They need to be blown out professionally. They use a very high volume compressor to blow all of the water out of all of the lines. Can't be done by the homeowner.

You can buy compressors with a large enough tank at most hardware stores. Won't be cheap, but in the long haul it may be worth it. The tanks are roughly the size of a traditional gas water heater. Wait for a sale.

I have one of those beasts in my garage. I think I’m equipped to handle the job, I just don’t know where to start.

I hired somebody to come out this afternoon and show me how to do it.

Sounds like you are on the right path then.

I’ve done this with a 5 gallon compressor, it just takes a few cycles. Easier with a bigger tank.
