Thanks Guys. I tried again and it worked. I had to increase PSI to about 60 initially and BFV sealed. In some cases i had to remov air hose and quick connect it again after pressure built in. Anyway done with my 9 zone for this year. I might do it one more time over the weekend but it was nice...

Thanks guys. I am most concerned about winterizing the pipes after BFP. The BFP and pipes below that can easily be drained as i have a drain port in basement after sprinkler shut off. CNGsaves you mentioned " cut a T ... inside house between the shutoff valve and exterior wall". Won't that be...

I think the general thought is that if it can withstand the water pressure it can withstand 40-50 PSI that is used for blow out. Looking at the internal it seems the bottom test port should have worked better. May be the puppet comes down anyway and pressure is not good enough to lift it up...

Thanks theoldwizard1 why do you do second step "Open the hose bib half way" just to drain water between house and BFP as much as possible? I am doing the same thing as you described and using top port (after trying from second port bottom one). The problem is that it worked for two zones after...

So i took out top of BFP and attached are picture. It seems it is not easy to pull up baffle. It seems it comes from up from water pressure. Anyway i put it back in and tried again. And it worked for couple of zone and again air started coming out. Do you think it will be better to blow out...

The BFP is febco 765. What could that loud sound be when air was not leaking from second port (bottom one.). Should i use top test port or bottom? Could i have damaged BFP? How do i know that I haven't. To connect air hose. I removed test port then went from 1/8 to 1/4 then added 1/4 air plug...

I don't know if it matters but I couldn't find 1/4 inch flare fitting so i took out test port and fitting my air hose in 1/8 opening on valve. Also if BFP is closed how to reset it.

Hi, I am trying to winterize my sprinkler using instruction in following thread. http://www.garagejournal.com/forum/showthread.php?t=221613&highlight=sprinkler My setup is similar to the picture shown. I was trying with test port 2. First time i tried it was making a loud noise near BFP and...

Sorry Guys if this has been covered. I am trying to winterize it first time so will be safe than sorry. My setup is almost same as setup posted by Mattguy with two test ports and a drain port before the back flow preventer (bfp). I don't have blowout port after bfp. 2 questions. (1) Reading...
