Lukewarm water in upstairs shower - can I fix myself?
I have a 30 year old house with original faucets. I'm getting lukewarm water upstairs and hot water downstairs.
I thought it was the old hot water heater and had a new one installed last week, but the problem remains. I spent all my money on the water heater, so have no resources to hire a plumber.
The shower was nice and hot one day, then lukewarm the next, so it happened suddenly. The weather is very cold here and has been below zero.
Thanks for your help, I really appreciate it!
