I feel your pain. It's 6 pm and 91F, 33C. My weather station was over 100F today but it is out in the sun so it reads high. I bought a new Micro Rain MR25 traveling sprinkler to water the wife's riding arena to keep the dust down. Spent the day trying to get it going. Could not get it to work so I went to TSC and bought a boost pump. Pressure was high enough but still didn't work. Found out the inlet screen was plugged up. Cleaned it out and it worked great without the pump.
