I have a huge problem. The cold water in the house when you turn it on, run really warm instead of cold. I have had 2 different plumbers look at the problem. One says there isn't anything to do as the pipes are in the attic and its really hot up there. (we are in AZ). The second says he can run a pipe from one side of the yard to the other and then tear up my walls in the garage to put a line in the ground to get it a little cooler. Is there any other options I should look at? I really hate to dig up the whole yard and house. Thanks!:confused:

When you turn on your cold how long does it run and stay hot? Have you insulated the pipes?

The pipes are not insulated as the plumber said it would make them hotter and it runs like that for a long time. The cold and hot water lines were also checked to ensure they were not mixed up
