Fast shipping, item works perfect.
My old ball valve cracked over the winter. Retailers near me definitely did not carry the Zurn 375 3/4" backflow preventer, and most sites force you to buy the entire assembly to the tune of $300-$400+. I'm so glad I found backflow supply. Using the parts numbers from Zurn's website I was able to order the exact piece I needed (in this case the inlet ball valve only). It's an expensive piece at $50 + ~$10 for shipping, but WAY less than buying the entire backflow preventer. My order shipped the same day I ordered, and arrived a couple of days later. It was exactly as ordered, putting it on was a piece of cake and everything is back up and running.
