Old water pipes can be a real concern for homeowners, and it's essential to understand the dangers they pose. Lead contamination is a significant risk, especially in pipes made before 1986.

Lead can leach into the water, causing serious health problems, including developmental delays and organ damage. In fact, a single liter of water from a lead-contaminated pipe can contain up to 15 micrograms of lead.

Many old water pipes are made of galvanized steel, which can corrode and lead to leaks. This can cause significant water damage and even lead to mold growth.

Replacing old water pipes is a crucial step in ensuring safe and clean drinking water. The cost of replacement can vary, but it's often a necessary investment to protect your family's health.

Dangers of Old Water Pipes

Old water pipes can be a serious health hazard, especially if they're made from galvanized steel. This type of pipe is coated in a zinc solution to prevent corrosion, but it can eventually start to corrode and release unhealthy heavy metals like lead and cadmium into the water.

Galvanized steel pipes are no longer used in residential plumbing systems, having been replaced by safer options like copper and plastic. If your home was built before 1970 and hasn't had its plumbing upgraded, it likely has galvanized steel pipes.

The problem with galvanized steel pipes isn't the zinc coating itself, but the presence of lead and cadmium that can exist in the zinc due to the galvanizing process. These heavy metals can be particularly hazardous for young children.

If your water is developing a metallic taste, it may be a sign that your old pipes are corroding and releasing these unhealthy substances into the water.

Causes of Problems

Old water pipes can be a real hassle, and sometimes it's hard to figure out why they're causing problems. One common issue is that PVC pipes, which are often used in older systems, can degrade over time.

PVC pipes can become brittle and prone to cracking as they age, especially if they're exposed to UV light or extreme temperatures. This can lead to leaks and other issues.

The pros and cons of PVC pipes are well-documented, but it's worth noting that they can be a bit more prone to problems than other types of pipes.

Harmful Contaminants

Lead is one of the biggest worries when it comes to water contamination, as continual exposure to this toxin can impact your entire body.

Heavy doses of lead can lead to convulsions, comas, and death, while smaller doses can affect your kidneys, liver, eyes, brain, and more.

There is no detectable amount of lead that is safe for human contact, and the results of this material are said to be irreversible.

Old, corroding pipes can harbor lead and other contaminants, making it essential to inspect your plumbing system if you suspect you have such pipes.

Sewer inspections can also help ensure that your waste lines are sanitary and efficient, giving you peace of mind knowing your water is safe to drink.

Insufficient Heating

Insufficient heating of the hot water is a significant issue that can lead to the multiplication of bacteria and germs. This is especially true at lukewarm temperatures.

Bacteria such as Legionella and others thrive in these conditions, making the hot water system a breeding ground for potential health hazards.

Old water pipes are often overlooked, but they can be a major source of contamination.

Pros and Cons

PVC pipes are a common culprit behind many plumbing problems, and understanding their pros and cons can help you identify the root cause of the issue.

However, their flexibility can also be a drawback, making them prone to damage from external forces like freezing temperatures.

PVC pipes are also relatively inexpensive compared to other materials, which can be a significant factor in the decision-making process.

But, their tendency to crack and leak over time can lead to costly repairs down the line.

Their ease of installation is another benefit, as they can be connected using simple fittings and tools.

Unfortunately, these fittings can also be a source of problems if not installed correctly.

The fact that PVC pipes are non-toxic and safe for drinking water is a significant advantage.

However, their chemical makeup can still leach into the water supply under certain conditions.

Overall, understanding the pros and cons of PVC pipes is essential to identifying and fixing plumbing problems effectively.

Identifying Issues

A simple water test can provide certainty about whether old water pipes are causing problems or hiding dangers.

This water analysis can also reveal if your tap water is contaminated, giving you peace of mind.

You can even carry out a water test yourself with the right equipment, available in the IVARIO shop.

Stagnation Due to Rare Use

If water stands in a pipe for too long, it absorbs substances from the pipe and fittings.

The longer water sits, the more likely it is to pick up nickel from alloys, especially at the tap.

Rarely used pipes can harbor bacteria and germs, especially when the water temperature is above 20 degrees Celsius.

Dead pipes are a common cause of stagnation, which can lead to contaminated water.

How to Recognize?

Old water pipes are usually lead pipes, and they're pretty easy to spot. They have a distinctive lead-grey color, unless they've been painted over.

Lead pipes are not screwed together like modern materials, and the pipe diameter often varies. Joints between two pipes have beads, which is a dead giveaway.

If you tap a lead pipe with a hammer, it will sound rather dull. And, as a fun fact, lead is non-magnetic, so it won't react to a magnet.

Copper pipes, on the other hand, have a copper-red color and a rather small diameter. They're pretty easy to recognize, even for the amateur.

If you're not sure what kind of pipes you have, it's always a good idea to seek the advice of an expert to determine whether they need to be replaced.

A Simple Test Provides Certainty
