Why would I use a HANFLO™ Valve instead of the metal or non-metal valves offered?
HANFLO™ Valves are high performance products, 98% efficient. They are reliable, easy to use, easy to service. The HANFLO™ Foot Valve will not restrict water flow and will maximize pump performance and ease priming. They are made from glass fibre-reinforced nylon for strength and durability and cannot rust or corrode.
How do I know what size valve to use?
You simply size the valve to your pipe size (1", 1 1/4", 1 1/2" and 2"). You may also work out the flow rate of your pump (your pump supplier can help you here) then click on "Which Foot Valve, Which Check Valve" tabs at the top of this page and use the charts provided.
Do I have to remove my valve from the line to service?
No. Your valve can be left in line for servicing. Click on the Assembly tab for further instructions.
I have an existing water line with a 1 1/2" valve on it and I want to replace the valve with a HANFLO™ valve. Do I use the same size valve as my existing one?
Yes, you may replace with the same size valve as the existing valve. Or, you may also visit "Which Foot Valve", Which Check Valve" tabs at the top of this page and use the charts to determine the valve size required. In some situations you may be able to use a smaller HANFLO™ valve than your existing non HANFLO™ valve.
Why won't my Valve seal?
  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 you are using the correct size valve for your application (See "Which Foot Valve", "Which Check Valve" tabs).
What temperature can I use HANFLO™ fittings at?
HANFLO™ 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. HANFLO™ can not guarantee the products will perform when used with temperatures over 60°C (140°F). HANFLO™ products that have failed in temperatures higher then 60°C (140°F) will not be covered by warranty.
