Water Quality Systems
We believe every home deserves safe, clean, and great-tasting water. Our professional water filtration system installation services help homeowners across Appleton, Green Bay, Oshkosh, and the wider Fox Valley area enjoy healthier water every day.
Whether you’re looking to remove hard water, eliminate contaminants, or improve the taste of your tap water, we offer tailored solutions — including whole house water filters, reverse osmosis water filtration systems, and expert water softener installation.
Whole House Water Filtration Systems
With a whole house water filter, you can ensure that every tap in your home delivers cleaner, healthier water. These systems filter out chlorine, sediment, and other common impurities, protecting your plumbing and improving the taste of your water from every faucet.
Serving homes throughout the Fox Valley, we install filtration systems designed to handle the unique challenges of Wisconsin water.
Water Softener Installation
Hard water is a common issue across Appleton, Green Bay, Oshkosh, and the surrounding communities. Over time, mineral buildup can damage pipes, shorten the life of appliances, and leave spots on dishes and fixtures. Our professional water softener installation services can solve these problems, providing:
-
Softer skin and hair
-
Spot-free dishes
-
Longer-lasting plumbing and appliances
Our team installs high-quality systems customized to your household’s water usage and needs.
Reverse Osmosis Water Filtration
If you're looking for the highest level of purity, reverse osmosis water filtration systems are the perfect choice. These advanced systems remove up to 99% of contaminants, including chlorine, lead, fluoride, and bacteria, giving you fresh, bottle-quality drinking water right from your tap.
We install under-sink units, whole-house systems (including reverse osmosis), and other customized solutions.

Highly recommend Don! He came out to help us when we had a backed up tub and shower drain. Super friendly and knowledgeable, got the job done quickly and cleaned up when he was done. We have another project coming up and are very happy to have him doing the work.

Don and his team have helped us with plumbing emergencies and planned projects in our home and rental property for many years now. We know we can always get help. The entire crew is personable and professional. They just put in a modern kitchen sink, faucet, garbage disposal, air gap… and it is so beautiful! Thank you!!!!

These guys do a ton of work for me and I probably should have given them credit sooner. Today they re-plumbed my kitchen sink, installed a new sink and faucet. They were on time, quick and efficient. We always get great quality and value when we use Reliable Rooter.
