Water Filtration System - Staff Guide
iSpring RCB3P Reverse Osmosis System - Why clean water matters for every drink.
⚡ What You Need to Know
Where is the filtered water?
- Special faucet on sink (labeled "RO" or "Filtered")
- Turn on just like regular faucet
- Water flows slower than tap water (this is normal!)
When to use filtered water:
- ✅ ALL drinks (milk tea, coffee, fruit tea, etc.)
- ✅ Making ice
- ✅ Espresso machine water tank
- ✅ Hot water dispenser
- ✅ Any water that customers will drink
When NOT to use filtered water:
- ❌ Mopping floors
- ❌ Handwashing
- ❌ Dishwashing (regular tap is fine)
Why Filtered Water Matters
Clean water = better tasting drinks! Our RO system removes chlorine, minerals, and impurities that affect taste. Every drink you make will taste cleaner and better.
🚰 How to Use the RO System
Getting Filtered Water:
- Turn on RO faucet (separate from regular tap)
- Water flows slowly - about 5 minutes per gallon (normal!)
- Fill your container - pitcher, espresso machine tank, hot water dispenser
- Turn off when done
Tips:
- Fill containers ahead of time during slow periods
- Keep a pitcher of RO water ready
- Takes ~5 min to fill 1 gallon (be patient!)
- Slower flow = more thorough filtering
🧊 Why Clean Water = Better Drinks
What the RO system removes:
- ✅ Chlorine (chemical taste)
- ✅ Minerals that cause scale buildup
- ✅ Heavy metals
- ✅ Bad taste and odors
- ✅ Impurities
Results:
- 🫖 Tea tastes cleaner, true flavors come through
- ☕ Coffee/espresso tastes better
- 🥤 Milk tea is smoother
- 🧊 Ice is crystal clear (not cloudy)
- ⚙️ Equipment lasts longer (no scale buildup)
⚠️ What to Watch For
Slow or No Water Flow
What to do:
- Normal: RO water is always slower than tap
- Problem: If it stops completely or becomes much slower
- Tell manager - filters may need replacing
Water Tastes Bad
What to do:
- This shouldn't happen with RO water!
- Tell manager immediately - filters need attention
- Use bottled water temporarily if needed
Leaking Under Sink
What to do:
- Tell manager right away
- Don't use RO faucet until fixed
- Use bottled water as backup
🆘 When to Get Manager
Get help if:
- No water coming from RO faucet
- Water tastes weird or bad
- Leaking under sink
- Strange sounds from under sink
- RO faucet broken or loose
This is important equipment - report problems immediately!
💡 What New Staff Should Know
- RO water is for drinks only - not for cleaning
- Always flows slower than regular tap (by design)
- Fills espresso machine faster if you use a pitcher
- Check water before shift - is pitcher full and ready?
- Better water = happier customers - it really makes a difference!
❓ Quick Questions
Q: Why does filtered water flow so slowly? A: RO filters water very thoroughly - removes 99%+ of impurities. This takes time! It's normal.
Q: Can I just use tap water for drinks? A: NO! Tap water has chlorine and minerals that taste bad and damage equipment. Always use RO water.
Q: Which faucet is the filtered water? A: Look for the separate faucet labeled "RO" or "Filtered". Ask your trainer to show you.
Q: What if RO faucet isn't working? A: Tell manager immediately. Use bottled water as temporary backup.
Q: Do I need to do anything to maintain it? A: No - manager handles all maintenance. Just report any problems.
Q: Water looks slightly cloudy - is that okay? A: Tiny air bubbles are normal. If it stays cloudy or colored, tell manager.

How RO Works
Process:
- Pre-filters remove sediment and chlorine
- RO membrane filters out dissolved solids, heavy metals, bacteria (99%+)
- Post-filter polishes water for taste
- Clean water to faucet
- Waste water (concentrate) to drain
Filter Replacement Schedule
Critical Maintenance
Filters MUST be replaced on schedule. Old filters reduce quality and can damage the expensive RO membrane!
| Filter | Replace Every | Cost |
|---|---|---|
| Sediment Pre-Filter | 6-12 months | $15-25 |
| Carbon Pre-Filters | 6-12 months | $20-30 each |
| RO Membrane | 2-3 years | $80-120 |
| Post-Carbon Filter | 12 months | $15-25 |
Annual Filter Cost: ~$110-140/year Compared to Buying Bottled Water: Saves $3,000+/year!
Monthly Maintenance
Manager/Trained Staff:
- Check for leaks (all connections)
- Verify pressure gauge reading (40-60 PSI normal)
- Check water flow rate (time filling 1 gallon)
- Inspect tubing for kinks or damage
- Listen for pump noise (should be quiet hum)
- Clean RO faucet, remove mineral buildup
Filter Replacement Process
Before Starting:
- Order correct replacement filters
- Have towels ready (water will drip)
- Turn off water supply to system
- Relieve pressure (open faucet)
Steps:
- Turn off feed water valve
- Open RO faucet to relieve pressure
- Unscrew filter housing (counterclockwise)
- Remove old filter
- Insert new filter
- Check o-ring condition (replace if worn)
- Reinstall housing (hand-tighten, don't overtighten)
- Turn water supply back on
- Flush new filter 5-10 minutes
- Check for leaks
- Mark replacement date on filter
RO Membrane Replacement (Every 2-3 Years)
When to Replace:
- Every 2-3 years (typical)
- TDS output increases significantly (>50 ppm)
- Flow rate drops dramatically
- After replacing pre-filters doesn't help
Professional replacement recommended - more complex, requires sanitization.
Water Quality Testing
TDS Testing (Total Dissolved Solids):
Purchase TDS meter ($10-20) and test monthly:
- Good RO Water: 0-50 ppm (lower is better)
- Fair: 50-100 ppm (membrane still working)
- Replace Soon: 100-200 ppm
- Poor: 200+ ppm (replace filters/membrane)
Baseline:
- Test inlet (tap water): typically 200-500 ppm
- Test outlet (RO water): should be <50 ppm
- Record readings monthly
- Increase of 50+ ppm indicates filter issue
Troubleshooting
Low Water Flow:
- Filters clogged → Replace pre-filters
- Membrane fouled → Replace RO membrane
- Low pressure → Check booster pump operation
- Kinked tubing → Straighten water lines
- Closed valve → Verify all valves open
Water Tastes Bad:
- Old carbon filters → Replace carbon pre and post-filters
- Old membrane → Replace RO membrane if >3 years
- System not flushed → Flush for 20 minutes
- Contaminated storage → Flush thoroughly
System Leaking:
- Loose housing → Tighten filter housing (don't overtighten)
- Bad o-ring → Replace o-ring gasket
- Cracked housing → Replace filter housing
- Loose fitting → Tighten push-fit connections
- Damaged tubing → Replace section of tubing
High TDS Reading (>50 ppm):
- Old membrane → Replace RO membrane
- Chlorine damage → Replace carbon pre-filters first
- Membrane bypass → Check membrane seals
- Defective membrane → Replace under warranty
Loud Pump Noise:
- Low water pressure → Check feed water pressure
- Air in system → Flush to remove air bubbles
- Pump failure → May need pump replacement
- Vibration → Secure pump mounting
Constant Drain Water:
- Check valve failure → Replace check valve
- Auto-shut-off valve issue → Check ASO valve
- System not reaching shut-off pressure → Check membrane, filters
Emergency Procedures
System Leak:
- Turn off feed water valve immediately
- Turn off under-sink main if needed
- Dry area to prevent damage
- Identify leak source
- Tighten or repair
- Monitor for 30 minutes after fix
No Water:
- Check feed water valve is open
- Check booster pump is running
- Verify no kinked lines
- Check filter housings secured
- Call plumber if still no flow
Brown/Cloudy Water:
- Don't serve to customers
- Flush system for 10 minutes
- If persists, check filters
- Replace filters if old
- Test water before resuming use
