I have what I think is a check valve connected to the aux pump via a line going to my air-driven awning. I am sure it is leaking back toward the pump. Does anyone have a part number for this check valve? I attached a pic.
Royce,
That looks like the fittings are 1/4" but it is hard to tell what size the fittings are for sure. If they are 1/4" that is a Haldex KN-23080. Here is a link to the various sizes that they are available in. http://www.plazafleetparts.com/uploads/2/1/9/0/2190100/pressure_protection_reduction_check_and_other_valves.pdf

Part number is also stamped on the unit
Royce,
Just pull it off, and take it apart. It is probably just a flat plate held in place by a spring. Many times you can clean these out, lubricate them with a little silicone grease, reassemble and they will work just like new. Certainly worth a try!
