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/...

I would still recommend using a regulator even with a portable tank..
This allows you to turn on the air at a slow controlled rate instead of shocking the water system..
Fortunately for myself I can reach my RV via 75ft of air line.. Otherwise I would use my small pancake compressor.. Doing so eliminates the short coming of a small air tank supply.
I understand that I cannot have a sudden "explosion" of high pressure into a line that is full of water. However. . .
1) Turning on the air with the portable tank is necessarily gradual, as it requires about 3 or 4 turns of a little valve in the outlet, and
2) In my case, the water system is pretty much empty because I have already drained the water heater and opened up the low point drains.
If I had more than 50' of air hose, I might use my compressor to do the job. It has a pressure regulator for the output, which I would dial down to an appropriate pressure. I find the portable tank more convenient for me personally.
Not trying to argue, only intended to answer the question of how big a tank folks have found satisfactory for blowing the lines. For me, the 7-gallon tank has been sufficient.
