Yes the kitchen is in one of the slides I will have to check for a kink but I can see the antifreeze in the lines up to the faucet (it has been winterized). I have removed the faucet from the MH took it apart and blew it out with compressed air disassembled it blew all the parts out with air nothing changed when I re-assembled it. I can't blow air through it when it is assembled but I can blow air through each part when it is not assembled. There is a little plunger valve for the sprayer I took it out also and blew it out. It just doesn't make sense to me.
I plan to replace it with another faucet I think the problem is in the valve that allows the sprayer to work and yes it is separate and not one that pulls out from the end of the spout. I have not tried it on city water because I winterized it already I removed the faucet thinking I could just clear a clog.
