Plumbing Tips When Buying A House

Buying a house is exciting and a little scary. Before you pick the final one, check out below tips to reduce future costs and concerns…

Questions to ask the owner / realtor

  • Is the water service provided by Charlotte Water, a third party, or is the property on a private well?
    • Is wastewater service also provided by Charlotte Water?
  • If the house was built more than 50 years ago, has the plumbing been replaced? If it hasn’t, that could cost thousands of dollars to replace.
  • Are there any utility easements under the property?
  • Is there a pressure-reducing valve on the water service line?
  • Where is the water meter?
    • If the water meter is between the street and a sidewalk, and the private plumbing service line needs to be replaced, any damage to a sidewalk will be up to the property owner to pay.

Easements

CLTWater easements are not typically reported as part of a title search for title insurance when purchasing a property. Surveying the property is the best way to determine if there are any easements on it.​ Learn more at https://cltwaterblog.org/2023/03/easement-101/.

Low Water Pressure

If the property is at the top of a hill or on the highest part of the neighborhood, it is likely you will experience lower water pressure than others in the neighborhood. Learn more about other possible factors at charlottewater.org.

High Water Pressure

If the property is located beside a creek, at the bottom of a hill, or in the lowest part of the neighborhood, it may have higher water pressure than other properties in the neighborhood. Learn more about other possible factors at charlottewater.org.

Pressure Reducing Valve (PRV)

If the house is located in a geographically low area (near a creek) or near a water pumping facility, the water pressure may exceed 80 psi. Learn more at charlottewater.org.

Irrigation and Backflow Prevention Device Testing

If the house has an irrigation system, it probably also has a backflow prevention device that requires testing. 

Wastewater Cleanout

Most homes also have a white plastic lid, commonly referred to as a cleanout. This provides access to the wastewater pipe between your house and the public wastewater system, allowing you to inspect and clear blockages. Many houses do not have a cleanout and may be worth considering, especially if you have trees in the front yard.

Backwater Valve

A plumbing fixture called a backwater valve can prevent sewage backups. The North Carolina State Plumbing Code has required backwater valves in some homes since the early 1930s. If your plumbing fixtures are located below the top of the first upstream manhole, state regulations require the installation of a backwater valve. To determine if your property has a backwater valve or needs one, please consult a professional plumber or contractor. Learn more about other possible wastewater issues at charlottewater.org.


Waterfront Properties and Homes Lower Than The Public Street

If your future home is on waterfront property or the public road is higher than your house, the house may have a low-pressure sanitary sewer system to pump your wastewater up to the gravity-fed sewer system. Make sure you understand how old the pump is and if there have been any issues with the system. If you choose to purchase the home, consider having a plumber inspect it occasionally.

Read Inspector Notes

Consider getting a home inspector to investigate the house. When reviewing the inspector’s notes, pay close attention to any remarks related to the plumbing system. The inspector may provide details about the pipe type and age, potential water or wastewater issues, and the presence of easements affecting the property. Do any of the noted issues need immediate repair?

When reading the home inspection report, you may see information about water flow in gallons per minute (gpm) or water pressure in pounds per square inch (psi). The minimum expected levels at the water meter are

  • Flow is equal to or greater than 8 gpm
  • Pressure is equal to or greater than 20 psi
  • If the house numbers are lower than these, please consult with the inspector on readings. Backflow prevention devices, pressure-reducing valves, whole-house filtration systems, and other attachments to the plumbing system may restrict flow or pressure inside a home.

Cautionary Tale: Replace Old Water Service Line Before It Becomes an Emergency.

How CLTWater Repairs Leaks Under Highways, Interstates

To serve customers, CLTWater has water pipes under most roads, including crossing under highways and interstates.

So what happens when there is a leak or a necessary repair under a highway or interstate?

It starts with a lot of planning and preparation.

Teams of engineers and crews investigate the scope of the repair and begin working with the Charlotte Department of Transportation (CDOT) and the North Carolina Department of Transportation (NCDOT) to minimize impact on drivers.

Example: In the fall of 2024, crews installing a new pipe under Interstate 85 found excessive water entering the tunneling pits. Investigations revealed two underground leaks and cracked asphalt, which showed signs of water damage.

  • The team worked on an emergency plan.
  • At least one lane was closed on the interstate from 9:00 pm until 6:00 am Monday through Friday for at least a month.
  • Ground-penetrating radar (GPR) scans of each lane of the interstate helped identify the location of leaks and voids under the asphalt.
  • Stabilizing foam was injected under multiple lanes. More than 600, ¾ inch diameter holes were bored and injected to stabilize the subsurface.
  • The pipes were investigated from the inside using robot cameras. The pipes were in good condition, but some seals needed to be temporarily installed to keep them in service.
  • New pipes were installed inside the existing pipes to maintain use and minimize leaks.

Plumbing Nightmares! ! Mistakes Were Made & How to Prevent Them

Owning a home is scary these days. And your plumbing is haunting you from under your floors. So, grab a cozy blanket and join us as we explore the spooky side of home maintenance.

The wrong turn and water rushes everywhere.

It was Thanksgiving night, and the dishwasher wouldn’t start. I went under the sink, and there were three water valves: one for the faucet, one for the dishwasher, and one for the refrigerator ice maker. I traced the water lines to where they appeared to go and made an educated guess to turn off the water valve close to the dishwasher so I could try to repair it. I was wrong. I accidentally turned off the ice maker. I realized it as soon as water gushed all over the floor. Make sure to put a tag or identifier on your plumbing valves, and if doing work on an appliance, make sure to turn off the right valve or the master shut-off valve.

Cockroaches will wake you in the middle of the night if you rarely flush a toilet or floor drain.

The house had a small bathroom that wasn’t useful, so it wasn’t used, for several months… The water in the toilet evaporated and cockroaches found a new home. The cockroaches made a huge mess, and the toilet’s wax seal dried out, requiring a replacement. Set a reminder to pour a little water down drains or flush occasionally.

The Sourdough Monster that Broke the Dishwasher

So many people are enjoying the benefits of making their own sourdough recipes. Until the sourdough starter goes down the drain and forms a giant clog. Sourdough starter can harden in your pipes or your dishwasher, leading to costly repairs and replacements. Always scoop your discard into the trash to be safe.

Not cleaning your dishwasher filter will lead to a Ghoulish Gunk

Why is there a puddle and thick pink goo in the bottom of the dishwasher? It is easy to forget that your dishwasher has a filter and that it may need cleaning occasionally. Ignoring the filter will eventually lead to a nasty, smelly clog. Check with your owner’s manual on when and how to clean it.

The Noise is coming from inside the house!

Our son was home alone and called in a panic. There is someone upstairs! I heard them walking around and stopping for a bit, and then walking around again. My son’s brilliant decision was to grab a knife and attack the intruder. I persuaded him to stay where he was until I could get back. We could hear the walking sounds, and then it stopped. But it wasn’t an intruder, it was the washing machine wobbling and banging the wall. Make sure your loads are not too overloaded and that there is adequate space from the walls.

The trees are rooting for you!

Sure, the water drained slowly for a while, but that’s not a problem, right? I was running the laundry and the dishwasher, and all was fine until I heard a waterfall from the bathrooms. I tried the plunger and put towels on the floor to mop the water off the floor, but the water kept pouring out of the toilets. It was the tree roots that clogged my sewer drain and what made it worse was not realizing that the appliances were sending water down the drain only to pop up in the bathrooms.

Know where your sewer line exits your home and see if you have a cleanout. If you don’t have a cleanout, talk to a plumber about whether you may need one. Look at trees near your sewer line. If you experience frequent slow drains, consult with a plumber about possible solutions.

The drain cleaner ate my plumbing

You get busy and forget what you are doing until what you forgot costs $$$. Pouring drain cleaner chemicals down your drain to clear clogs can also damage your plumbing if done often, left in the plumbing without flushing it out on time, or if the directions are not followed correctly. The chemicals can weaken you pipes and seals. Know your pipe material and follow instructions precisely (set a timer). Consider alternatives to clearing a clog.

Drip drip drip from the attic

You hear a drip, a drip, another drip, a puddle. Oh, great. We have a roof leak in the rain, or is it something else? Don’t wait for the rain to stop; look in the attic. Scary place, I know, but your home has a sewer vent to help ghastly odors escape. If you have an old house, your sewer vent may be the source of the leak, either through corrosion of the pipe or where it comes through the roof.

The mail doesn’t come on Sundays?

The toilet was clogged, and we couldn’t get it to flush anymore. Finally, we called a plumber and they pulled out the blockage of envelopes. Yes, a previous renter clogged the toilet with the open envelopes from the mail.

Only toilet paper goes in the toilet. Everything else is trash or recycling.

Hear a noise, see a damp spot?

Don’t be scared. If you see water where it shouldn’t be, grab your flashlight and start investigating like Scooby Doo and the Mystery Gang.

Minimizing Water Disruptions To Customers: An Emergency Repair on IBM Drive

In July 2025, Charlotte Water faced a significant emergency repair on a water main running along IBM Drive, an essential roadway servicing both commercial and residential areas. The section of the line required urgent repair, but the stakes were high. A complete shutdown would have resulted in water loss for two sizeable businesses as well as a large neighborhood.

The risk of widespread service disruption posed serious consequences for local commerce and daily life. Charlotte Water needed a solution that would allow it to isolate the repair site without interrupting service to its key customers, and our staff rose to the occasion.

“We were able to complete the repair quickly and efficiently without disrupting service to our commercial or residential customers,” said Jason Bromirski, a senior engineer at Charlotte Water. “This is an ideal outcome for such a critical location.”

To maintain service while addressing the damaged main, Charlotte Water installed an insta-valve. The insta-valve can be installed on an existing in-service main and allows us to perform maintenance or repairs without shutting down nearby blocks of the water distribution system.

Some problems require creative solutions, and Charlotte Water works every day to keep our water safe, reliable and flowing to your homes and businesses.
