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.

Mount Holly Pump Station Officially Commissioned

Charlotte Water and the City of Mount Holly celebrated the official commissioning of the Mount Holly Pump Station at Tuckaseege Park. This transformative moment reinforces our commitment to providing the best regional water infrastructure for our community.

Connecting Communities

This commissioning ceremony represents more than just flipping a switch; it’s the culmination of extensive regional collaboration and engineering innovation. The new pump station now connects Mount Holly’s wastewater system to Charlotte Water’s regional network through specially installed pipelines running approximately 65 feet beneath the Catawba River and Long Creek.

How It Works

  • Wastewater travels from Mount Holly homes and businesses to the new Mount Holly Pump Station
  • The station then pumps wastewater through underwater pipelines to Charlotte Water’s Long Creek Pump Station
  • From there, wastewater will be treated at existing Charlotte Water facilities

Partnership for the Future

This commissioning is a huge milestone in the larger Stowe Regional Water Resource Recovery Facility project. By transitioning Mount Holly’s wastewater service to Charlotte Water, we’re creating a more resilient and sustainable system that will protect water quality in the Catawba River while preparing our communities for future growth.

We extend our gratitude to everyone who joined us for this historic celebration. This achievement represents true connection across communities, demonstrating what’s possible when we work together to protect our water resources for generations to come.

Unlocking a New Level of Progress with a Plant: Nuvoda Pilot

Are small plant pieces key to a new level of greatness in the Queen City’s wastewater treatment process? Charlotte Water’s Sugar Creek Water Resource Recovery Facility (WRRF) has set out on a 12-month mission to learn.

Kenaf sample in an Imhoff Cone, the tool used to check how much kenaf is currently in Sugar Creek WRRF’s basins.

Nuvoda, a wastewater solutions company in Raleigh, NC, created the Mobile Organic Biofilm (MOB™) Process. The star of the show called kenaf is a fast-growing plant that can get rid of up to 10 tons of carbon dioxide per acre while growing. That’s eight times as much as evergreen trees! 

So, how does it work? Small pieces of kenaf are in all stages of Sugar Creek’s secondary treatment process. Its job is to help make space for helpful biofilms to grow.

Biofilms, a slime-like layer found in nature, grow on surfaces to eat the “waste” in wastewater and help solids settle faster.  This leads to treated water that can be safely returned to the environment.

The kenaf material is also reusable! A giant sift-like tool separates kenaf from the water. Screens inside of the filter are small enough to catch and make sure no kenaf is wasted or left to come out in your kitchen sink. Sugar Creek’s maintenance team even added some helpful features, like a ramp for it to fall out of the sift, into the bin below.

MOB and kenaf have other perks, too.

Chemicals like ammonia have to be controlled carefully while treating wastewater. The microorganisms needed to treat ammonia can be hard to grow in cold temperatures, but biofilms can provide a cozy space for these specialists to grow. Kenaf boosts the amount of space for the biofilms.

Treatment facilities need to run as smoothly as possible during storms. Improved settling thanks to the kenaf can help with higher water flows during rainy days. So, as the extra water comes into the plant from bad weather, solids settle faster and there is a lower chance of anything unwanted continuing to the next treatment stage.

Kenaf is grown in Cameron, NC, and Charlotte Water is working to include these fields in our biosolids program. Biosolids are a nutrient-rich material made from treated wastewater, used to help plant growth and keep a healthy environment.

The Nuvoda MOB pilot is a chance for Charlotte Water to improve for the future by lowering costs and getting ready for the city to grow. By exploring this new process, Sugar Creek WRRF is gathering useful data to help make decisions for improvements. All thanks to a plant!

Microplastics Reduction Researched at Charlotte Water

Jordan Landis taking a sample at the Irwin Creek Wastewater Treatment Plant.

Charlotte Water (CLTWater) is using sophisticated equipment to monitor water quality, and yes even wastewater quality, to look for emerging contaminants like microplastics.


Microplastics are defined as plastic materials less than 5 millimeters in size. They can be seen without the use of a microscope. However, nanoplastics are an emerging topic because of the need for powerful microscopes to observe and quantify them. Microplastics shed from plastic products and end up flushed down the drain to wastewater treatment plants and eventually into creeks. Even washing clothes will break down polyester and spandex materials and flush the microplastics into wastewater plants.

CLTWater sponsored an internship program to research microplastics and possible ways to reduce their impacts before the treated water enters creeks. Jordan Landis, a Charlotte Water intern and PhD student at the University of Michigan, studied the presence of microplastics in wastewater under the direction of Muriel Steele, a Charlotte Water Wastewater Process Engineer, and tested possible ways to use certain algae to help break the plastics down and remove them.

The original scope of the project was to bioengineer an algae species that would be able to excrete an enzyme that could break down PET-type plastics. However, the scope of this research has shifted to using the original bacteria species that was found to naturally excrete this plastic-degrading enzyme (the enzyme gene from this bacteria was placed into the algae) and culture that to break down plastics. Macroalgae species are proposed to be used to help capture the plastics to keep them in the system during the treatment process while the bacteria can eat the plastics off the algae.

During the testing process, Ms. Landis was unable to obtain the preferred bioengineered algae species and decided to use the wild-type strain of the bioengineered algae.

Ms. Landis cultured the wild-type algae in CLTWater wastewater to understand the growth behaviors and nutrient uptake of the algae species. This knowledge will help optimize the bioreactor design with the algae before introducing plastics.

The preliminary results were more qualitative in nature, examining how well the algae would grow. Originally an algae-growing salt solution was used to jumpstart our cultures, but it was found that the wastewater was more effective.

In the future, the next step is to develop microplastic quantification methods at Charlotte Water that will help efficiently derive microplastic removal data from bioreactor studies. After this, the bacteria found to excrete the plastic-degrading enzyme naturally will be studied in CLTWater wastewater to understand its metabolic behavior and growth response to the wastewater growth medium.
