The valve operates using a float and control diaphragm. When hooked up to a water source the valve will allow water to flow through it until the water reaches the bottom of the valve and starts to push the float up. As the water level rises it causes the float to rise and seal off the diaphragm chamber. The chamber then fills with water and pushes the diaphragm up to close the valve. The valve will shut-off 1”-2” up from the bottom of the valve depending on water pressure.
How to check the holes in these two parts:
If any of your parts are damaged, a repair kit can be purchased. Hudson Valve and many of our distributors sell repair kits containing all the internal parts of the valve. (Filter, Diaphragm, Retainer Ring and Float)
Please refer to our products page to learn more about repair kits.
The valve will work with gravity feed if you have at least 4 lbs. of pressure and adequate volume.
The continuous flow disc is designed to be used only during the winter in freezing climates. When installed, it will allow the valve to keep a slow trickle of water moving through it at all times. When installed, the valve will not fully shut off. The purpose of this disc is to prevent freezing of pipes during the winter. When using a continuous flow disc, you will need an overflow line to take excess water away as the disc will allow the valve to overflow the tank.
