These are good at what they do and built well enough. If you wanted the control of the faucet out by that garden the advantage is its convenience. One could put an inline valve on and coil up the hose on the ground and get a similar result. How it is plumbed would be the question. A lot would depend upon your surroundings and how temporary or permanent this is. You could simply use a length of garden hose from the house valve to this. You could buy a coil of water pipe and adapt it to a hose or make a more permanent installation. Whether or not you shut the line off at the house would mostly depend on your confidence in your supply line I'd think. the valve on the unit is a standard brass water valve.

Why not just buy a 150 or 200' 5/8" water hose and a Lewis hose reel?

Mean Green Industrial Grade is a good quality hose and Lewis makes a great reel that will hold a 200' hose.

FWIW, I just bought some 3/4" black plastic pipe, the kind used in wells, and dug a shallow trench from the hose bib to where I wanted it. Couple of connectors, another hose bib, some Els and it was done and the water is there when I want it. I didn't make a permanent connection to the house, just a hose connection near the existing hose bib, just connect a hose and you're in business. Consideration should be given to draining the underground pipe in winter. If your land slopes fine, if not, be creative with a ladder and RVantifreeze until it comes out the other end.

Good luck,
