350LE Classic dump valves replacement

Hi..I need to replace both the grey and black dump valves on my newly acquired Airstream 350LE motorhome. The Owners manual does not list the part numbers for these two valves. Has anyone found out the correct Thetford valve part numbers and located a scource. Also, any hints as to how to approach the replacement job would be much appreciated. Thanks

Since you have to do this, my suggestion is to change over to the industry standard of Valterra. All new Airstreams come with Valterra. Parts are easier to find and less expensive. You can also in a regular connector(Valterra) at the same time.

Parts can be found at Camping World in New Braunfels or any of the RV Dealers in your area.

I would stay away from the Airstream dealer in Buda. Have not heard good things from them.

I absolutely agree on all counts. I'm kind of hoping to free-up the dump valve with PeterH this weekend so as to hold-off replacement at this time. Also agree with your comment re the Buda Airstream dealer who I've had dealings with! Pity particularly in Austin which loves its Airstreams and deserves a committed and Airstream community minded dealer!
