🆚 Pressure-Balancing vs Thermostatic

Pressure-Balancing Valve (ASSE 1016 Type P)

FL Code Minimum Most Common Single Control

Balances hot/cold ratio when pressure changes (toilet flush). Limits temperature swing to ±3°F. Max temp set via internal stop. Does NOT hold exact temperature. Required in all FL residential showers since 2006 FBC adoption.

Thermostatic Valve (ASSE 1016 Type T)

Precise Temp Dual Control Premium

Maintains exact temperature within ±1°F regardless of pressure OR supply temp changes. Separate volume and temperature controls. Ideal for multi-spray systems, steam rooms, commercial. Required in FL medical/assisted living facilities.

Combination Thermostatic + Volume Control

Best of Both Multi-Outlet FL Medical OK

Thermostatic cartridge + separate diverter/volume valves. Allows multiple outlets (shower, rain head, hand shower, tub spout) at precise temperature. Most commercial and hospitality installs in FL use this configuration.

⚠️ Florida's ambient water temp (72°F+) means tankless WH needs less rise — but Legionella control still requires 120°F at WH. Solution: ASSE 1016/1070 mixing valve between WH and distribution.

🔄 FL Hot Water Strategy: 120°F Rule

Store / heat at 140°F minimum — kills Legionella bacteria. Tank WH should be set to 140°F, even if you add a mixing valve downstream (FL DOH recommendation).
Install ASSE 1070 mixing valve at WH — reduces mixed supply to 120°F before entering distribution system. Required in FL medical/senior facilities. Strongly recommended for all FL homes with children or elderly.
ASSE 1016 shower valve limits to 120°F at fixture — the internal hot stop prevents the valve from delivering water above the preset maximum. Set during installation, requires tool to adjust.
For vulnerable users: set shower valve stop to 110°F — pediatricians recommend 110°F max for children under 5. Mobility-impaired users may not be able to react to hot water quickly enough at 120°F.

📋 FL Shower Valve Code Requirements

Florida Building Code (FBC) adopts ASSE 1016 for all shower and tub/shower combinations. This has been required since the 2004 FBC edition — any shower built after 2004 must have an ASSE 1016 or equivalent anti-scald valve.
FBC R2708.1 / FPC 424.3 — Anti-Scald Mandatory — All shower and tub/shower valves must be ASSE 1016 listed. Applies to new construction AND fixture replacement. Maximum 120°F at shower outlet. No exceptions for owner-occupied single-family in FL.
ASSE 1016 Internal Stop Setting — The hot stop (limit stop) must be set to prevent outlet above 120°F. Factory-set at 120°F but must be field-verified. Plumber is responsible for setting and documenting during rough-in inspection.
FL Medical/Assisted Living — ASSE 1070 Required — AHCA (Agency for Health Care Administration) requires ASSE 1070 point-of-use mixing valves in all patient/resident bathing areas in addition to ASSE 1016 at the fixture. Max 110°F in care settings.
Permit Required for Valve Replacement? — FL Statute 489.105(3)(m) exempts minor repairs from permit (washer replacement, etc.). However, replacing a valve body or cartridge that changes the anti-scald function IS a plumbing alteration requiring permit in most FL jurisdictions. Check with your building department — policies vary by county.
ADA Accessible Showers (FL Accessibility Code) — Roll-in and transfer showers must have ASSE 1016 thermostatic or pressure-balancing valve with hand shower on sliding bar (48" to 72" height). Controls must be operable with closed fist, reachable from outside shower.
FL Short-Term Rental / Airbnb Properties — DBPR requires anti-scald compliance for vacation rentals. Annual inspection may check shower valve function. Non-compliant valve = potential license suspension. ASSE 1016 must be documented.
Water Pressure Requirement — ASSE 1016 valves require minimum 20 PSI dynamic pressure to function properly. FL well water systems must have properly sized pressure tank. Low pressure bypasses the anti-scald mechanism on some models.

✅ Shower Valve Compliance Checklist

Valve is ASSE 1016 listed (marked on valve body or packaging)
Hot stop set to max 120°F (verify with thermometer)
For medical/elderly: ASSE 1070 mixing valve installed at WH
Permit pulled if replacing valve body (check local jurisdiction)
ADA controls reachable from outside shower (if applicable)
Minimum 20 PSI dynamic water pressure at shower valve
Expansion tank on water heater (if closed system — FL code)
