QUICK REFERENCE
Print this. Tape it next to the regulator. Numbers every tap line should hit.
TEMPERATURE
| Walk-in cooler | 36–38°F (2.2–3.3°C) |
| Glycol bath | 28–30°F (-2.2 to -1.1°C) |
| Beer at faucet | ≤ 40°F (4.4°C) |
PRESSURE

| Nitro stout (75/25 N₂/CO₂) | 30–40 PSI |
LINE RESISTANCE
| 3/16" vinyl | ≈ 3.0 PSI/ft |
| 3/16" Bev-Seal Ultra | ≈ 2.2 PSI/ft |
| 1/4" vinyl | ≈ 0.85 PSI/ft |
| 5/16" vinyl | ≈ 0.4 PSI/ft |
CLEANING CADENCE
| Caustic line clean | Every 14 days |
| Acid line clean | Every 90 days |
| Faucet disassembly | Every 14 days |
| Full line replacement | 12–24 months |
BALANCING FORMULA
For any direct-draw or long-draw system:
Applied PSI = (rise in ft × 0.5) + (line resistance × length in ft) + 1 PSI
Solve for line length when adding a new tap — wrong restriction is the #1 cause of foamy pours in newly installed systems.
