How much does a water filtration system replacement cost?

A water filtration system replacement is confirmed after an in‑home assessment, and financing promos like $99/mo installs with a free proposal are available for new systems. Most cost depends on matching system size and media to your home’s water quality and usage.

We install WaterTech whole‑home systems for homeowners in the Eagle area. A technician will test your water, inspect existing plumbing, and provide a written report; common offers include a $99 New Water Filtration Assessment + 4 Hour Arrival or a $49 Repair Assessment + 4 Hour Arrival, with 100% satisfaction and no dispatch fees. A careful on‑site check also shows if current piping or a bypass can be reused to keep costs down.

What drives total price:

• Home size and peak-flow needs
• Target contaminants and filtration technology (lead, PFAS, cysts, chlorine/chloramine)
• Plumbing changes or integration with other equipment
• Location and access for the installation
