Why Your Home's Water Quality Matters

Clean tap water plays a huge role in keeping your family safe and healthy. Hard minerals, chemicals, or contaminants can sneak into your pipes over time. That’s why paying attention to water quality from the tap makes a real difference. Here are some key benefits:

  • Protects Family Health: It keeps out chlorine, heavy metals like lead or mercury, and bacteria that can cause illness. Drinking cleaner water gives you peace of mind.
  • Better Tasting and Smelling Water: When chlorine and organic contaminants are filtered out, water tastes fresher and smells more natural.
  • Crystal-Clear Showers and Appliances: Filtration prevents mineral buildup inside pipes, water heaters, and fixtures. That makes showers feel softer and appliances last longer.
  • Saves Money on Plumbing Repairs: Less mineral scale buildup means fewer leaks and clogs in your pipes.
  • Improved Appliance Efficiency: Your dishwasher, coffee maker, and washing machine run more efficiently. Purified water sometimes means energy savings.

Our service tech was knowledgeable and took the time to show us what was going on with our AC unit. I was kept up to date with texts throughout the process before he arrived. He took the time to ask if we had any questions. Would highly recommend Arlinghaus!
Arlinghaus was great to get someone to my home immediately as I was dealing with a burst pipe. Mike Thomas was so kind and professional, and thorough in his work. The rates were very reasonable for the wonderful service provided. I certainly will be calling them back if I have any future issues (though I hope I don't!)
I contacted Arlinghaus to have our hot water heater replaced and water softener system installed. The two techs that came out and worked on our project, Derek Mullins and Claude Jones, were excellent! Super nice guys, kept us informed, and did a fantastic job on our house. I appreciate their professional manner and knowledge on this job and I would recommend them for future work. Thank you guys for restoring the hot water in our house and for installing our new water softener, we are so happy for these upgrades!!

Water Filtration System Installation

Installing a whole-house water filtration system is one of the smartest upgrades a homeowner can make, and we’ve helped many families take the leap. These systems don’t just filter water at the kitchen tap — they treat every drop flowing into your home. Showers, sinks, washing machines, you name it. We handle water filtration system installation with precision, using trusted brands and proven methods.

Our plumbing installation services also include water softeners to help homeowners tackle hard minerals like calcium and magnesium. Soft water preserves your pipes, improves soap lather, and keeps skin feeling better. A properly installed whole-house water filtration system or water softening system will bring clarity to every faucet.

Water Conditioning Services

If your water leaves your skin dry, soap doesn’t lather well, or appliances seem to struggle, you’re probably dealing with hard water. That’s where water conditioning services come in. These systems help break down the minerals that cause buildup and mess with your water’s feel and function.

The Importance of Professional Water Purification Services

DIY filters look tempting, but professional-grade systems deliver lasting performance. Filling a pitcher isn’t the same as intercepting contaminants at the cold water main before they reach every tap in the house.

Our experts will help you choose a whole-house water filtration system that matches your needs, install the water treatment system correctly, and monitor performance over time. This gives you complete peace of mind — not a one-off purchase with unknown results.

Cleaner water from every tap changes everyday life. It makes drinking safer, showers nicer, plumbing trouble-free, and appliances long-lasting. At Arlinghaus, we’ve built trust through caring service, expert teams, and an award-winning reputation.
