🚰 White, crusty buildup around your faucets?

⚙️ Well pump turning on and off constantly?

🔊 Water heater making strange noises?

Sound familiar?

⛈️ WELL, THAT WAS QUITE A STORM!

After weeks of dry weather & drought concerns across the DMV, Mother Nature certainly made up for lost time yesterday!

And while we needed the rain, a lot of water in a short amount of time can create some unexpected problems for your home's water system.

💧 WELLS & WELL PUMPS: Changing groundwater conditions can affect water levels, stir up sediment, and potentially impact water quality & pump performance.

🔧 WATER TREATMENT: Increased sediment & changes in water quality can mean clogged filters, cloudy water & a strain on your water filtration systems.

🏠 PLUMBING & DRAINAGE: Heavy rain can overwhelm sump pumps, expose drainage problems, and lead to basement flooding or backups.

OUR ADVICE? Keep an eye on your water over the next few days. Should you see any changes in pressure, color, odor, or taste please contact us!

And remember, just because the rain has stopped doesn't mean its effects on your water system have!

💧 FACT OR FICTION? THE TRUTH ABOUT WHAT'S IN YOUR WATER! 🚰

Think you know your water? You might be surprised! 🤔

Some of the things we've been told about water for years simply aren't true. From boiling water to bottled water, old plumbing, and even acidic water, there are plenty of misconceptions floating around!

We've been in the water business since 1979, and trust us, we've heard just about everything!

👀 Take a look at our blackboard! How many of these water myths did YOU believe?

💬 Let's have some fun: Which one surprised you the most? Or have you heard a water myth we missed?

At National Water Service, we believe understanding your water and your water wants & needs is just as important as treating it!

💧 LOW WATER PRESSURE? NO WATER?

Heavy Sediment & Iron Could Be the Problem!

If your shower doesn’t have the pressure it used to, your faucets are slowing down, or you’re constantly dealing with clogged filters & fixtures, don’t automatically blame your well pump.

Heavy sediment and iron in well water can build up throughout your water system and cause:

🔹 Low or reduced water pressure
🔹 Clogged faucets and shower heads
🔹 Rust-colored stains on sinks, tubs & toilets
🔹 Cloudy or discolored water
🔹 Frequent sediment filter changes
🔹 Buildup in plumbing and fixtures
🔹 Extra wear on water-using appliances

At National Water Service, we don’t just treat the symptom, we help determine what’s actually causing the problem & recommend the right solution for your family's water.

🚨 You Clean It. It Comes Back. What Is That Pink Slime?🚨

Have you ever noticed a pink or orange film that seems to show up around sinks, faucets, showers & toilets no matter how often you clean?

Commonly called “pink slime,” it’s typically a bacterial biofilm that thrives in warm, damp environments & can build up on surfaces around your home.

💧 Does it mean your water is unsafe?

Not necessarily. But when it keeps returning, it may be worth taking a closer look at your water quality, plumbing and water-treatment system.

That’s where National Water Service can help.

💧 INSTALLATION OF THE DAY — MONTGOMERY COUNTY, MARYLAND!

For this home, we installed:

⚙️ Pedrollo USA water booster pump
🦠 VIQUA Ultraviolet light for bacteria in water
🔹 Pre & post sediment filters
💦 Replumbed the existing water softener

🚨 WATER ALERT FOR MONTGOMERY & PRINCE GEORGE’S COUNTIES 🚨

A power outage at WSSC Water’s Potomac Water Filtration Plant is affecting the system that serves approximately 1.9 million customers.

💧 The good news: WSSC says the drinking water remains safe at this time, and there is currently NO boil water advisory.

⚠️ But WSSC is asking customers to conserve water immediately to help maintain system storage, preserve water for fire protection, and reduce the possibility of a boil water advisory.

If you’re on WSSC water, for now:

• Take shorter showers
• Avoid outdoor watering and irrigation
• Limit unnecessary toilet flushing
• Hold off on laundry and dishwashers when possible
• Turn faucets off as quickly as possible

The Potomac plant normally supplies drinking water to roughly 75% of WSSC customers, so conservation can make a real difference while crews work to restore power.

At National Water Service, we’ll continue watching the situation and sharing important updates that affect our local customers and their water.

💧 Please share this with friends and neighbors in Montgomery and Prince George’s counties.

WSSC Water is urging all customers in Montgomery and Prince George’s counties to use water only for essential purposes after a power outage.

💧 Ever wonder what happens before water reaches your faucet?

If your home is on a private well, there’s an entire system working behind the scenes every time you turn on the water.

🌧️ Rain and snow replenish the groundwater beneath us.
💧 Groundwater collects in underground aquifers.
⬆️ Your submersible well pump brings that water into your home.
🔵 Your pressure system keeps it flowing at the pressure you need.
⚙️ Water treatment can address problems like hardness, low pH, iron, sediment, odors and bacteria.
🚰 Then it’s delivered throughout your home; to your sinks, showers, appliances & more.

One glass of water. A lot happening behind the scenes.

And when something along that journey isn’t working properly,

National Water Service can help, from the well pump to the water treatment to the plumbing!

We’ve been helping homeowners understand and care for their water systems since 1979.
