I've started having an issue with my washing machine not fully draining. The clothes are very wet and water is standing at the very bottom. The WM is an old style analog Maytag. I've changed the spinning pump but it didnt help. I suspect the problem is in the hose connection to the waste line. If I disconnect the hose from the waste line and let the spin cycle drain into bucket, it works great. As you can see from the photo the hose goes vertically from the bottom into the metal pipe and is held by a clamp. There is a backflow preventer approximately where the arrow is. I can feel the circle going up/down as I try to clean the path out. The connection from the machine to the metal pipe goes up for about 3-4 feet. As I started reading about drain connection I dont see what I have as standard. What would you guys recommend? Should I change just the backflow-preventer/connector ? Add an anti-siphon of some sort? Redo the whole thing? To get the drain hose to ejector-pump, I'd have to run the hose vertically ~7 feet and then horizontally another 7, probably too far for this machine/pump to handle. Just to explain, the vertical pipe is a branch from a bathroom that ties to another branch below, and then that ties into city sewer line about two feet to the right. P.S. one more clarification - there is very little water left in the machine, so it does drain 95%, I suspect that when the downward water pressure from the machine is on a low side it cant push through the backflow preventer well enough and water stays in the vertical hose.

I bought this house in 2002 and put in some additions which included running copper pipe to a powder room, a laundry room, and a master bathroom. In the past year or so I have been 'blessed' with several pin hole leaks in some of the copper piping. When it happens I remove the old pipe and replace it with new copper. But that's getting annoying! Some of the piping is in a crawl space that I know I can't get into and I'm just 'waiting to see a leak there.. I recently had to replace some piping behind the wall and above the ceiling in the powder room. Is there something I can do with my existing piping to stop the leaks? Thanks. Rich
