and damages of a flood.
