Sewer Dump Valve

[al perna]

Chuck , we had the same issue back in the spring . I drilled a hole in the back wall , removed the handle on the dump valve and was able to slide the rod out of the way. . This allowed me to have access to the valve body without removing the air lines . We were not able to remove the flap with a hanger so we purchased a 9" long pair of needle nose pliers . after a few tries we were able to remove the flap and install the new paddle . Steven Brittles , of Dupree Products shared the time saving hole tip . After that experience , we will lubricate the dump valve each year . It is so easy and failure to the valve is quite inconvenient.
I must say if we had the camera, it would have saved a lot of guess work and time .
