Why Should You Replace Galvanized Water Mains

As part of a periodic plumbing systems appraisal, every homeowner should ensure that his water supply distribution system is in perfect condition. The proper functioning of this system is critical because it ensures uninterrupted flow of water to the different locations inside. Since your water mains are the most important component of this system you should pay special attention here. By checking your water mains periodically and carrying out repairs quickly and effectively you can avert major problems that could leave you high and dry, quite literally!

Plumbing problems resulting in water supply disruption occur most frequently in homes with old fashioned galvanized water mains. If your water bills have been steadily soaring and you have been noticing damp patches or water puddles in your yard, then you probably have a malfunctioning galvanized water main too.

Common Problems with Galvanized Water Pipes

Galvanized iron pipes were used in many older homes to replace lead pipes when people came to realize that the passage of water through these pipes caused lead poisoning. In a galvanized pipe, molten zinc was usually applied over a pre- formed steel pipe so that it would be corrosion free. Although these pipes were quite popular about 70 years back, there are many better options today that are easier to maintain and are longer lasting than these.

If your home has the old fashioned galvanized water mains, it is best to have a plumber over right away to see if they need to be replaced. This is because, in spite of the zinc coating, galvanized pipes do corrode in time. They are also prone to blockage resulting from a build up of minerals inside. If your galvanized pipes are no longer in perfect condition you may notice one or all of these indications:

• The water has a metallic taste
• There is a high level of zinc or iron in the water
• The water is colored (usually brownish or reddish)
• The water flow through the pipe is reduced

Replacing Galvanized Mains

When you start noticing any of the warning signs, it is time for you to call in a professional plumbing service. The plumber will be able to tell you if it is corroded galvanized water mains that are the cause of these problems. He will also be able to assess the condition of your mains and give you correct advice about replacing them.

Your home’s water mains may be embedded deep within the earth, making it impossible for you see if they are damaged. This also prevents you from carrying out any DIY repairs on the pipe yourself. When it comes to your water mains, it is actually a good idea to avoid trying to fix it yourself. Remember that before starting any kind of work on the main lines, you have to ensure that there is no water flow through it. A professional plumber will have the right equipment to locate the problem area so that he can isolate that portion of the line. He will also know how to turn off water supply to that specific portion of the lines so that he can repair the damage. In short, you can ensure an effective solution to the problem only when you hire a professional to do the job.
