BRAND NE in box, Recirculating Pump Mounts To The Hot Water Outlet On The Water Heater & The Sensor Valve Mounts Under The Furthest Lavatory In The House Run, Turns Plumbing Into A Re-Circulating Loop, Every Faucet Will Have Hot Water Instantly, On/Off Timer On Pump. We installed ours over a year ago and our bill is an average of 10% lower every month since, I was so thrilled I bought one for my sister's family, and after they relocated they had no need for it so they stored it and later it wound up back in my possession.
