ASLBPO | Type of Winterization

Types of Winterization
📌 There are three primary types of winterization: dry winterization, steam wet winterization, and radiant wet winterization, determined by the property's heating system.
♨️ Dry winterization is for forced hot air systems using a furnace and vents; steam wet winterization is for systems using a steam boiler feeding radiators.
💧 Radiant wet winterization applies to systems using a hot water boiler, which circulates water through radiators or tubing in floors/walls.
🔄 Re-winterization is performed if a previous winterization was compromised (e.g., in sinks or toilets) and only requires pouring antifreeze.

Standard Winterization Procedures
🛑 All winterizations require shutting off the main water supply, usually at the water meter or shut-off valve, which is then secured with a zip tie.
🔌 Electrical safety includes turning off the sub breakers and circuit breakers in the electrical panel box.
💨 All remaining water must be drained from the water heater, toilets, sinks, and plumbing lines using an air compressor.

Plumbing System Pressure Testing
✅ A pressure test must be performed using an air compressor to check the plumbing for leaks.
📈 A successful test shows a reading of 35 psi or more on the pressure meter, indicating no leaks are present.
📉 A reading less than 35 psi signals leaks; the reading taken at the outlet meter (not the tank meter) is the critical measurement for leak detection.
🛠️ Extensive damage, like broken copper pipes evident during a failed pressure test, may necessitate bidding for a plumbing inspection to determine exact repair costs.

Antifreeze Application and Final Steps
🧼 Non-toxic, pink antifreeze must be poured into all drains and the water heater to prevent ice formation and potential freeze damage during winter.
⚠️ Ensure the antifreeze used is color pink, as this indicates it is non-toxic; other colors may signify toxic chemicals.
🏷️ Winterization film tapes must be placed over sinks and toilets, and winterization notice stickers must be applied to all winterized components and the property's front door or window.
🔥 For wet heating systems (steam or radiant), the boiler and expansion tank must also be drained and winterized.

Key Points & Insights
➡️ Property preservation tasks are categorized based on the heating system type present (dry, steam, or radiant).
➡️ The standard pressure test threshold for a passing plumbing system inspection is $\ge 35$ psi.
➡️ Contractors must verify that pink antifreeze is used to ensure the chemical is non-toxic and effective against freezing.
➡️ Documentation is crucial, requiring zip-ties on shut-off valves and standardized winterization notices placed prominently on the property.
