Discolored water is a common plumbing problem that often scares people. But let me give you a reason to breathe a sigh of relief: Just because your tap water isn’t clear, doesn’t mean that it’s harmful. However, it does mean that something is wrong with the domestic water system.

(And remember, lead in your water supply IS harmful!)

It’s important for all adults to take notice of our tap water’s color, smell and taste, as well as other details of our water pipe systems, especially if you own your home.

So if not all discolored water is dangerous, what does the discolored water mean? And how can you tell if your water is dangerous for consumption? We break it down for you:




Yellow or Semi-Red Water – If your tap water is clear at first but then changes to yellow or rusty color when it stands, then there is ferrous iron in the water, which means the iron that is leaching into the water has not rusted or oxidized yet. This is not harmful to our health, but note that this type of iron cannot be filtered out of your water.

Rusty Reddish Water– This color water means that ferric iron (oxidized iron, also known as rust) is leaching into your tap water. While this is not toxic, it is not easily filtered out and can stain sinks, bathtubs, etc.

Greenish Blue Water (dangerous) – If you’re seeing this color water, find out if your water pipes are copper or if you water system has brass fittings. If so, this water discoloration is a result of copper leaching and the water is dangerous for consumption. Please contact a plumbing company, like us, immediately. 

Green Water (dangerous)– Seeing green water means algae buildup has occurred in your plumbing system. Please contact a plumbing service company, like us, to correct the issue.

Black Water (could be dangerous)– This could be from manganese, which is harmless, or it could be from mold or mildew. Therefore, it’s best for you to call a plumbing company, like us, to check it out.

Pink Water – Your local water authority may have accidently added too much potassium permanganate to the water supply if the water looks pink. However, it is not harmful to human’s health.

Purple Water (dangerous)- A harmful amount of potassium permanganate was probably added to the water supply to cause it to turn purple. It’s best for you to inform the water authority about it immediately.

White or Cloudy Water– This mean extra air is trapped in or moving through the water. If you put some of the cloudy tap water into a glass. Bubbles should rise and the cloudiness should dissipate.

Clear Water (could be dangerous)– Lead does not have a taste or smell and it cannot always be seen in drinking water. That clear, clean-looking water coming out of your tap water may have dangerous levels of lead in it and the only way to know for sure is to have your tap water tested.


More info about Rusty Water:

Iron can get into the water supply due to iron being in the soil or if the pipe system contains iron. Iron in plumbing systems deteriorates over time due to the chemistry from the water and oxygen. The natural by-product of corroding iron is rust, which breaks off in the pipes and goes to the tap, causing the water to be discolored and usually revealing a rusty color. Keep in mind that the EPA says iron in water is not toxic and does not have a direct impact on health.



So now what?

If you’re located in southeast Texas, please give us a call or send us an email with your concerns or questions. We’d love to help!

Sometimes discolored water problems have easy fixes and sometimes they don’t. The best way to alleviate or prevent discolored water (as well as pinhole leaks, under slab leaks, low water pressure, bring lead leaching into compliance and other problems) is to protect your galvanized or copper water system with a safe (tested and certified to NSF Standard 61), internal pipe epoxy barrier coating. The patented ePIPE epoxy barrier coating is a cost-effective and better value alternative to a whole house repipe. Learn more about ePIPE by clicking here.

It is not intended to be used for diagnosing plumbing problems or whether one should drink or not drink the water.  Water discoloration is a symptom of something wrong with the pipes or water supply. We advise anyone who has discolored water at their home or place of work to contact a local plumbing company or TDT Plumbing for assistance and more information.

There is a special charm to older homes. The architecture, the story the house holds within its walls, beautiful original features, such as hardwood floors or a hand-carved staircase.

Old houses may be full of personality, but they’re also full of old plumbing. And it’s something to be mindful about.

If your house was built before the 1970s and still has the original plumbing – it’s just a matter of when your old plumbing will fail. (Also, since old plumbing is often made of galvanized pipes, usually the pipes won’t last this long, so there’s a good chance that at least part of the plumbing has already been replaced or rerouted.) Whether you have lived in your older home for decades or are considering purchasing an old house, it’s extremely important for you to be informed about old house plumbing problems so that you know what to symptoms to look for and how to handle them.



Old House Plumbing Problems:

Clogged galvanized pipes - If you’re experiencing rusty-looking water or low water pressure, these are common signs that your galvanized pipes have a lot of internal corrosion. Galvanized pipes are steel pipes covered with a layer of zinc, but the zinc slowly erodes. When corrosion and rust form inside the pipes, which naturally occurs with time, they block the flow of water to the tap, cause discoloration to the water and, even worse, leach toxic lead into the water.

Solution: We would most likely recommend a whole house ePIPE. ePIPE is a patented process that thoroughly cleans the pipe system and then applies a strong epoxy barrier coating inside the pipes to prevent the water from touching the pipes. This prevents corrosion, rust, lead leaching, leaks and other problems.


Clogged drains – It’s very common for older houses to have problems in the sewer line that runs from the house to the city main beneath the street. Over the years, this underground sewer line could have developed breaches or holes, which attracted nearby tree roots, causing root intrusion and blocking the line. More possibilities include the sewer line moving from the ground shifting or the line being crushed from roots growing on top of it, as well as the drain system getting plugged up from built-up grease, food or items that were not supposed to be discarded down the drain, such as a diaper. (There’s no telling what the previous owners flushed down those drains.)

Solution: Plumbing problems in old houses often include slow drains, but a camera inspection should be able to find the cause. If there is a small blockage that can be removed, it could be a quick and easy fix. But depending on the type of drain pipes, their layout and what lays above them, each individual case will have a unique solution. However, we highly recommend you get your drains hydro jetted around every two years to prevent blockages and slow drains.


Defective repairs made by previous homeowners or handymen – Over the years, your home probably had multiple owners. And maybe one of these homeowners decided to do a DIY fix-it project on the plumbing or maybe a homeowner had a handy cousin who made his own repairs. Some common problems could be pipes not connected properly, sink drains getting stopped up easily or a mistake could be more serious, such as a hot water heater being installed incorrectly.

Solution: Get the entire plumbing system looked at by a professional, like our team at TDT Plumbing. We understand the difference between efficient plumbing and troublesome plumbing, and can assess the system to predict if there will be future problems.


Leaks – Leaks are practically inevitable. All types of pipes can leak after so many years of use. Signs of domestic water, air conditioning or fire sprinkler pipes leaking include wet walls, wet floors, mold and increased water bills. Signs of a sewer pipe leaking are foul odors, wet spots on the floor or landscape and slow drains. As you can imagine, leaks are stressful, disruptive, destructive and expensive to deal with. The ideal situation is to invest in a long-term solution that will prevent the pipes from corroding on the inside and forming leaks.

Solution: Depending on the problem, fixes could range from a very small pipe replacement to a reroute or to a whole house pipe lining project to prevent the other pipes from failing (as an alternative to having all of the pipes ripped out of the house). A competent plumber will be able to analyze the situation and give you options depending on your budget and timeframe.


Old fixtures – Old fixtures in old plumbing can corrode with time and lose functionality, so they need to be replaced. Examples of fixtures include faucets, shower heads, angle stops, shut-off valves, supply lines to fixtures, and drain traps.

Solution: Hire an honest and trusted professional plumber, like TDT Plumbing, to examine your plumbing system’s fixtures and suggest which fixtures need to be replaced.


Lead service line – Houses and buildings constructed before the 1960s often have a lead service line running from the city’s water main beneath the road to your house. These lead service lines are notorious for leaching dangerous levels of lead into your tap water. You should err on the side of caution and have your water tested for lead (and other contaminants).

Solution: Lead service lines are dangerous to your family’s health. Instead of spending a small fortune to have your yard dug up, the service line pulled out and replaced, we highly recommend a whole house ePIPE. This is a patented process that thoroughly cleans the pipe system and then applies a strong epoxy barrier coating inside the pipes to prevent the water from touching the pipes, ultimately protecting your water from toxic levels of lead.


Weird or unsightly reroutes – You may notice signs of previous reroutes in your kitchen, laundry room or outside. Reroutes are often performed in place of a repipe, so that means that the pipe system was experiencing problems. 

Solution: If you don’t like the way a reroute looks or if you want to make sure the rest of the plumbing is working efficiently, and if you live in southeast Texas, please contact us. We can assess the reroute for a low fee and provide our professional advice about your options.



If you currently live or plan to live in an old house, make sure you’re educated about the home’s old plumbing. The types of pipes, where they’re located, how old they are, their diameters and the plumbing’s repair history are all important details to know.

We suggest you have the old plumbing inspected by a trusted plumbing team, such as TDT Plumbing, and have annual or biannual maintenance (such as cleaning the interior of the pipes) on all of the pipe systems within the house to ensure maximum efficiency and minimal probability of problems. We hope you utilize this advice or give us a call to prevent old house plumbing problems.

Does your home, building or property experience foul-smelling water, discolored water or low water pressure? If so, these are clear signs of internal corrosion and they could be bad for the health of the people drinking it, as well as the health of the pipe system.

Corroded pipes form when the water chemically reacts to the metal pipes (mostly galvanized pipes). Think of this process as the metal pipes slowly dissolving into the water, weakening the integrity of the pipe system and greatly inhibiting the pipe system’s functionality. Internal Corrosion is extremely common in pipes, but can result in serious consequences that are troublesome and expensive.

When left untreated, internal corrosion buildup in potable water piping will cause pinhole leaks, discolored water, foul-smelling water, distasteful water, poor water temperature transfer, low water pressure, and may cause pipes to burst.  These problems will worsen with time, but can be stopped and prevented with our state-of-the-art In-Place-Pipe repair solutions and prevention technologies.





TDT Plumbing’s Corroded Pipe Repair Solutions

Corroded Pipes Inspection: Using our diagnostic testing expertise, we will analyze the health of the potable water pipe system.

Corroded Pipes Repair: Our plumbing experts can apply an epoxy barrier coating to the corroded water pipes, replace the pipes or suggest other options to reduce the chances of this happening to the pipes again.

Corroded Pipes Prevention: Stop corrosion from forming by protecting the potable water pipes with a powerful, and completely safe epoxy barrier coating, called ePIPE (National Sanitation Foundation, NSF, tested and certified to Standard 61, meaning it is completely safe for use in all potable water applications). This special barrier coating prevents common water pipe problems.



It is important for you to know what type of water pipes your property has, the age of the pipes, the velocity of the water traveling through them and if the property has hard water or acidic water. These factors can help determine the longevity of a pipe system. However, a professional inspection and analysis by TDT Plumbing should be used to best predict future problems.

If you think your residential, commercial, industrial, educational or government building is experiencing pipe system problems due to internal corrosion, or other plumbing concerns, please give us a call immediately! We are proud to provide the most high-quality plumbing services with the fairest prices in the area, serving all types of properties and buildings in throughout Texas.

The saying goes: "Beauty is only skin deep."

This expression is used to explain that attractiveness does not equate to overall quality. While this idiom is mostly used in regards to people, it also should be kept in mind when analyzing buildings.

The message: You must always look beneath the surface, beyond the exterior, for a decent judgment of quality.

Even buildings with gorgeous architecture and manicured landscaping have plumbing problems riddled within the walls and below the foundation. It is not always a reflection on maintenance or caretaking of the property - many pipe system problems are inevitable, a direct result of specific water treatment chemicals or are a common sign of age.

If your multifamily property experiences chronic leaks, low water flow or discolored water, your property is not alone. These are very common problems that occur with age and use.

Fortunately, there is a cost-effective, non-invasive, long-term solution that can restore the pipe system without demolition of the property or relocation of the residents. But first, let’s discuss the different types of water system problems and why they occur.

Copper pipes commonly experience leaks. This is because the chemicals in treated, clean water can interact with the copper, causing corrosion and leading to pinhole leaks or slab leaks. Annoying, destructive and unpredictable, leaks can damage a home or cause mold growth within the building’s structure. Copper pipes also cause copper leaching (too much copper in one’s body can cause health problems.)

Galvanized steel pipes commonly experience discolored water, low flow and leaks. Over time, the water eats away at galvanized steel’s protective zinc coating and then interacts with the metal pipes, causing rust. This rust and residue build up to cause low flow and also cause discoloration or rusty-looking water. These types of pipes’ joints are known to easily corrode and leak. Galvanized steel pipes also cause lead leaching, which is extremely harmful to the health of all people, especially children and pregnant women.

Lead solder and fittings commonly cause dangerous lead leaching. Lead solder and fittings, often found in copper pipes, can still be found in buildings and homes constructed before the 1980s. Millions of American homes still have lead solder and fittings, which cause families to ingest lead at dangerous rates, causing mental and physical damage to the body.


As these types of chronic problems persist, whether they are leaks, discolored water, lead leaching or another issue, they become more frequent due to the increasingly deteriorating state of the pipes. Plagues of pinhole leaks are extremely common. Eventually, the HOA board or residential property management company searches to find an effective long-term solution, rather than hiring a plumber to repair each leak (consequently having to repair the walls, ceilings and floors inside the homes, as well), which is very inconvenient, time-consuming and costly.

The goal is to provide residents with a peace of mind that no more leaks will occur, without having to cause massive disruption, destruction or financial hardship to residents.

We are proud to offer the best solution for chronically failing water pipe systems for multifamily buildings and complexes.

This solution is ACE DuraFlo’s patented ePIPE pipe lining technology. This specific pipe lining process creates a protective epoxy coating barrier inside the water pipes to prevent the water from interacting with the pipes, thereby preventing corrosion, pinhole leaks, buildup, discolored water and low flow. While the other possible repair method is a traditional process called a pipe replacement (also called a repipe), pipe lining is becoming increasingly preferred among multifamily properties due to its many benefits and advantages over a repipe.

Why Multifamily Properties Choose This Solution:
  • Residents CAN CONTINUE TO LIVE IN THEIR HOMES during the work
  • It uses a non-destructive process that prevents demolition to the building, its property and landscape
  • It is less expensive than a repipe
  • It is completed much faster than a repipe
  • It is much less disruptive to residents than a repipe
  • It does not create an unsightly and dangerous construction zone
  • It prevents messy, hazardous and tedious asbestos abatement
  • The epoxy coating improves the pipe system’s condition to give it a longer lifespan than brand new pipes
  • It’s environmentally-friendly by reusing the existing pipe system and not creating more waste
  • It’s approved safe for use in water supply pipes, meeting all necessary health standards and requirements, including NSF Standard 61 for a safe drinking water system component
  • It’s proven via independent laboratory studies and through time as effective long-term solution
  • The most prestigious of companies and organizations use pipe lining technology, including the U.S. government, the Navy, CBRE, Transwestern, BP Oil and ExxonMobil, to name a few.


If you’re interested more in how this epoxy coating is applied to a plumbing system, please watch our informational demo videos.


Still wondering if this would be a good solution for your property? Listen to why this HOA Board President and her residents were very satisfied with this technology after encountering chronic pinhole leaks and spending hundreds of thousands of dollars on small, temporary fixes that did not stop future leaks from occurring.
