What Is Hard Water Doing to Your Plumbing System? 

You might know that hard water can damage your clothing, affect the taste of tap water, and shorten the lifespan of appliances. Unfortunately, many homeowners don’t realize that hard water also has a negative impact on their plumbing equipment.


Once you discover the effects of hard water, you’ll see why it’s important to schedule professional hard water treatment in Larchmont & Warminster, PA.


Inhibit Water Pressure

You can usually tell that you have hard water by looking at your faucets and shower heads. If you have hard water, you’ll see a whitish-green buildup on these fixtures.

 

In addition to tarnishing the fixtures, this buildup of minerals slows the flow of water. There may be a similar buildup throughout your pipes, reducing the amount of space for water to flow. This results in reduced water pressure and slower flow.


Increase Water Heater Wear and Tear

Protecting your water heater is one of the most important reasons for hard water treatment in Warminster, PA.


Mineral buildup is more dangerous once it accesses your water heater because the heating process crystallizes the minerals and creates hard sediment. That sediment can coat the bottom of the tank. It can also damage heat exchangers in tankless water heaters.


Higher Risk of Pipe Corrosion

Mineral sediment weakens the pipes throughout your plumbing system. It forms a thick layer that coats the inner lining of the pipes. The minerals in hard water react with copper and lead pipes to create a chemical process that corrodes the metal. Over time, this process leads to frequent leaks and burst pipes.


Poor Faucet and Shower Performance

As mineral sediment builds up on faucets and shower heads, it blocks the spouts. In addition to the lower pressure that results from mineral buildup inside the pipes, mineral formation on faucet spouts stops the release of water. If you frequently need faucet repairs or replacement, you might need water softening to address this issue.
