⚡ Pressure Tank Sizing Calculator
An undersized pressure tank causes short-cycling — the pump turns on and off rapidly, destroying the motor. In FL's hot climate, a short-cycling pump fails 2–3× faster than properly sized systems.
🔍 FL Pressure System Diagnostics
⚡ Short Cycling (Pump clicking on/off rapidly)
Most common FL well complaint
Waterlogged pressure tank — bladder or diaphragm has failed, tank lost air charge. In FL's high humidity, tank corrosion accelerates. Replace pressure tank. Typical FL tank life: 8–12 years in coastal areas, 12–18 years inland.
Urgency: HighFix: Tank replacement
📉 Low Water Pressure Throughout Home
Check pressure switch, tank precharge, and pump output
Could be: undersized pressure switch, partially failed pump impeller, clogged well screen (common with FL sandy soil), low aquifer yield in drought conditions, or waterlogged tank. FL summer drought June–October can drop well yield significantly.
Urgency: MediumNeeds diagnosis
🔴 No Water / Pump Won't Prime
Emergency — call immediately
Pump failure, loss of prime (jet pump), burned motor winding (submersible), or broken pitless adapter. In FL lightning storms, pump motors are a common lightning strike casualty — surge protection is a must. Submersible pump replacement is a specialized job requiring well service equipment.
Urgency: EmergencyPossible motor failure
🌊 Sputtering / Air in Lines
Air entering suction side
Possible low water table (FL drought), broken well screen allowing air entry, or failing pitless adapter. FL's dry season (Nov–Apr) drops water table 3–8 feet in many areas, temporarily reducing pump yield and allowing air entry. Often resolves with rain but should be inspected.
Urgency: ModerateSeasonal or structural
🧪 FL Well Water Quality Checker
Florida well water ranges from excellent to severely contaminated depending on region and aquifer. Select the symptoms you're experiencing for a likely diagnosis and treatment recommendation.
🟤 Red/brown staining on sinks, toilets, laundryHigh iron content — extremely common in FL Floridan aquifer wells. North/Central FL especially affected.
💨 Rotten egg smell (hydrogen sulfide)H2S gas from anaerobic bacteria in aquifer. Very common in FL — especially Sarasota, Charlotte, Lee, and Manatee counties. Offensive but often not harmful at low levels.
🪨 Mineral scaling / white deposits on fixturesHard water from dissolved calcium and magnesium. FL Floridan aquifer: 200–400+ mg/L hardness is typical — very hard. South FL surficial: moderately hard.
🍵 Tea-colored / yellowish waterTannins — organic compounds from decaying plant material in shallow FL wells. Very common in North FL (Alachua, Columbia, Bradford counties). Not harmful, but stains laundry and tastes earthy.
🦠 Recent flooding near well / after hurricaneColiform bacteria contamination risk after FL flooding. Hurricane flooding can breach well casings. Immediate water testing required — do not drink untested well water after flooding.
🌊 Salty or brackish tasteSaltwater intrusion — critical issue in coastal FL (Miami-Dade, Broward, Palm Beach, Lee, Collier). As FL sea levels rise, saltwater intrusion into shallow aquifers is increasing. Reverse osmosis or water source change may be required.
🌫️ Cloudy / turbid waterSand, silt, or sediment in FL well — often indicates failing well screen or collapsed borehole. FL's sandy soil is particularly prone to screen clogging. May require well rehabilitation or screen replacement.
🧪 Concerned about arsenic / contaminantsFL has some arsenic-elevated areas, especially along paleo-river systems. Also relevant: PFAS contamination near military bases (Pensacola, Eglin AFB area). Test water if in high-risk area.
🔵 Blue/green staining on copper pipes or fixturesLow pH / acidic water corroding copper. Common in shallow FL wells. Pinhole leaks in copper pipes accelerate. Whole-house acid neutralizer (calcite filter) is the standard treatment.

- Floridan Aquifer System: largest artesian aquifer in SE United States, underlies most of FL
* Depth: 50–2,000 ft depending on location
* Water quality: hard (200–600 mg/L hardness), may have H2S, often artesian pressure
* Best water yield: central FL — 100–10,000 GPM possible
* Coverage: statewide except extreme SE FL
- Surficial Aquifer System: sandy, unconfined, water table aquifer
* Depth: 5–100 ft
* Water quality: soft to moderately hard, may have tannins, iron, coliform risk
* Coverage: all of FL, primary source in SE FL (Biscayne Aquifer)
* SE FL Biscayne Aquifer: shallow (0–25 ft), high yield, saltwater intrusion risk
- Intermediate Aquifer System: West-Central FL only (Sarasota to Tampa area)
* Provides isolation between surficial and Floridan aquifers
FL WELL DEPTH GUIDELINES:
- Shallow jet pump systems: static water level must be within 25 ft of surface
- Submersible pump sizing: match to static water level + friction loss + pressure requirement
- Minimum FL well casing depth: 20 ft in surficial aquifer, varies by county

- FL well setback requirements: 75 ft from septic drain field, 50 ft from septic tank, 10 ft from property line, 25 ft from drainage ditches
FL PUMP SIZING GUIDE:
Residential demand (GPD): 75 gallons/person/day × household size
Peak demand: typically 2–3× average daily demand for sizing
Standard FL residential: 1/2 HP pump for 3–5 GPM (1–2 people, shallow)
Typical FL household: 3/4–1 HP pump for 8–12 GPM (3–4 people, medium depth)
Irrigation + house: 1.5–2 HP for 15–25 GPM combined
Pressure setting: 30/50 PSI standard, 40/60 for multi-story
PRESSURE TANK SIZING FORMULA:
Drawdown needed = GPM × 60 / (cycles per hour)
Tank size = Drawdown × pressure ratio factor (varies by pressure setting)
30/50 PSI factor: multiply drawdown × 3.6
40/60 PSI factor: multiply drawdown × 4.1
Example: 10 GPM pump, 8 cycles/hr, 30/50 PSI
Drawdown = 10 × 60 / 8 = 75 gallons
Tank size = 75 × 3.6 = 270 gallons (minimum) — round up to next standard size
