Product Overview

I recently purchased the Rain Bird CP100 In Line Automatic Sprinkler Valve for a home project, and I have to say it was a great choice. This valve is made of metal with a rubber exterior finish, and it has a 1 threaded inlet and outlet connection. It is designed to be installed below ground so that it is out of sight and away from playful hands.

The Rain Bird CP100 is incredibly easy to install. It comes with detailed instructions, so even if you are not an experienced plumber, you can successfully install this sprinkler valve yourself. I had mine up and running within an hour. The reverse flow design is also great as it reduces stress on the diaphragm for dependable operation.

The CP100 also features an energy efficient, low power encapsulated solenoid with a captured plunger, as well as a Buna N diaphragm which provides superior performance in harsh water environments. This makes the CP100 great for residential or light commercial use. It works with any standard sprinkler timer, so you don t have to worry about compatibility issues.

Overall, I am very pleased with the Rain Bird CP100 In Line Automatic Sprinkler Valve. It has been dependable and reliable since day one, and I have had no problems whatsoever with its performance or operation. The installation process was straightforward and simple, and I am confident that this valve will last me many years to come. If you are looking for a reliable sprinkler valve that is both easy to install and cost effective, then the Rain Bird CP100 In Line Automatic Sprinkler Valve should be at the top of your list!
