We have two varieties of fill valves, Heavy Duty Brass or Plastic.
The brass autofill valve is a heavy duty alternative to the plastic valve. While it may cost a little more, it is much stronger and will last longer. Thick brass body and copper float make this valve the best on the market today.
Hudson Fill Valves allow you to maintain fluid levels in you pond or water garden with exceptional accuracy.
Fluid level forces the float to rise and close the diaphragm chamber, which expands to stop incoming flow.
