Cannabis Irrigation supply carries many sizes of Schedule 80 PVC risers. 1/2" and 3/4" pipe thread and in lengths of 2" to 12".
Use these to connect Drip manifolds to water supply lines and hold them above ground level for easy access.
This 20 PSI pre-set regulator is made to go on a 1/2" sprinkler riser. Has built in check valve, so will not create run off. Valve opens at 25 PSI on start up and shuts off at 10 PSI on shut down.
No change in threads as it screws on the 1/2" male threads and ends in 1/2" male threads.
This comes in play if you have a very large single zone and you need to keep the pressure high within all the PVC piping but bring it down before you get to your drip components connecting to the 1/2" riser.
When installing an irrigation system using PVC threaded fittings you should use two or three wraps of this teflon tape on the male ends. Not only does it help seal against any water leaks it allows for a smooth threading together of parts. Even better it lets you UNscrew parts if needed, now and in the future! If you think we are kidding try for yourself and test with and without................told you! :-)
