I looked at the spray video, the water seemed to flow back into the tube, can you explain why this was happening. Theremight be a possible leak at the flow sensor? Perhaps there is a small leak an dcaused the low flow reading?.

 

I just check all my hoses, and there is a leak Leaking from the Flow Sensor on both sides, and the Solenoid Valve on the 4mm side. Anyway to fix these problems, or do i need to replace these units?

 

You don't have to replace the sensor but the two push-in fittings. We have now replaced them with compression types (806-393). They are available at howertonenginering .See picture below:
