How much water am I wasting waiting for hot water? A typical family can waste thousands of gallons of water per year waiting for hot water to reach distant fixtures. This waste increases your water and sewer bills while harming the environment. Principle Plumbing installs recirculation systems that eliminate this waste, helping we bring years of experience homeowners conserve water and lower their utility costs.
Will a recirculation pump increase my energy bill? Not with smart systems! By preventing you from running the tap for minutes at a time, you actually reduce the amount of hot water your heater needs to produce, which can lead to energy savings. Principle Plumbing installs Grundfos COMFORT systems with AutoAdapt technology that only circulates when you need it, keeping energy costs minimal.
Can I add a recirculation system to my existing water heater? Absolutely! Recirculation systems are compatible with both traditional tank and modern tankless water heaters. Principle Plumbing specializes in retrofitting existing we bring years of experience homes with these systems, using your existing cold water line as the return path—no need to run new pipes through your walls.
Do you have to run new plumbing for a recirculation system? No! That's the beauty of retrofit systems. No new pipes need to be run through your walls, making it ideal for existing homes in we bring years of experience. Principle Plumbing uses your existing cold water line as the return path, keeping installation clean, professional, and minimally invasive to your home.
How does a smart recirculation pump know when I need hot water? Modern systems with AutoAdapt technology learn your family's hot water usage patterns over time and operate only when needed, maximizing comfort while minimizing energy use. Principle Plumbing installs and programs Grundfos COMFORT systems to match your household's unique schedule for optimal performance.

Every time you turn off a hot water tap, water left sitting in your plumbing cools down. The next time you need hot water, you must run the faucet to push all cooled water out until hot water finally arrives from your heater—the longer the distance, the longer the wait and greater the waste.
A hot water recirculation system creates a loop that slowly and periodically circulates hot water from your heater back to fixtures, ensuring warm water is always in the pipes and available the moment you need it without running taps for minutes at a time.
The system consists of a small, quiet pump installed on the hot water line at your heater and a special sensor valve installed under the sink at the faucet furthest from the heater, using your existing cold water line as the return path with no new pipes needed through walls.
Experience instant comfort and convenience with hot water available at taps in seconds, massive water conservation saving thousands of gallons per year, potential energy savings by reducing hot water production, and compatibility with both traditional tank and modern tankless water heaters.

We proudly install the Grundfos COMFORT PM AutoAdapt Recirculation System featuring smart AutoAdapt technology that learns your family's usage patterns and only operates when anticipated, maximizing comfort while minimizing energy use with whisper-quiet operation using less energy than a 25-watt light bulb.
We identify the faucet furthest from your water heater as the ideal sensor valve location, safely install the Grundfos COMFORT pump on the hot water outlet pipe, and install the smart sensor valve under the sink connecting hot and cold supply lines to create the temporary loop.
After installation, we prime the system and set the pump to intelligent AutoAdapt mode, then test to ensure hot water arrives at your fixtures dramatically faster. These systems are virtually maintenance-free with self-lubricating pumps designed for years of trouble-free operation.
A professionally installed high-quality retrofit system like the Grundfos COMFORT typically costs between $900 and $1,500 in we bring years of experience. While the pump uses very little electricity, smart operation minimizes energy use and the cost is often offset by water and sewer savings every month.
