Winterizing Issues

What air pressure were you using? You could have blown off a hose. When I blow out my lines I drop the pressure to 20-30 PSI, some say 10-20 PSI. Water does not compress like air so you must be careful when pressuring your plumbing with air. I hold my air hose up to the fitting and only let a little in and then pull it away then do it again. I also make sure the sinks have the hot and cold open so I don't build up to much pressure

Is it possible that something blew into your kitchen sink faucet and plugged it up?? Perhaps it plugged up just the small screen at the faucets end ?

I think Jasp is onto a reasonable probable cause.  I have used compressed air on my 177 for 5 years and the pressure is 60 psi, have never encountered any problems at this pressure and as I have stated in earlier posts, takes about 1 minute to go through both sinks, shower and water closet.  I do always keep one line open so pressure does not build up too high.  My brother got me started on this method as he has done it this way for over 10 years now, same pressure, no issues.

I did go the antifreeze route the first year I owned our pod in 2011.  After using about a dozen different formulas to get that nasty taste out of the lines, as we use it for drinking water as well, I said never again will I use antifreeze, and I haven't.  This way is much quicker, more efficient, and a lot cheaper; I use about 1 pint of antifreeze each time I winterize the 3 traps (2 sinks and 1 shower).

Take off the aerator before you try anything else.

The aerator is the little filter thingy screwed on to the end of the faucet.  It's what the water finally leaves the faucet from.  It's got several screens in it to catch debris.  It's not uncommon for it to totally clog.  I leave mine off, so I don't get that soft stream of air-filled water, but I do get water.
