Swing joint question
Still planning;
Since I am near the low end of pressure to my heads (~25psi)after RPZ, Main and laterals,
I am in a pickle concerning which swing joints to order.
Choices are
1.Rainbird model TSJ-12075, 12in,3/4 X 3/4 mpt-psi loss = 1.5 psi @ 6GPM Cost = ~ 16.00$ each (WOW!!!!!)
2.Hunter swing joint, 12in,3/4 X 3/4 mpt =2.9psi loss @ 3GPM (1.50$ea)
3.Toro funny pipe, 12in with Two,3/4"mpt elbows = 0.52psi loss @ 3GPM
Don't know the Toro price yet?
Any suggestions? Are the Hunter swing joints that restrictive?
Thanks
