Winterizing with tankless air compressor

I use ours at full pressure and always have for the decades of ownership behind us. (The rig is now 50 years old!) Just be sure to open a faucet or two before you turn on the pump; NEVER run the pump if all faucets are off. When switching from one faucet to the next in order to blow through with air, first turn on the new faucet, then turn off the most recently blown-out faucet.
