I have Grundfos UPS 15-58 FC circulator pumps on my system. Ordered 2 replacements and what came was UPS 15-58F. They are black vs.red. I can't find out what the difference is and as I bought them on an ebay store I would rather get my info else where. They are returnable.
So thoughts??
Thanks!

The FC should have a check valve, does the Fs you recieved have them?

The FC has a check valve. The ebay vendor replied saying the F was the commercial version and that the check valve was in the box which it is not.
I have inquiry into Grundfos about the difference between the 2.

Is it by chance already installed in the pump ? a little white cartridge?

So the pumps that came were not what was ordered. I could not see and indication of a check valve.
The ebay seller was not responsive so I contacted ebay. They gave him 5 days to send a return label. He didn't follow through. This morning I had an email from ebay stating the issue is not resolved, I received a total refund back to my Paypal account and I get to keep the pumps.
So I thought to send a note to the seller. He responded saying "I don't know how you pulled that off". I replied "You had the opportunity to handle this but for some reason you chose not to".
Well that saga is over! Now to buy the correct pumps!
