What to Ask Before Hiring
- 1. Is your pricing fully inclusive? (Labor, parts, permit if needed)
- 2. Who handles warranty claims? (You or the manufacturer?)
- 3. Are your installers licensed plumbers? (Required in Colorado)
- 4. What is the expected lifespan of this specific unit?
- 5. How much water does this unit waste per regeneration?
- 6. Do you offer an ongoing maintenance plan?
- 7. Can you provide references from my specific neighborhood?
- 8. What happens if I move? (Can the system be relocated?)
Red Flags to Watch For
Be cautious if a company exhibits any of these behaviors during a sales pitch:
- High-pressure tactics: Forcing a "sign today for a discount" decision.
- Exaggerated test results: Making tap water seem dangerous using cheap precipitation tests (Denver water is safe, just hard).
- No written quotes: Refusing to leave pricing information with you.
- Cash-only payment: Or pushing excessive, high-interest financing.
- Trashing competitors: Focusing more on why others are bad rather than why their system is good.
- Unlicensed installers: A handyman rather than a licensed plumbing professional.
