When most people set out to make their homes more energy-efficient, the focus is usually on insulation, upgraded windows, or smart thermostats. Your plumbing system, however, plays a surprisingly big role in conserving both energy and water, and updating it can deliver impressive savings on monthly utility bills while helping preserve valuable resources.
From tankless water heaters and low-flow fixtures to smart leak detection systems, energy-efficient plumbing upgrades not only help reduce waste, but they also extend the lifespan of your appliances and add long-term value to your home.
In fast-growing Montgomery County, where residents appreciate the benefits of comfort and sustainability, these practical improvements can deliver year-round benefits you’ll notice with every bill.
Ready to make your home more efficient? Below are some of the smartest plumbing upgrades that combine tried-and-true methods with innovative new technology, so you can enjoy lower costs and a greener footprint starting today.
The simplest upgrade you can make is still one of the most effective. Modern low-flow faucets, showerheads, and toilets deliver strong water pressure while using significantly less water than older models.
Benefits include:
Pro Tip: Choose WaterSense®-labeled fixtures to ensure EPA-tested efficiency without sacrificing performance.
Traditional tank water heaters keep 40–50 gallons of water hot around the clock, even when you’re not using it. That constant reheating wastes energy and drives up utility costs.
Tankless (on-demand) water heaters heat water only when you need it.
Advantages:
New for 2025: Hybrid models combine tankless efficiency with small storage buffers for instant hot water in larger homes.
If you run the tap for 30–60 seconds waiting for hot water, you’re literally pouring money down the drain.
A hot water recirculation system keeps hot water moving through your pipes so it’s available instantly at the tap.
Savings and benefits:
Pipe insulation is inexpensive, fast to install, and immediately effective.
How it helps:
Foam or fiberglass insulation sleeves are common choices, but professional installation ensures complete coverage and durability.
Homeowners that make this upgrade find that energy and water savings are modest compared to larger upgrades, but payback is quick.
If your dishwasher or washing machine is more than 10 years old, it’s likely costing you more in water and electricity than necessary.
Look for ENERGY STAR® models designed to conserve both:
Water leaks don’t just waste water — they waste the energy used to heat and pump that water.
Smart leak detectors monitor your plumbing for unexpected water flow and send alerts to your phone. Some models can even shut off your water supply automatically.
Why it matters:
Hard water can cause scale buildup inside pipes and appliances, making them less efficient. Modern energy-efficient water softeners use less salt, less water, and operate on demand instead of on a fixed schedule.
Today’s demand-initiated regeneration (DIR) softeners can reduce salt and water use by 20–50 percent less water, depending on hardness and usage.
Benefits:
Graywater systems capture gently used water from sinks, showers, and washing machines, then filter it for use in irrigation or toilet flushing.
TECQ in Texas defines graywater as “the wastewater from clothes-washing machines, showers, bathtubs, hand-washing lavatories, and sinks that are used for disposal of household or domestic products. Graywater does not include wastewater that has come in contact with toilet waste; or from the washing of material, including diapers, soiled with human excreta; or from sinks used for food preparation or disposal.”
Advantages of using graywater:
Important: Check with your local jurisdiction for rules regarding graywater usage.
Many homes have higher-than-necessary water pressure, which leads to wasted water and increased wear on plumbing fixtures. Installing a pressure-reducing valve (PRV) ensures your system runs at the optimal range — usually 50–60 PSI for homes.
Why it’s worth it:
While not directly part of your indoor plumbing, rainwater harvesting systems can work alongside your home’s plumbing to provide free, eco-friendly water for irrigation, washing vehicles, or other outdoor uses.
Key benefits:
Not every homeowner needs all of these upgrades right away. Many start small — replacing a showerhead, insulating pipes — and work up to bigger changes like a tankless water heater or graywater system.
