Brand new water pump now losing pressure.

Thanks for the image. Looks like I'm going back into the "basement" to see what I can see. I saw no hoses going to nowhere, so to speak. I'll let y'all know what happens in the end. I hope it's a happy ending.

And yes, the pressure decreases after turning on, which is what it did when I first noticed a problem with the first pump and before I noticed the wet floor. That's why I'm saying it has to be something other than the pump, causing this to go down hill.
