On day two of a long trip. This morning when I went to dump I hit the switch to open the valve and water started flowing. In the past when you hit the switch you could hear a noise for a short time and then stop. Closing was the same way. Today the noise did not stop until I let off the switch, Same with shutting the valve. Does anyone have an idea as to what I have so I will have a better idea when I dig in. It sounds like a keyway has fallen out or broken.
I finally got the front cover loose enough in order to get some pictures. Here are pictures of the valves. Now to get a new valve and get it installed.
Call the number on the valve and tell them what is happening. They have great customer service.
