Good call, Grumpy. Interestingly, the manual from our Seneca is pretty light on instructions for using air:
Air pressure
This method will utilize an air hose to blow excess water from the water lines.
1. Make sure all holding tanks are empty and drain valves OPEN.
2. Run the water pump until it is dry, this will take approximately 15-20 seconds.
3. OPEN all faucets and drains, and the toilet.
4. Using an air hose and adapter (customer supplied), blow air through the city
water connection. Any remaining water will blow out in five to ten minutes.
Pour one cup of non-toxic RV antifreeze into all drain P-traps.
I found step 2 surprising - they don't mention pulling antifreeze through the pump.
