"I was in dire need of a plumber because the valve that adds water to my pool was broken and it would not shut off. We had to shut off the water to my house to prevent flooding of the pool. Enter Rooter ER & Plumbing to the rescue. He was extremely knowledgeable about what was required just by looking at the picture I sent over the phone. He gave me options and quite reasonable prices. Doing the work, he was extremely efficient and thorough. He would not stop until it was up to a standard that he expected of himself for his own home. When I went out to look at/inspect his work, he was extremely patient and he explained to me everything that he had done and the benefits of getting this done. Being a complete novice in the realm of plumbing, I was extremely grateful for him taking the time to explain this to me. I was extremely happy with his work, and I would recommend him to anyone that needs a friendly neighborhood plumber."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

Water Softeners FAQs, answered by experts

There are many possibilities for why your shower’s water pressure is low. It might be a simple-to-fix issue like the water valves being partially turned off, a dirty showerhead or hose, leaks in the plumbing, or an old showerhead. However, low water pressure in the shower could also indicate a larger issue with your home’s plumbing system.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

The most effective way to fix hard water in your shower is by installing a whole-home water softening system. This system treats water as it enters your home, removing the minerals that cause hardness before they can reach your shower or any other fixtures. While this is the most comprehensive solution, other methods are often temporary fixes. For a more affordable and shower-specific option, you can install a water-softening showerhead or a shower filter. However, these filters are generally less effective and may not remove all the contaminants that lead to limescale and hard water stains. By implementing a water softening solution, you can expect a reduction in mineral deposits and enjoy the benefits of cleaner-feeling hair and skin.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.
