for about 40 bucks from a big box store, you can get a whole house filter, a hose bib, and a threaded connector for the other side and 2 carbon filters. 14 bucks will get you a 2 pack of good carbon filters from then on out.
I mounted the pressure reducer to the hose bib side and connect a potable hose to that output side. I will input with the double female ended 6 foot garden hose I made up. I can add either a longer potable to the output, or a reg garden hose to the input.
It is gravity mounted to the ground.
