The valve operates using a float and a control diaphragm chamber. 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. As the water level rises it causes the float inside of the valve to rise allowing the diaphragm chamber to fill and close the valve.
Make sure that your tubing/pipe is of an adequate size:
• For the ½” Valve – no smaller than ¼” and no bigger than 1”
• For the 1” Valve – no smaller than ½” and no bigger than 2”
• Do not use pipe compound.
• Use plumber’s Teflon tape on threads of water supply pipe.
• Screw Hudson Valve on to water supply pipe; hand tighten only.
• Turn water source on full volume.
• Make sure valve is mounted stably – the valve will not work if it is not secure.
• The valve cannot be submerged.
• The valve must be mounted vertically.
The valve will shut of about 1 ½”- 2” up from the bottom of the valve depending on pressure (the higher your water pressure the higher up on the valve the water will shut off).
NOTE: there will be a short delay in shut-off the first time the valve is used while the control chamber fills with water.
• The Hudson Valve is designed to be used in water.
• We only recommend using it in water.
• We will only warranty valves that have been used in water.
• This is not to say that the valve will absolutely not work in other liquids. We have customers that use it in a variety of liquids, but we have not tested it in anything other than water, and thus cannot recommend its usage with any other liquids.
• We do know the valve will not work with salt water as the supply source.
To check the holes take the valve apart:
If none of the following suggestions work, a repair kit will be needed.
Hudson Valve and our many of our distributors sell repair kits containing all of the internal parts of the valve. Please refer to our products page to learn more about repair kits.
The water hammer can be caused by too much pressure build-up behind the valve. Under high-pressure conditions, installing a pressure-reducing valve before the Hudson Valve may alleviate the problem.
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.
