Auxiliary on demand water pressure boost pump. Plumbs in anywhere in your home, plugs into any 110ac (regular house hold outlet). Great for faster fill times on small ag 4x4/SXS sprayers, filling summer time pools or use on a wildfire suppression skid/system. Very versatile and I've got extra fittings that may suit your needs.
Priced OBO to move quickly. I won't be offended :)
