My problem was unusual in that I was getting hot water to every outlet in the house, but over the last few months hot water was becoming less and less available at the master shower. Within about three minutes the master shower water would go from hot to cool, to cold. I assumed it was a problem at that location, so I removed and replaced the Moen balancing spool, hoping that it was defective and the cause of the problem. To my disappointment, that (difficult) procedure did not bring the needed uninterrupted flow of hot water to my master shower.

The plumbing configuration in my house is somewhat complex and includes a recirculation pump that circulates hot water throughout the house as well as a pressure tank to control the water pressure going into my water heater.

I called Lloyd's Plumbing and technicians Ted and Richie analyzed the configuration. In just a few minutes they determined that a flow valve near the circulation pump was partially frozen and creating a vacuum that caused a backflow of cold water into the hot water line that flowed to the master shower (the farthest water outlet from the pump and water heater).

They replaced the flow valve in about a half an hour and the entire system works perfect now. It was a great relief to have unrestricted hot water back into my master shower.

The cost was reasonable; Ted and Richie were both professional and competent and I wouldn't hesitate to call Lloyds again for my plumbing needs.
