The patented, all stainless steel Edstrom nipple is a simple, yet rugged, design that operates without the use of troublesome springs, orifices or screens. The design uses a lever, or stem, which the pig moves by biting to release water into its mouth. When the pig removes its mouth, the lever is returned to its closed position by the elastic force of the silicone rubber diaphragm. The diaphragm can be flexed millions of times without failure; it is not subject to breakage due to corrosion or mineral buildup as are springs. A standard O-ring is used to provide a positive water seal.
Edstrom nipples will work on gravity or pressure systems up to 50 psi. All waterers have a 1/2" MPT connection, and the threads are wrapped with Teflon tape at the factory. This means you can quickly install Edstrom nipples in your brackets without having to apply messy pipe thread compounds or sealants.
Variable Flow Feature
The flow rate of water discharged from Edstrom nipples can be varied by adjusting the tightness of the Retainer Screw. By tightening the Retainer Screw the water flow is reduced. This Variable Flow Feature eliminates the need for orifices and their protecting screens which easily plug and stop the flow of the water.
In the Nursery, piglets need plenty of clean, fresh water to get maximum growth. Edstrom Nipple Waterers are made to withstand harsh treatment from hogs and remain leak-free, saving you water and money.
In three different tests we found the Edstrom Nipple saved water over the competition.
Based on a water cost* of $2.10 per 1000 gallons, yielding a $613.20 annual savings per year for a 1000 pig nursery house.
1000 pigs x .8/gal/hd/day SAVED=800 gal/day
800 gal/day x 365 days= 292,000 gallons per year
292,000 gallons per year x $2.10/1000 gallons= $613.20 savings per year
*water cost is based upon an independent study involving electrical cost of operating pumps to deliver water to hogs and pump waste from the lagoon.
