Q. Recently, you mentioned "hot-water recirculating" systems for home use, when people have to wait a long time for their shower water to get hot. I have used this type of hot-water system with success in the shower, but now have trouble getting our normal cold water from the kitchen-sink faucet. Since we do like the faster hot water to the shower, any suggestions on improving the kitchen-sink cold-water issue?
A. Recirculating systems can get hot water quickly to your shower, but need to be installed as per local codes with any necessary permits taken out. Because most domestic hot-water recirculating pumps use a home's existing cold-water lines as a return back to the water heater, it's important that you work with a licensed master plumber on any crossover issues.

A plumber will check if pumps and controls are set and installed properly, if the system is running as per the manufacturer's instructions and if any cold-water lines feeding your kitchen sink need to be moved to help improve the system.
Bottom line: If your body has circulation issues, it's best to call a doctor. For your home's circulation issues, it's best to call a master plumber!
