1" or 3/4 " copper feed to RPZ
Is there much difference in a 1" copper feed from the meter, or a 3/4 in feed to the RPZ valve? Run is ~ 50 feet in the crawl space to outside RPZ,with 4- 45 degree and 2-90 degree copper fittings. Also, can I use galvanized unions for the RPZ valve, off of copper pipe? As mentioned pefore, I have 38-40 psi before RPZ valve.
Thanks

you can use 3/4" to the valve and then 1" sprinkler lines...... or you can do all 1" your choise...as far as unions you can run them off copper pipe.

Based on the pressure charts I have, a 50' run of 3/4" copper will lose about about 3psi of pressure while a 1" copper will lose about 0.75psi (assuming a flow rate of about 7gpm).
you are better off runnign all 1"
Thanks
