"Honey, there's an awful lot of water in the basement". Darn, i hate to hear those words. Armed with a flashlight can't find any reason. Luckily we are club members with MoreVent. They were out in a flash, found the culprit (or at least the handiwork of the culprit) down the vent pipe. Alex cleared out the debris, ran the check light up and down the line and we are rockin'.
