Question:
Hi, I have this Valterra T80 double rotating sewer valve on our Coachmen camper. The valve assy. is only 3 years old and I have a small leak and just want to replace the seals. What sufffix to the part numbers do I need: 1001-? and 1003-? I assume the suffix: -9VP or -9PB are different shapes?

Hey Phil, thanks for reaching out!
For a 3-year-old Double RV Waste Valve Kit # T80 you need the -9 versions which are parts # T1003-9VP and # T1001-9VP. You would use the -7P seals if you had an older system.
How often have you used the valves?
