Zane Solar Pool Heating Australia designs and manufactures it own check valve that is reliable and solidly strong.
Its simple split construction facilitates easy installation and service and is manufactured from long lasting materials.
Check valves are used to ensure the flow of water in only one direction, and these check valves from Zane feature a replaceable sealing element and O ring seals.
Check valves are essential for solar water systems and should be installed in line after the filter. This is to ensure that the hot water flows towards the pool and not back through the filter.
It is necessary for solar boost pumps to have a check valve with a small bypass above the outlet to minimise impeller spin off and damage. Zane pumps incorporate this valve already, but other makes also need this addition.
Additional information on check valves for solar boost pumps is available from Zane Solar Pool Heating Australia.
