Wow, cold in Lexington S.C. today huh? If you have a lawn sprinkler irrigation system, Lexington S.C. you might want to have a look at the water main pipes, spigots and valves after this freeze thaws. You very well may have a broken PVC irrigation water pipe that needs to be repaired. PVC pipes crack and burst when the low temperatures sustain for more than a couple of days.
To repair a broken PVC pipe on your sprinkler system, you must first excavate all of the dirt from around the area. Often times this can be tedious because there are wires in the area and you don't want to bump your shovel into the pipe in another spot because if you do that it is likely the pipe will then be cracked in that spot as well.
You need to have plumbing expertise too. Sometimes, 90 degree elbows or slip t's can crack which would call for a repair to the pvc pipe junction. This calls for precise measurement, sometimes specialty repair parts, and skill that comes with practice.
After doing the repair, you need to purge the air from the system. Winterization of sprinkler systems in South Carolina is not always done, but if it has already been done you won't need to bleed the system until you do an irrigation start up in the spring. Nevertheless, if you do need to bleed the system, you will need to carefully open the backflow control valve and the bleeder valves on all zones to slowly let water back into the system and pressurize. If done incorrectly, the water hammer can cause even more headaches and broken pipes.
