Black & Grey holding tank valves
I have a 2005 Open road 31 ft and would like to replace the holding tank valves. Can this be done by a novice? They seem really hard to open and close.

Yes, an easy job.
Check for size of grey water drain. They vary.
The majority of the black tanks are 3 inch.
They use 1/4 on grey and 5/16 bolts on black.
Make sure tanks are empty. remove bolts, four on each valve. Remove old valve. New valve goes in reverse. Good to coat seals with vaseline or the like to hold in place while assembling.
