Greetings

I have ordered 4 check valves to replace the old one.

My questions are:

1-The 2 color check valve ( Green and white) have
different number on each .

Are they just the same??

From the outsideThey sure look identical but I am just
wondering why the part number is not the same.

2-How about the 2 greens check valves ???

Thanks all
Serge

I don't see a good reason why it would matter, they all do the same thing. Whenever you replace them, just do one-by-one and replace them with identical ones.
