Description

Replacement inspection plug found on the 3350 E-fount and the older style 3360 waterer. The inspection plug is used to access the valve and float system in the units.

The inspection plug is fully insulated to help keep the water cooler in the summer, warmer in the winter. Use gasket piece 712 to create a seal against the wind and cold in the winter.

Winter prep reminders, parts alerts, nothing else

A few emails a year, sent when it matters. Heat kits before the freeze, valve rebuilds before spring turnout.
