What’s in well water in Fresno?
Hard Water
Well water in the Central Valley is often much harder than city water — it can test well above Fresno’s city average of 7.5 grains per gallon, depending on your well and your street. That hardness leaves scale in your pipes and water heater, spots on dishes and glassware, and dry skin and hair. We test your hardness at your sink, so we know your exact number before we size a softener.
Iron and Sulfur
Iron and sulfur are common in well water, and you’ll know it — iron leaves orange stains on sinks and laundry, sulfur smells like rotten eggs. Both can damage fixtures and make water unpleasant to use. We test for iron and sulfur, and if they’re present, we size a system that handles them.
Nitrates and Bacteria
Nitrates from agricultural runoff and bacteria from septic systems or surface water can show up in well water, and unlike city water, well water isn’t disinfected or tested by anyone else. The EPA’s guide to private drinking water wells recommends doing well water testing at least once a year for bacteria, nitrate, total dissolved solids, and ph. We test for nitrates and bacteria, and if they’re present, we tell you what it means and what system will reduce them — reverse osmosis for drinking water, and the right whole-home system for the rest.
Sizing the right system
There’s no one-size well system — it depends on your hardness, iron, sulfur, nitrates, and how much water your household uses. That’s why we well water test first, then size. We tell you what your numbers mean in plain words, recommend the system that fits your well, and install it free with a lifetime warranty.

Well Water Testing Fresno, CA Frequently Asked Questions
1. How much does well water testing cost?
Our well water test is free — we test at your home, at your sink, with no obligation. Book a free water test and we’ll test your hardness, iron, sulfur, and more, and tell you what the numbers mean.
2. My well water smells like rotten eggs — what is that?
That’s sulfur, usually hydrogen sulfide gas in well water. It’s common in Central Valley wells, and it’s treatable — our Dual Tank Well Water system is built for iron and sulfur.
3. How long does a well water test take?
About 20-30 minutes at your home. We test at your sink, explain the results on the spot, and tell you what system fits your well — no waiting for lab results for the basic test.
4. Do I need a different system for well water than city water?
Yes, usually. Well water isn’t treated like city water, so it can have higher hardness, iron, sulfur, nitrates, and bacteria. We test first, then size a system for your specific well — some wells only need to treat the hardness, and some wells need a whole home RO because of how much contaminants are in their drinking water. We will test the water and let you know exactly what you need.
