So easy to install! Works great.
I had left my hose connected to the hose-bib (sillcock) in a freeze and it broke the old back-flow preventer. So I removed the entire assembly from the house before I realized that you could just replace the little plastic back-flow preventer! Extra work , but I was happy to find this replacement part which took all of 2 minutes to install and it works fine. I even bought a 2 pack so when I do the same thing again in a few years I'll already have a replacement waiting! :-)

Exact replacement for Prier hose bibb
This was a perfect fit replacement for a Prier hose Bibb (spigot) installed around 1992. Saved me 50 bucks and trying to solder on a new one.

These fixed our hydrant after we left a hose connected in the winter
This was a simple fix, and makes me grateful I bought USA made hydrants with repair part availability. I’ll gladly continue buying Prier hydrants for the homes we build

Not for Fusan Faucet
Just a note for my future self. Good product but not for Fusan faucet

Resolved Leaking
This kit fixed a leaking faucet. A little disappointed life expectancy for an expensive bib faucet from Prier, because it started leaking after one year.

Replacement part that fit my spigot
What's there to say? Plumbing parts like this either fit or they don't. This just happened to fit. It only gets 3 stars though since I've had to replace it twice now. It's plastic and gets exposed to a lot of direct sunlight. Over just a few years, it must have gotten brittle. A chunk of plastic broke off and so whenever the spigot was turned on, water sprayed out of the top. But it's nice that I was able to easily replace it.
