Report "I have a Shurflo Diaphram pump used for a spray rig for pest control. The pump is only about 4 months old. This morning it would not come on. We checked the switch and the power source and all is good. We bypassed the switch and it still would not come on. We don't know what to check next. There was a freeze this past weekend. We don't see any visible damage to the pump or pipes. Do you think something froze in the pump?"
