 New water heater now half my house hot
Author: PRinIndy (IN)

Replaced water heater in 15 year old house, only had to solder cold side copper. House is all pex after water heater. One hot line runs to manifold on opposite end and distributes to sinks and shower. I have a Laing circulating pump to keep water hot on that side that I turned off several years ago. I know get hot water on one side by water heater but other side takes awhile and then never gets as hot as closest side and it is not consistent. Thought it would be a simple switch out but now I am at a loss. Any thoughts?

I’m thinking bad check valve on the recirc line

What happens when you run the recirc pump?
