## Description

Product Description Rain Bird CP100 In-Line Automatic Sprinkler Valve, 1" Threaded Female Inlet x Female Outlet. Rain Bird manufactures only the highest quality In-Line valves. This residential and light commercial grade In-Line valve replaces all in-line irrigation valves installed below ground with 1" female threaded inlet and outlet. For use with any 24 volt AC irrigation timer/controller. Unique reverse-flow design helps prevent flooding in the event of internal diaphragm failure keeping the valve closed and saving water. Valve operates automatically or manually with manual bleed screw. Buna-N (nitrile rubber) diaphragm offers superior performance in harsh water environments. Features an energy-efficient, low power encapsulated solenoid with captured plunger. May be used with all types of watering devices including Rain Bird spray heads, rotors, and impacts. In-Line valves are installed below ground in a valve box downstream from the main line from a PVB or double-check valve. After installation and before startup, always flush the system of dirt and debris manually using the valve's external bleed screw. In-Line valves will not prevent back flow on their own; they require a back flow prevention device. Use In-Line valves in locations where the use of a pressure vacuum breaker (PVB) or a double-check valve is required by city codes to protect against back flow. Check local city codes to determine what type of valves are required. Also available (sold separately) in 3/4" model: CP075.

Review: Work Great ! - Works like it should. I had to buy adaptors because apparently I can no longer tell 3/4 from 1 in PVC. LOL
Review: Great replacement part for my Drip System. - My old valve from DIG was leaking and rats had chewed the wires. I bought this and replace in five minutes. It seems very nice, secure and watertight. Rainbird is Great. I did put some gorilla tape on the wires to disuade the rats (maybe squirrels), but need to add some other deterrent.

## Questions & Answers

**Q: Can this be used with 3/4" pipes by using 1" to 3/4" pvc reducer? i have 3/4" pvc inlet does it help using bigger valve?**
A: 1'' valve fine using 3/4 piping on exhaust side, try to feed with 1'' on supply side for the volume, if coming off 5/8 meter go thru shutoff valve and backflow with 1'' to feed valves, have fun, i would use 1'' on exhaust, then to smaller pipes if on irrigation

**Q: Will this valve work to supply drip irrigation emitters or is there a different valve for those?**
A: It will work. Just make sure to buy the filter that is used for drip lines so the emitters don't get clogged up.

**Q: I am currently using 3/4 inch ball valves to change flow from one circuit  to another. Will this valve have the same flow capacity as the ball valve?**
A: The same or better-----I think my inlet's and outlets are 1"----you will have to use reducers to adapt 3/4 " pipe.  Please note that these valves are solenoid operated valves----as used with many electric 'timer' systems.     I've found these solenoid valves to be trouble free over the many years that I've used them.

**Q: I have a rainbird controller with 25.5v is it compatible with those valves?**
A: Yes. Believe the valve is rated 24 volts  +or-  . 
Be careful not to over tighten threads !
