One of the goals I have is to set up a way to fill from my 500gal tank to smaller tanks
Brent, I had a liquid withdraw valve and pump installed on my big tanks, I had it installed when I purchased the tank, if I done it myself they wouldn’t have filled up the tank. It cost me $300 dollars more for the tank but it included everything, if an LP guy comes out it may cost you more than the $300. It’s always better to have this setup before tank delivery.
