every one knows the employees do not have to know how to use what they sell.I do not have a Home Depot, but I do have Lowes.I must be in there 2 or 3 times a day. I know who can answer my questions and who can't. The average shopper doesn't realize this. Now Jason, YOU ARE RIGHT. Even a restricted incomming line will finally become the same pressure as the water co. is pushing. Both you and I know how to go about this, but telling someone else is very hard to do. The only thing alse I can tell him is too check the fittings and incomming lines or to replace the tank. It's hard to recommend something without being there.This is why we have so many knowledgeable people on this forum submitting thier opinions. I only hope ,when he does find out what it is, he lets us know for the next one that has this problem. Talk to ya soon, Ron J.
