COMPATIBILITY
System Integration
The Watts BB-M101 is designed for the BB-S101 whole home water system and comes pre-installed with that unit. It can also be retrofitted to any existing Big Bubba housing or BB-S100 whole home system, giving older installations the benefit of smart monitoring without replacing the entire filtration setup. The 1 inch NPT connections match standard Big Bubba plumbing configurations for straightforward integration.
🔧 Pro Tip: Set your filter capacity 10% lower than the manufacturer's rated gallons in the app settings. This buffer ensures you receive replacement alerts before filtration performance drops, not after.
