FAQs
Choosing the perfect water treatment system depends on your specific water quality, household size, and needs. We make it easy with our 3-step process:
Water quality testing – analyze your water for contaminants, hardness, and other factors.
Personalized Consultation – Our experts recommend systems based on your results, budget, and water usage.
Customized Solution – From whole-house filtration to targeted solutions (e.g., RO for drinking water, softeners for hard water), we tailor the system to your home.
To determine your water flow rate in gallons per minute (GPM), follow these simple steps:
Prepare for Testing:
- Prepare for Testing:
- Ensure all water fixtures in your home are turned off
- Select the faucet closest to your main water supply line (usually the kitchen sink or an outdoor spigot)
- Conduct the Test:
- Fully open the selected faucet
- Time how many seconds it takes to fill a 1-gallon container
- Repeat the test 2-3 times for accuracy
- Calculate Your Flow Rate:
Use this formula: Flow Rate (GPM) = 60 ÷ Fill Time (seconds)Example Calculation:- If your 1-gallon container fills in 15 seconds
- 60 ÷ 15 = 4 GPM
For more precise measurements or whole-home flow rate analysis, contact our water system specialists. We can help you determine if your current flow rate meets the requirements for any water treatment systems you’re considering.

1. Check Multiple Fixtures
Test water pressure at different faucets, showers, and appliances (e.g., kitchen sink, bathroom sink, outdoor hose).
If only one fixture has low pressure, the problem is likely localized (clogged aerator, faulty valve, or pipe issue).
If all fixtures have low pressure, the issue is systemic (main supply, pressure regulator, or water heater).
2. Inspect the Aerator or Showerhead
Unscrew the faucet aerator or showerhead and check for mineral deposits, debris, or rust.
Soak it in vinegar overnight to dissolve buildup, then rinse and reattach.
3. Check the Main Shutoff Valve
Locate the main water shutoff valve (usually near the water meter or where the main line enters the house).
Ensure it’s fully open (turn clockwise to close, counterclockwise to open).
1. Activated Carbon Filters
- Removes:
✅ Chlorine & chloramines
✅ Bad tastes & odors (e.g., sulfur)
✅ Volatile Organic Compounds (VOCs)
✅ Some pesticides & herbicides
❌ Does not remove heavy metals, dissolved minerals, or microbes
2. Reverse Osmosis (RO) Systems
- Removes:
✅ Heavy metals (lead, arsenic, mercury, cadmium)
✅ Dissolved salts (fluoride, nitrates, sulfates)
✅ Microplastics & sediment
✅ Bacteria & viruses (if combined with UV)
✅ Chlorine & chemicals (with carbon pre-filter)
❌ May remove beneficial minerals (can be remineralized)
3. Water Softeners (Ion Exchange)
- Targets:
✅ Calcium & magnesium (hardness)
✅ Low levels of iron & manganese
❌ Does not remove bacteria, chlorine, or heavy metals
4. UV Purifiers
- Kills:
✅ Bacteria (E. coli, coliform)
✅ Viruses (rotavirus, hepatitis)
✅ Protozoa (Giardia, Cryptosporidium)
❌ Does not remove chemicals, metals, or sediment
5. Sediment Filters
- Removes:
✅ Sand, rust, dirt
✅ Large particles & silt
❌ Does not remove dissolved contaminants
6. Whole-House Filtration Systems
Combines multiple methods (carbon + sediment + UV) for broad protection.
- UV: Kills bacteria/viruses but doesn’t remove chemicals or particles.
- RO (Reverse Osmosis): Removes 95–99% of contaminants (heavy metals, dissolved salts) but requires electricity.
- Activated Carbon: Absorbs chlorine, odors, and organic compounds—ideal for pre-filtration.
