Water Treatment Buyer Checklist

1. Facility & Operation Profile

☐ Facility Type:
☐ Restaurant
☐ Café / Coffee Shop
☐ School / University
☐ Hospital / Healthcare
☐ Government / Federal
☐ Commissary / Production Kitchen

☐ Dishwasher Type:
☐ Undercounter
☐ Door-Type (Hood)
☐ Conveyor
☐ Flight-Type

☐ High-Temp Machine (Booster Required): ☐ Yes ☐ No
☐ Chemical Sanitation System: ☐ Yes ☐ No
☐ Estimated Racks Per Hour: ___________________

Why this matters: Water treatment sizing depends on machine volume and sanitizing method.

‍

2. Incoming Water Quality (Must Be Measured, Not Estimated)

☐ Static Water Pressure: __________ PSI
☐ Incoming Cold Water Temperature: __________ °F
☐ Incoming Hot Water Temperature: __________ °F
☐ Water Hardness Measured? ☐ Yes ☐ No

If Yes: __________ grains per gallon (gpg) or ppm

☐ Iron or Sediment Present? ☐ Yes ☐ No
☐ Chlorine / Chloramine Present? ☐ Yes ☐ No
☐ Visible Scale in Existing Equipment? ☐ Yes ☐ No

Red Flag: “We don’t know our water hardness.”
You cannot properly size water treatment without testing.

‍

3. Required Protection Components (Select All That Apply)

Sediment Filtration (Required for All)

☐ Installed upstream of dish machine
☐ Micron rating appropriate (5–20 micron typical)

Protects:

• Solenoids
• Spray arms
• Valves
• Chemical injectors

‍

Carbon Filtration (Chlorine & Odor Removal)

☐ Installed (if chlorine/chloramine present)
☐ Sized for machine GPM demand

Protects:

• Stainless steel components
• Rinse agent performance
• Chemical sanitizer stability

‍

Water Softener (Scale Control – Warranty Critical)

☐ Installed
☐ Resin tank sized for dishwasher + booster flow
☐ Regeneration schedule verified
☐ Brine tank accessible
☐ Bypass valve installed for service

Required in most regions when hardness exceeds manufacturer limits (often 3–5 gpg).

‍

Reverse Osmosis (RO) (As Required)

☐ Installed (high-end glassware / specialty use)
☐ Dedicated for final rinse only (if required)
☐ Rejection water routed to approved drain

Used for:

• Spot-free glassware
• Bars
• Breweries
• Specialty beverage service

‍

4. Flow Rate & System Capacity Verification

☐ Dishwasher GPM Demand: __________
☐ Booster Heater GPM Demand: __________
☐ Pre-Rinse Hose GPM Demand: __________
☐ Total Simultaneous GPM: __________

☐ Water Treatment System Rated to Handle Total GPM: ☐ Yes ☐ No
☐ Pressure Drop Through Treatment System Acceptable: ☐ Yes ☐ No

Red Flag: Water treatment that restricts flow will cause:

• Poor wash pressure
• Low rinse temperature
• Failed sanitation

‍

5. Installation & Layout Verification

☐ Installed upstream of:
☐ Dishwasher
☐ Booster Heater
☐ Pre-Rinse Hose

☐ Service access clearance maintained
☐ Not installed under electrical panels
☐ No storage piled on top of system
☐ Durable mounting bracket or floor stand used

‍

6. Drainage & Regeneration Waste (Often Overlooked)

☐ Softener regeneration waste piped to approved drain
☐ RO reject water piped to approved drain
☐ No direct sewer connections (air gaps required)
☐ No discharge into storm drains

‍

7. Manufacturer Warranty & Compliance Protection

☐ Dishwasher manufacturer requires water treatment: ☐ Yes ☐ No
☐ Booster heater manufacturer requires water treatment: ☐ Yes ☐ No
☐ Written documentation kept on file
☐ Failure to install water treatment voids warranty: ☐ Yes ☐ No

Many warranty denials are based solely on lack of water treatment.

‍

8. Staff Training & Ongoing Maintenance

☐ Staff trained on:

• Softener operation
• When to call for service

☐ Brine levels checked regularly
☐ Filter change schedule established
☐ Deliming schedule coordinated with treatment system
☐ PM logs include water treatment system

9. Visual Warning Signs of Poor Water Quality

• White scale on machine interior
• Cloudy glassware
• Film on dishes
• Delime alarm constantly triggering
• Booster heater frequent failure
• Spray arms clogging

If any are present → Water treatment is insufficient or failing.

Aldevra Water Treatment Best-Practice Reminder

You can replace a dishwasher. You cannot easily replace damaged plumbing, scaled boosters, or a voided warranty. Water treatment protects everything downstream.
