• What Size Gate Valve Is Needed To Replace The Gray Tank Waste Valve
• Yes, gray waste valves are 1-1/2". If you're replacing just the gate valves for your double waste valve then you can unbolt them and slip in the # T1003VP for the black and # T1001VP for the gray and then bolt them back in place. I've attached a video below where you can see how to do this. If you end up needing to replace the entire double waste valve then shoot me a few pictures from the other side so I can see the direction of the piping to find the correct replacement.

• Should Tire Pressure be Inflated to PSI Rating Marked on Tire?
• Inflate your tires to 80 psi cold like is marked on your tires now. The tires that were originally on your fifth wheel are almost certainly different than what you have now, which is why the spec sheet has a different psi. To get the best performance and keep the maximum load capacity you want to follow the psi that is on your tire at the moment, which is 80.
