Hi, we moved to a house with valves leaking when the sprinklers are on. Is this normal? I also noticed that after the sprinklers are shut off the valves are still leaking with a lot of water and will stop after an hour. Do we need to replace them? The previous owner said that it was replaced 3 years ago. Also, I noticed that there is pipe that is directed at the back of the backyard that is letting the water drip out when the sprinklers are on? What is this for? Also, my husband repaired the pip...
