Why do you disassemble the valve _after_ testing its function? This way there's no opportunity to notice that the reassembly is incorrect in a way that reduces flow.

is there a way I can test the water flow switch without tripping the Dry Valve? thanks..

[@silcofireandsecurity]

Yes, there is a way to test the flow switch and not trip the valve. Depending on where you live and the regulations in your area, we recommend to have your inspector there to perform the test.

1 Put the system on test call alarm company. 2 close the piv or backflow valve. 3 close the control valve. At the alarm valve Make note of the alarm panel readings for each supervised device ie. backflow or piv. Control valve. Close the air supply ball valve to the Alarm valve located at the compressor. 4 Open the water flow device/Switch with the key provided by the manufacturer. 5 manually engage and hold down the stick lever in the middle of the device for At least two minutes make note of the time detection is achieved. Revers the process. Clear the panel.

Many dry pipe valves have an alarm test valve. It comes from the bottom side of the clapper and goes into a tee that feeds the high pressure switch (water flow switch). It allows you to force water into the pressure switch with no risk of tripping the system.

Theres no flow switch on a dry riser. Youre talking about a wet system. You can trip the flow switch manually by opening the cover and pressing down on the little black lever.

Man that's an ugly Dry Valve.

Unfortunately they are not all pretty unless it's brand new, even then - some are questionable.
