Water pump

In November, I (sorta) winterized my 2017 Hurricane 32S unit. Meaning I added 7-8 gallons of food-safe antifreeze to my fresh water tank (diluted) and ran it through the system. Also put some in the p traps and holding tanks... I say ďsortaĒ because I didnít bypass the water heater - didnít have the parts or tools and didnít think it was going to get that cold.... I live in the south. (Lazy)

Last weekend I flushed the entire system with fresh water and went for a little trip. The water pump made a light knocking sound like a water hammer most of the trip and the water pulsed from the spigots after a second or two of running. It also feels like I had much lower pressure than I did before winterizing. We did get a few freezes this year but I have not found any leaks.

Iím not sure where the pump is - I suspect itís below the sink in a very inconvenient spot... any ideas on whatís going on and how to fix it? Thanks in advance, all you road warriors!
