The Drip-Well System comes in three sizes. The standard equipment oil reservoir is a small metal container holding only enough oil for a few days. The biggest negative is that these draw their oil from the bottom of the tank where rust and condensation accumulate to plug the needle valve. Drip-Well addresses these problems by providing a poly tank large enough in most cases to last the irrigation season. More importantly, Drip-Well does not take oil from the bottom but from the interior of the tank.
Condensation settles away into a sediment bowl where it is harmless until drained.
This valve has been tested successfully for 7 years and has been marketed across the United States to a diverse group of water users.
