cold water runs hot
 
When I turn on my cold water taps in bathroom sink or kitchen, the water runs hot for a very long time, finally cooling to lukewarm. I never get truly cold water. I can get cold water first thing in the morning, or late in the evening. What is a likely explanation/fix for this? This may be ridiculous, but is it possible that the Phoenix heat plays any part in this (108-115 in the summer)?

We live in a single story home, no basement, with PVC plumbing throughout.

You have a cross connection somewhere....


do you have one of these installed?

Check the dip tube in the water heater, it could be the problem.

How old is your home?

Do you have any type of circulation pump installed?

Has this just started?

My Bad, you said cold water.

Ok if you have Moen faucets in the house, it could be one of the cartridges gone bad, yea sounds odd, but I have encountered this a few times.
