Hi everyone! I just joined the forum this morning, hoping y’all can help us with our current quandary. We have a forty thousand gallon in-ground pool. Yesterday we noticed some standing water at the edge of our driveway out front. We’re in Phoenix’s west valley so any standing water is noticeable and/or unusual. The water is coming from a non-pressurized pvc drain line buried just a couple of inches down at the edge of our property. It appears to angle under our driveway. My husband assumes it is the overflow drain line from the pool and immediately suspected a problem with our autofill. We temporarily wedged a shim in the float basket to prevent the float from sensing a drop in water level. 14 hours later the pipe out front is still flowing. If the autofill were the culprit, wouldn’t the pool just overflow?? Any ideas??? We also have a sprinkler system but I don’t see why a sprinkler system would need a drain line but I admittedly know nothing about sprinklers. Regardless, something is leaking/draining. Thanks in advance for your help!!
