Imagine turning on your kitchen faucet only to notice the water smells off or tastes metallic. Maybe your family’s been experiencing frequent stomach issues or dry, itchy skin. What if your water is the culprit?

Clean drinking water is something many Texas homeowners take for granted until something goes wrong. Between aging pipes, agricultural runoff, and industrial waste, water contaminants are more common than you think.

If you’ve never had water quality testing done or considered installing a home water filtration system, now is the time. Let’s walk through what you need to know to protect your family and your plumbing.

What are the most common water contaminants in Texas?

Texas water often contains heavy metals, chemicals, and microbes.
Municipal water systems serve many homes in Texas, but that doesn’t mean your water is always clean. Water can pick up contaminants as it travels through pipes, soil, and old plumbing.

Common Water Contaminants by Type

Type

Examples

Health Concerns

Microbial

E. coli, Giardia

Diarrhea, nausea, vomiting

Chemical

Chlorine, pesticides

Organ damage, cancer risk

Heavy Metals

Lead, arsenic

Neurological damage, developmental issues

Minerals

Iron, manganese

Staining, taste, and plumbing damage

 

These pollutants can come from natural sources, industrial waste, or outdated infrastructure. Even well water can contain harmful levels of bacteria or nitrates.

How do contaminants enter your home water?

Contaminants can enter through pipes, groundwater, or treatment errors.
Even if water leaves the plant clean, it may not stay that way by the time it reaches your tap.

Pathways for Contamination

The longer water travels, the more exposure it has to contaminants. That’s why many Texas homes need a water filter for house use, not just for taste but for safety.

How can water quality testing help?

Testing tells you what’s in your water so you can treat it properly.
Before choosing a water filtration system, it’s smart to test your water. This helps identify specific issues like bacteria, nitrates, or lead.

What Does Water Quality Testing Measure?

You can contact OnPoint Plumber water services for reliable water testing. Our technicians help homeowners understand results and choose the right purification solution.

What kind of home water filtration system do I need?

The best water filter depends on what contaminants you have.
There’s no one-size-fits-all solution. The right water purification system depends on your water source and test results.

What are the health effects of drinking contaminated water?

Contaminated water can cause short and long-term health problems.
The effects vary depending on the type and level of contamination. Children, seniors, and those with weakened immune systems face higher risks.

Potential Health Effects

  • Short-term: Diarrhea, nausea, vomiting, skin rashes
  • Long-term: Kidney issues, liver damage, cancer, developmental delays

Drinking unfiltered water over time can quietly impact your health without any obvious signs until it’s too late. That’s why water purification system installation is a smart move for your family’s safety.

What are the signs your home needs a water filter?

Bad taste, odors, or plumbing issues can signal a need for filtration.
Even if your water looks clear, it may not be clean. Here are signs something’s wrong.

Symptoms of Poor Water Quality

Any of these symptoms could mean it’s time to install a professional water purification system in Texas. Our team at OnPoint can help diagnose and solve the issue fast.

How does filtration protect your plumbing?

Filtration reduces buildup that damages pipes and appliances.
Contaminants don’t just harm your health; they also wear down your plumbing. Hard water minerals and chemicals can corrode pipes and reduce the lifespan of appliances.

Benefits of Installing a Filtration System

A proper water filtration system installation ensures your plumbing stays in good shape, saving you thousands over time.

I have had two major jobs (requiring digging and underground work) done by On Point in the past two months. Both crews were extremely professional, gentlemanly even, and efficient hard workers. They go above and beyond to ensure customer satisfaction. On Point is my new go-to plumbing company. Would give them 6 stars if that was an option.

We did an addition to our home and used on point plumbing for all the plumbing. I wish there were more stars to give than only 5. The first day the owner of the company was under my house which is not an easy space to be in and took care of phase one. His employees that came and proceeded with phase two were very respectful and courteous. We also had a new born baby at this time and these guys made sure to be as quiet as possible but still were done quickly and did a great job! I will recommend them to anyone that needs any plumbing service.

Dakota and Daniel did an amazing job!!! They were very professional, respectful, and thoroughly answered any questions I had. They came in ready and got the job done in a very timely manner. I was going to use them over the weekend, but decided to wait until the weekday and without hesitation squeezed us in. This is the second time I have used this company and will use them in the future!!

I was referred to On Point Plumbing by someone I trust, but I'm always cautious because you never know until you use the service yourself. I could not have been more pleased with the professionalism and expertise of the On Point Plumbing staff. Starting with Aubrey in the front office; Aubrey is the perfect first contact for ANY home service company. She always picked up the phone, and the one time I went to voicemail, she called me back within minutes. The scheduling and times she gave me were followed up with almost exact precision. And, just as promised, the technicians called 30 minutes before arrival. (And they were here on time.) I knew within minutes of talking to Red and Trevor that they knew exactly what they were doing. We had a quick discussion about the problem and they went to work on it right away. They also communicated with me during the process so there were no surprises! Red and Trevor are experts and it shows. They cut out the leaking pipe section so I could see exactly what was going on, they explained the solution and told me what the end result would be. Trevor gave me a complete update on the condition of the other plumbing under the house, with pictures. Red answered all my questions about my current issue and future house re-plumbing if needed. Red even offered financing possibilities. I could not be more pleased with my entire experience with On Point Plumbing. Their professionalism would be the envy of any other home service company. Their customer service from top to bottom is one to emulate. Last, but not least, their pricing was very fair and reasonable. They're worth every penny! Thanks again for your service and I look forward to doing business with you again in the future.

My experience has been great! On Point went above and beyond to get my water heater repaired. If you live in a remote area like Comanche, TX and have a Home Warranty Provider (HWP), you will understand there are some repairs the HWP can not find Pro Contractors to provide repairs. If you can labor through the HWP process, you will eventually be authorized to find your own Pro Contractor, like On Point. While good, the HWP processed are frustrating and will require your Pro Contractor to call the HWP for authorization. This process along with HWP payment delays is a reason many Pro Contractors choose not to work with a HWP. When I found On Point, they listened to my problem and offered to call the HWP, providing the details needed for repair authorization (detailed information on code upgrades and labor estimates). Once I got confirmation from the HWP for authorization to pay the replacement, I gave On Point approval to proceed. On Point replaced the water heater that same day! All is good and my experience a memorable one! On Point gets a 5+.

I had a fantastic experience with On Point Plumbing when they came out to fix a bathtub leak in my Brownwood, TX home. The team was incredibly professional, arriving on time and fully prepared. They quickly diagnosed the problem and explained the necessary repairs in a clear and understandable way to someone that does not know anything about plumbing. The work was completed efficiently and with great attention to detail. I'm thrilled with the results and would highly recommend On Point Plumbing to anyone in need of reliable and professional plumbing services. Top-notch work, thank you
