120L Impact Resistant PE Livestock Auto Waterer With Quick Drain Plug For Dairy Barns

120L PE Auto Waterer for High-Traffic Dairy Barns

The 120 litre trough in this range is built around one idea: a group of cows should never queue for water. A wide open basin with a 120 L reserve lets six to eight animals drink in a single visit, and a shielded float valve refills at high flow so the level recovers before the next group walks in.

Construction

Rotomoulded high-density polyethylene forms a seamless double wall. There are no joints to leak, no metal to rust, and the surface stays smooth enough that biofilm has nowhere to grip. The shell is UV stabilised, so it keeps its strength after years of direct sun in open pasture.

What the design solves

• Kick and head-butt damage: flexible PE absorbs impact and springs back rather than cracking.
• Slow cleaning: a large quick-drain plug empties the basin in minutes and smooth inner walls wipe clean with a brush.
• Winter icing: the trapped air layer between the two walls slows heat loss, so ice forms later and thaws sooner.
• Valve tampering: the float sits behind a moulded guard, out of reach of curious noses.
• Movement: four anchor points on a reinforced base keep the unit level on slats or concrete.

Technical data

Installing and running it

Set the trough on a level pad within reach of a 1/2 inch supply line, anchor the base, then adjust the float arm until the water sits about 20 mm below the rim. Check the valve screen monthly in sandy areas and rinse the basin weekly. In hard-water regions a vinegar soak lifts scale from the valve seat.
