water lines / winterize

[gbaglo]

I'm pumping RV antifreeze through the city water inlet with a hand pump. Normally, that doesn't take much effort, but today it's like trying to pump with all the taps closed.

I have drained the fresh water and opened the low-point drain ( and closed it ) bypassed the water heater and removed the anode, I've run the water pump for 20-30 seconds.
Wife is inside opening taps. Got pink out of the cold and hot taps at the sink, but in the bath, it's not coming and pump doesn't move.
Anybody have a clue?

I'd check that the screen on the sink output isn't clogged, and that the shower diverter isn't pulled (with the shower button closed).

Back at it tomorrow. I removed the shower head entirely since I can't remember which way is on.
