Plumber here, thank you.

Could you provide the link to the next video, I can not seem to find it or any information on how to perform a 2 inch drain check on a dry system. Thanks.

nice video

Excellent

Actually expanding the intermediate chambers peruse for the air to hold the clapper down with air above to hold the water back is the true story on how a dry value works

Is the pressure from the air portion contributed by the weight of the lid separating the wet and dry interface?

Nice

I believe I released too much air during the monthly drain down or not fully turn off the water valve; I don’t know so I got a red light in my fire panel. Can you explain what triggered the panel light ? Was it the accelerator pushing the clapper up ( but after opening it chambers the clapper was close) or the air pressure switch.

How do you set it up?

I need to know a name of a part.

Dose the water fill all the zones or only the zone with the fire in?

ASBasf water is supplied to all the connected piping, but only come out of the head which has burst due to fire.

Hi, have a question. If the dry valve is tripped, do you still have fire protection of that area. If so what is the downfall of it being tripped and not reset in a timely manner.

Joey Winstead as long as the main control valve, water supply valve, is open, you will have protection. Unless of course the system has froze in areas. Tripped systems should be restored ASAP, or if it can’t be restored, a fire watch put in place.

@@caldershot9702 Hi, thanks for the reply. Still alittle fuzzy. I understand if the main water valve is left on u still have water to the lines, but what happens if there is a fire and the system is tripped I guess I should ask.

Joey Winstead if the system is in fact tripped, the lines will be filled with water, if the main control is still open, it will operate like a normal wet system. Of course you will not have alarms though. So you could leave the system “flooded” , but you would still need to perform an hourly fire watch, or whatever is recommended by the authority having jurisdiction.

How do you test the flow switch without tripping the system? Since from my understanding a periodic flow switch test is required but trip testing much less frequently.

Just do both, it doesn't hurt to do extra tests!

Dry systems have an alarm test valve for testing alarm flow switches. Otherwise you would do a throttle trip. That’s a way of tripping the system without introducing water to the whole system.

@@caldershot9702 that’s very true. It is fed from the water below the clapper. This allows you to test the bell/water motor alarm and pressure switch together.
