How long should a recirculating pump run?
Many recirculating pumps come with timers so that you can set them to circulate the water before you get up in the morning, leaving them off during the day, and the back on in the evening. Typical settings will leave the pump on for about 6 hours a day.
Is it safe to pour boiling water down drain?
Do NOT pour boiling water down your sink or toilet. While it’s probably okay to dump boiling water in the sink when your pipes are clear, a clog will trap the water in the pipe. This can melt PVC piping and pipe seals, causing serious damage.
When to install a gravity hot water recirculation loop?
It is recommended that recirculation loops be installed during the building phase of a house or building, to ensure efficiency in the plumbing design. The system also works best in multi-level houses or facilities, where the water heater is located at the bottom of the piping system.
What are the different types of hot water recirculation?
There are two types of hot water recirculation used in residential homes, which are: Gravity recirculation and Forced recirculation. Gravity hot water recirculation works on the basic physical principal that heated water weighs less per unit of volume than cold water.
Is it worth installing a hot water recirculation line?
Installing a hot water recirculation line is quite simple and relatively low cost but is most practical when planned into the design rather than a retrofit; as some systems, such as a home run system don’t lend themselves well to recirculation.
How to install a gravity hot water system?
Cut into the pipe at this location where the pipe in the basement turns up to go into the fixture on the first floor. Install a tee fitting in place of the 90-degree fitting. One part of the tee will allow you to reconnect to the hot water line. The other portion of the tee fitting will be the start of the return loop back to the water heater.

How does a gravity hot water system work?
Heat Rises. Gravity hot water loops work because the heated water, which is lighter, rises through the loop. As the water cools at the top of the loop, it falls and is thermo-syphoned back into the hot water heater. The water enters the bottom of the heater at the drain valve inlet.
