Custom Walkthrough & On-Site Water Testing in Modesto, CA

Wondering what's in your tap water? We'll come to your home in the Modesto area, test it and show you exactly what's in it.

Hard water usually isn't a health risk, but it builds scale in your pipes and fixtures and wears out water heaters, dishwashers and other appliances sooner. Testing first tells us exactly what's in your water, so you don't pay for equipment you don't need or end up with a filter too small to fix the problem.

What happens at the walkthrough

Here's what the visit looks like:

  1. We hear what's going on

    First, we ask what you notice day to day: a chlorine taste, spots on your glasses, a smell, or scale building up.
  2. We check any system you have

    If you already have a softener or filter, we check that it's working and tell you if it needs service.
  3. We test your water

    We take water right from your tap and test it for:
    • Hardness (the calcium and magnesium that cause scale)
    • Total dissolved solids (TDS)
    • Chlorine
    • pH
    • Sediment and clarity
  4. We look at your plumbing and water use

    We check your water pressure, your main plumbing and how much water your household uses, so any system we suggest fits your home.
  5. We give you a straight answer

    We go over every reading with you and give you an honest recommendation for your home, with no pressure.
