Question for "Blow Out the Water Line" gurus
I have always used the pink stuff, but am thinking of coming over to the dark side. (DW asks "why"?) My question: There is pex tubing from the water pump to the first junction going up to a faucet/...

What is a recommended compressor tank size to be able to do a reasonable job of bowing out the lines at home? If not 3 gal. or 6 gal. then what? Is there a way to use the FW tank as an expanded pressure tank and then run pump and open valves one at a time? Assume you would need to seal off the FW fill vent tube but are there any other vents to a FW tank?
I have a 7-gallon portable air tank (I've always had a separate compressor) which has worked fine for blowing the lines for 15 years.
I pump it up to 90 or 100 pounds of pressure to start. Since I have first emptied the water heater, I have no cause to worry about over-pressure, because the empty water heater will fill with air, so the pressure in the water system will be half or less of the pressure starting out in the air tank, even if I did not open a faucet before turning on the air.
