I had to replace the 1/2″ schedule 80 pvc elbow with a metal street elbow today, because of a small leak. I am going to replace the solenoid later so I did not replace all the pvc for now. I guess the weep solenoid (sprinkler system solenoid) may have worn out the pvc (from cutting on and off) and caused a small crack.
I also installed the last Flojet pump. Now I just need to put the last 2 Flojet pumps online.
