Winterized backflow preventer-question
Posted on 1/4/15 at 5:21 pm

I rotated the two test cocks 1/4 of a turn as instructed to drain, but they have been draining for 10 minutes showing no signs of slowing. How long should it take to drain?

Have you shut off the water inlet?

What style of BP is it, and model?

What I was thinking.

I guess not. Any clue on where this is located?

Depends on how much air is in the system. The VB should be at the highest point in the system so it shouldn't be draining the entire volume of the system through it.

Turn off the supply valve and turn of your controller. If you are draining it but have the supply valve on it may take until the Tigers win another NCAAF Championship to drain it......although it wouldn't freeze.

If not, remember that if you BFP is below a pressurized line it has to drain all of that piping before it stops.
In which case, you BFP is worthless.

I'm following these instructions:
Winterizing your backflow device properly is easy, will save you a great deal of money and only takes one or two minutes:
1. Shut off the water to your sprinkler system at the main valve or stop-and-waste.
2. The next step will require a standard small flat head screw driver. Drain the water from the backflow
preventer by opening the test cocks. (There are 2 test cocks on the side or top of your backflow
preventer), to open them turn the little screws 1/4 of a turn.
3. Turn the valves on either side of the assembly 1/4 turn so they are not completely closed or open.
If properly winterized your backflow preventer should be able to sustain the cold winter months.
My issue is the main valve I guess

Yep. Sounds like your inlet valve is leaking by.

I can say with 100% certainty that functionally you are now winterized.

Um, no.

BTW, 600 WOG is probably not the model. WOG = water, oil, gas... meaning it's suitable for all of those uses.
600 is probably an air pressure rating.
What type of system is this in? Industrial or home?

Home. I think my problem is locating the main valve. I'm guessing it's where the valve is that shuts off water to the entire house but the box is full of water.

Ah, sprinkler system. You're right about the main valve. You still have pressurized water coming into the BFP and it is just draining out.
Leave your BFP as is and fix the issue on your main supply side.

I don't know much about sprinkler systems, but I would suspect there is some sort of shutoff right before your main inlet on the distribution point in the sprinkler system. That's the one to close.
Doubt it would be in the meter box unless you have a separately metered sprinkler system.

My water shutoff valve underground is stuck - can only get a half turn. So I just wrap mine in a sheet/tarp and pray.
