Why Your Old Galvanized Water Lines Are Putting Your Flow to Shame

Do you feel like your water pressure is weaker than a toddler's handshake? You might have old galvanized water lines to blame. As a licensed general contractor specializing in bathroom and kitchen renovations in Montreal, I've seen my fair share of rusty pipes. But did you know that galvanic corrosion can exacerbate the problem?



First things first, let's talk about what galvanized pipes are.


These pipes are made of steel coated with a layer of zinc to prevent rust and corrosion. They were commonly used in residential plumbing until the 1960s, when copper and plastic became more popular.


Now, let's talk about galvanic corrosion.


This type of corrosion happens when two different metals come into contact with each other in the presence of an electrolyte, such as water. The result? One metal corrodes faster than it would on its own.


So, why does this matter for your water flow?



Well, as galvanized pipes age, the zinc coating can wear away, leaving the steel underneath vulnerable to corrosion. When this corrosion happens, the pipes can become narrower, leading to reduced water flow. And, if you have other types of metal plumbing (like copper) connected to your galvanized pipes, the galvanic corrosion can exacerbate the problem even more.


How Can I Fix It?


The good news is that there are solutions to this problem. One option is to replace your galvanized pipes with modern plumbing materials, such as copper or plastic. This can improve your water flow and reduce the risk of leaks caused by corroded pipes.


Another solution is to install dielectric unions, which are fittings that separate different types of metal plumbing to prevent galvanic corrosion. This can help prolong the life of your galvanized pipes and keep your water flow strong.


In conclusion, if you're experiencing reduced water flow in your home, it might be time to take a closer look at your plumbing. Old galvanized pipes can be the culprit, and galvanic corrosion can make the problem worse. As a licensed general contractor specializing in bathroom and kitchen renovations in Montreal, I can help you assess your plumbing and recommend the best solutions for your home. Don't let weak water pressure get you down - let's crank up the volume AND the pressure!
