The U.S. Geological Survey classifies water hardness on this scale:
- Soft: 0–60 mg/L
- Moderately hard: 61–120 mg/L
- Hard: 121–180 mg/L
- Very hard: 180+ mg/L
The water in Chandler sits within that hard range, with the average of 165 mg/L, and over time, it can cause mineral buildup in pipes. As those deposits thicken, they can restrict water flow and trap soap residue, grease, hair, and other debris. It’s why you see drain clogs and slow-draining fixtures so commonly.
What Hard Water Does Inside Your Plumbing
Hard water has higher levels of dissolved minerals, primarily calcium and magnesium. As water travels through pipes, these minerals do not simply pass through the system. Instead, they can attach to pipe surfaces and gradually accumulate.
Unlike some other types of clogs, hard water drain buildup usually develops slowly. You might notice minor changes in water flow long before a major blockage forms.
Here are some of the things that happen.
Reduced Pipe Diameter
Even a thin layer of scale can reduce the amount of space available for water to move through the pipe. As that opening becomes smaller, water drains more slowly and more gunk can get trapped.
Rough Pipe Surfaces
Scale buildup creates uneven surfaces inside pipes. It’s the rough surface that helps grease, soap residue, hair, and food particles cling to the pipe walls instead of washing away.
Slow Draining and Clogs
As layers accumulate, the pipe becomes more restricted and draining starts to slow. Eventually, the mineral deposits and debris can clog your drains.
Gurgling Sounds or Lower Water Pressure
You may notice gurgling sounds coming from your pipes or a drop in water pressure from hard water drain buildup.
What You Can Do to Reduce Hard Water Drain Buildup
While Chandler’s water naturally contains minerals, there are some things you can do to limit mineral buildup in pipes.
Schedule Periodic Drain Maintenance
Routine drain maintenance can help remove early buildup before it becomes severe. Regular drain cleaning can help, especially in kitchens where grease can accumulate or bathrooms where soap adds to the mineral buildup in pipes.
Avoid Chemical Drain Cleaners
Chemical drain cleaners are often used as a quick fix for slow drains. However, these products typically dissolve organic material rather than mineral deposits. In some cases, repeated chemical use can damage plumbing pipes while leaving the underlying scale intact.
Consider Installing a Water Softener
Installing a water softener can help remove calcium and magnesium from the water supply before it enters your plumbing system.
Address Slow Drains Early
When your sinks or tubs are draining slowly, you’ll want to deal with them early to prevent mineral buildup in pipes. It won’t get better on its own, and the more buildup there is, the more extensive the cleaning job will be.
When Professional Drain Cleaning Is Necessary
At some point, the mineral deposits can get thick enough that basic household cleaners will no longer get the job done. Professional plumbers use specialized tools to remove buildup safely without damaging your plumbing system. This might include:
- High-pressure water jetting (hydro jetting) to break apart scale and debris inside pipes, restoring the pipe’s flow capacity.
- Camera inspections to look at the inside of the drain lines and identify the exact cause of clogs.
These diagnostic tools help technicians determine whether the issue is buildup, a deeper obstruction, or a more serious pipe problem.
