Hi Guys,
We bought a house a couple months ago. It has a sprinkler system installed and the main water supply is in the crawl space. Where the water exits the house, they have a u-shaped assembly of pvc pipe. Two days ago, I cracked this pipe with the weed eater and had to shut off the water supply.
My questions are:
Does this look correct? If not, what would you suggest I do while I am repairing the crack?
Is the u-shaped assembly of PVC acting like a poor mans backflow device? I don't believe there is one installed in the system.
Should I add some sort of fitting to this assembly to aid in blowing out the system? How do you suppose they blew out the system in years past?
Thanks!
Dan
