Super easy to install, just screw the Milk Bar™ Pen Waterer 1 to the wall or rail.
Position the drinking hole at around 70cm so the calves can pop their heads straight in.
The float valve has a 20mm riser to easily connect the trough to your water supply and is rated to pressure up to 80psi.
The float valve is set to 8L. If you see the trough is over filling you can adjust the valve with a screw driver.
