Faulty FAV valve?

[[clone]]

Hey guys,

Finished my install of the HFS-3 a few weeks back but have only just got the time to prime and purge the system and get it up and running. Im not 100% sure however there might be something wrong with the FAV valve. I have purged and primed the pump without any problems as per the first set of instructions. After replacing the 6mm hose and onto the second set of instructions to test the jets, there is no water coming out of the FAV valve. There is definitely water getting to the FAV but nothing it coming out. I have checked all connections and pulled the FAV cord out of the controller and puting it back in ensuring it is in properly. There is no flow on the gauge when i test the system with the SYS jumper. Any ideas? Thanks heaps
