Water Heaters
Hot water recirculation pumps
A recirculation pump keeps hot water close to the fixtures so it arrives in seconds instead of minutes. Homes without a return line can use a pump at the water heater with a crossover valve under the farthest sink, and timers or on-demand buttons keep energy use down.

Sprawling single-story Valley floor plans put the master bath a long way from the garage water heater. Waiting a minute or more for hot water wastes water and patience.
Many newer homes have a dedicated return line already plumbed. Older homes can use a crossover-style system with no new piping.

Frequently asked questions
Does recirculation raise energy bills?
A pump that runs constantly can. A timer or on-demand control keeps the extra cost small.
Does it work with a tankless heater?
Some tankless models have built-in recirculation. Others need a compatible pump and settings.
