Filter Sock for the Foot Valve to help filter and stop particles entering the Valve.
Foot Valve Sock Fits Foot Valve 50mm to 63mm.
You will need to refer to the Choosing the Correct Foot or Check Valve Page under the Technical Info / Pressure & Flow Rates Tab of each valve product and use these charts to determine the valve size required. In some situations you may be able to use a smaller Hansen valve than your existing non Hansen valve.
No, as the high concentration of chlorine used in the water for pools will attack the material. The fitting material is only suitable for use with domestic water. Hansen products that are used in this application will not be covered by our limited lifetime warranty.
The spring in the valves is made of 302 grade stainless steel, and may eventually corrode in the salt water. The spring is available as a replacement part if required. All other parts of the valve are fully resistant to salt water.
No. Your valve can be left inline for servicing. Refer to Re-assembly instructions for further information.
Work out the flow of your pump (your pump installer/supplier can help you here) then refer to Choosing the correct Foot or Check Valve under the Technical Info / Pressure & Flow Rates Tab of each product.
All check valves should be screened upstream. The advantage of the Hansen Check Valve is that they can be serviced in line if your water is dirty.
Yes, the Hansen Check Valve can be serviced inline and any parts replaced if required.
Yes the Hansen Foot Valve has been designed with the ability to work in dirty water situations and because of lower head losses of this valve you can select a smaller size than you normally would expect, thus with the higher velocities across the diaphragm the valve becomes self-cleaning.
No, although pumping sand is unadvisable because of the damage to your pump. You will find with the screw cap service access to the Hansen Foot Valve you only need to replace the parts that wear in these circumstances. Another suggestion would be because the Hansen Foot Valve can be installed at any angle you may be able to install the Hansen foot valve vertically above your suction pipe and keep it above the sand.
Hansen have tested all its products for use with cold water up to a maximum temperature of 60°C (140°F). We do not recommend the use of these products with temperatures higher than 60°C (140°F) as plastic expands due to temperature increases. Hansen cannot guarantee the products will perform when used with temperatures over 60°C (140°F). Hansen products that have failed in temperatures higher than 60°C (140°F) will not be covered by our limited lifetime warranty.
No not necessarily, again because of the higher flow efficiencies of the Hansen Foot Valve you match your flow with the head loss your pump can afford, generally you will find the Hansen Foot Valve size will be less than the pipe diameter. To choose the correct sized valve for your application, refer to the Choosing the Correct Foot or Check Valve Page under the Technical Info / Pressure & Flow Rates Tab of each product.
1. There may be something sitting between the diaphragm and diaphragm seating area. Pull the valve apart and clean out (replace diaphragm if damaged) as per assembly instructions.
2. Check to ensure that you are using the correct size valve for your situation (see choosing the correct foot valve or check valve).
