When should you replace your water softener system?

Typically, a water softener system should be replaced every 10 to 15 years. This will depend on the type of system installed and how hard the water is in your area.

If you notice any issues with water quality, you should call Mainstream to inspect your system. Stiffer clothes, deposits in the water, build-up on your faucets can all be signs of issues with your softener system.

Mainstream can improve your water quality today!

Why wouldn’t you want the best water quality possible for your home and your family? Call Mainstream today at (509) 237-6483 and schedule a water softener inspection. Our experts will determine if you need repairs or a new system and make the necessary recommendations to ensure your water is as soft as it can be.

Our home is 66 years young and it was time to replace the original water lines and sewer lines. I was amazed that they were able to streamline, fix old plumbing mistakes and make our entire water system user friendly. Thank you Cody, Donovan and the third guy that I can't remember his name. They were all professional, polite and knowledgeable.

Great Service

We had some plumbing work done by Mainstream. The plumber (Sam) they sent out was GREAT. He listened to what we wanted done; gave us advice about things that could become issues and was very conscientious. We took his advice about our 15+ year old water heater and replaced it. My husband raves about how great it is to have really hot water. We plan to have Mainstream do work for us in the future.

Very Professional

It was really shocking the amount of damage our pipes had and mr Johnson helped to explain what the issue was... He worked within our budget and created a couple of quotes with positive solutions. We went with the one we felt was necessary and he worked quickly getting that issue resolved. Very professional and knowledgeable.
