Historically, these preventative measures were developed through experience and observation of the detrimental effects of winter weather on early camping vehicles.
The subsequent sections will detail the specific steps involved in preparing a recreational vehicle for winter. This will include draining water lines, adding antifreeze, disconnecting the battery, and addressing other essential areas to mitigate potential cold-weather-related issues. The following information provides a systematic approach to ensuring the longevity and functionality of the recreational vehicle.
1. Drain water system
Effective drainage of the water system is a foundational element within the overall process of preparing a recreational vehicle for winter storage. This procedure aims to eliminate residual water from pipes, tanks, and fixtures, preventing potential damage from freezing and expansion during cold weather conditions.
-
Elimination of Water Sources
The primary objective is to remove all standing water. This includes emptying fresh water, gray water, and black water tanks. Failure to completely drain these tanks can result in cracking or bursting when water freezes and expands. Drain valves should be opened and tanks allowed to fully empty. This also includes draining the water heater.
-
Bypassing the Water Heater
Most recreational vehicles are equipped with a bypass valve for the water heater. Prior to draining the water heater, the bypass valve should be activated. This prevents antifreeze from entering the water heater tank when the plumbing system is subsequently winterized, conserving antifreeze and preventing potential damage to the water heater’s internal components.
-
Opening All Faucets and Low Point Drains
After draining the tanks and bypassing the water heater, all faucets (both hot and cold) and low point drain valves must be opened. This allows any remaining water trapped within the plumbing lines to escape. Leaving faucets open also prevents vacuum lock, facilitating complete drainage.
-
Utilizing Air Pressure
To ensure complete water removal, compressed air can be used to blow out the remaining water from the plumbing lines. A special adapter connected to a compressed air source can be attached to the city water inlet. With all faucets and drains open, low pressure air is introduced into the system, forcing any remaining water out. Caution must be exercised to avoid over-pressurizing the system, typically keeping the air pressure below 40 PSI.
The thoroughness of the water system drainage directly correlates with the effectiveness of the overall preparation strategy for cold weather. Incomplete drainage can negate other preventative measures, leading to significant damage despite efforts in other areas. This critical step ensures the long-term integrity of the plumbing system.
