I made a morning run to Home Depot to get foam boards and a drill bit and more pipe hangers and a package of drippers. I came home and installed the last of the hangers which involved drilling another hole in the mortar. i tested the system with one dripper and quickly found a leak where the 2 pipes join together. The insert was too small of a diameter. I repaired this and got the dripper working then discovered the end of the tubing which is crimped is leaking. Libbie needed to go to Home Depot to get another plastic saucer so I took advantage of the trip to get a pipe plug for the leaking end and also to return the foam board. I only needed one foam board cut into 2 pieces to block the hatch to the crawl space and I bought two. The board cut up should work well. To assist with filling the voids i also sprayed some foam around the pipes and wires. I did another test of the water pipes and all seems better. We put one dripper into the corn plant on one run and two drippers into the ficus tree. One minute of time should put 5 cups of water out of each dripper. On the way back from Home Depot we stopped into Kroger and bought the ingredients for the Quick Taco Salad. Dinner was Taco Salad with Cabernet. I'm satisfied tonight that the waterers are done on the back porch and that the pain in my side has subsided. I was really worried by the pain but it was great to see that after 2 days of severe pain it has gotten down to a dull soreness. Good deal!
