PAUL G. United StatesSimple, inexpensive, effective
I've never blown out a sprinkler system before. I now have a new house with a 300 series Zurn backflow valve. Since I have a $300, 100 psi air compressor with a 20 gallon tank, I invested about $25 for this adapter. It made the job simple. I set the regulator down to 30 psi and did the job according to the Backflow Supply how-to video on YouTube. Simple. Many thanks.

Anonymous United StatesThey had it! Fast Shipping
All the other suppliers/websites I visited for this part were backordered two months! Backflow Supply had it in stock and shipped it out fast!

Perfect saves me over 100 a year winterizing my own sprinkler system.
