How to Lower Your Water Bill in Montgomery County: 9 Plumbing Tweaks That Work

How to Lower Your Water Bill in Montgomery County: 9 Plumbing Tweaks That Work

If you live in Gaithersburg, Rockville, or Germantown, you have likely noticed that water isn’t getting any cheaper. For many homeowners in Montgomery County, opening the quarterly WSSC Water bill can be a stressful experience. High usage charges, infrastructure fees, and “tier jumps” can turn a standard utility bill into a budget-busting expense.

The good news? You don’t have to take cold showers or let your lawn die to save money. Often, the culprit isn’t how much water you are using, but how much your plumbing system is wasting. As local experts serving the 20878 area and beyond, we see hundreds of homes losing money daily due to inefficiencies that are easy to fix.

Here are 9 professional plumbing tweaks that will help you lower your water bill, protect your home from damage, and improve your system’s efficiency.

1. Check Your Water Pressure (and Install a PRV)

1. Check Your Water Pressure (and Install a PRV)

High water pressure might feel nice in the shower, but it is a silent killer for your plumbing and your wallet. In many parts of North Potomac and Darnestown, municipal water pressure can exceed 80 psi. This forces more water through your fixtures than necessary every time you turn on a tap.

The Tweak: Have a professional test your water pressure. If it consistently reads above 60-70 psi, install a Pressure Reducing Valve (PRV). This device regulates the flow coming into your home, reducing waste and protecting your pipes from stress that leads to bursts. If you suspect your main line is under too much stress, our Water Line Repair team can inspect your incoming service and PRV.

2. Upgrade to a Hot Water Recirculation Pump

2. Upgrade to a Hot Water Recirculation Pump

How long do you let the shower run while waiting for it to get hot? In larger homes in Potomac or Kentlands, that wait can waste gallons of clean water down the drain every single morning.

The Tweak: Install a hot water recirculation pump. This system keeps hot water moving through your pipes so it is available instantly at the tap. It’s a game-changer for comfort and conservation. For installation options, check our Water Heater Services.

3. Fix the “Silent” Toilet Leaks

3. Fix the "Silent" Toilet Leaks

A running toilet is obvious, but a silent leak can waste up to 200 gallons a day without you hearing a sound. This usually happens when the flapper valve inside the tank wears out, allowing water to trickle continuously into the bowl.

The Tweak: Perform the “Dye Test.” Drop a dye tablet or a few drops of food coloring into the toilet tank. Wait 15 minutes without flushing. If color appears in the bowl, you have a leak. Replacing the flapper is a quick fix that stops this phantom expense immediately.

4. Switch to WaterSense Fixtures

4. Switch to WaterSense Fixtures

If your home in Montgomery Village was built before 1994, you likely have toilets that use 3.5 to 7 gallons per flush (gpf). Modern WaterSense toilets use 1.28 gpf or less. The math is simple: for a family of four, this swap can save thousands of gallons a year.

The Tweak: Retrofit your bathrooms with low-flow toilets and WaterSense showerheads. Modern technology ensures you still get a strong flush and good pressure, but with a fraction of the water usage.

5. Install Faucet Aerators

5. Install Faucet Aerators

This is one of the cheapest and most effective tweaks you can make. An aerator mixes air with the water stream, maintaining high pressure while reducing the actual volume of water flowing through the faucet.

The Tweak: Check the faucets in your bathroom and kitchen. If they don’t have aerators, or if the existing ones are clogged with calcium buildup (common with hard water in our area), replace them. It’s a small hardware change that pays for itself in the first month.

6. Address Hidden Sewer Line Issues

6. Address Hidden Sewer Line Issues

Sometimes a high water bill correlates with sewer issues, especially if leaks or blockages are causing your system to work inefficiently or back up. While sewer leaks don’t always directly increase the water meter reading (unless it’s a supply line), they signal an aging system that may be prone to supply-side failures too.

The Tweak: If you notice soggy spots in your yard or sluggish drains, schedule a Video Camera Sewer Inspection. Identifying root intrusion or cracks early can prevent massive waste and expensive emergency repairs later.

7. Insulate Your Hot Water Pipes

7. Insulate Your Hot Water Pipes

Heat loss from exposed pipes in your basement or crawl space means your water heater has to work harder, and you have to run the tap longer to get hot water to the second floor.

The Tweak: Insulate accessible hot water pipes with foam pipe insulation. This keeps the water hotter for longer as it travels to your fixtures, reducing the “warm-up” time and the amount of water you waste waiting for it.

8. Seasonal Maintenance on Outdoor Faucets

8. Seasonal Maintenance on Outdoor Faucets

A dripping hose bib (outdoor faucet) can go unnoticed for weeks, especially if it’s on the side of the house you rarely visit. In winter, these can freeze and crack, leading to massive leaks when you turn them on in spring.

The Tweak: Install frost-free hose bibs and check them regularly for drips. If you have an irrigation system, ensure it is winterized correctly to prevent underground leaks that spin your meter without you knowing.

9. Verify Your Water Meter

9. Verify Your Water Meter

Sometimes, the issue isn’t inside the house—it’s underground. A leak in the main service line between the street and your house is the homeowner’s responsibility in Montgomery County and can result in astronomical bills.

The Tweak: Turn off all water inside the house (make sure no toilets are running and the ice maker is off). Go out to your water meter box. If the small triangle or leak indicator dial is moving, you have a leak in your service line. This requires immediate professional attention. Contact us for Water Line Repair to stop the waste before it undermines your foundation.
