Summary

Cold snaps can catch RV owners off guard, so this job focused on preparing a coach for winter storage before freezing temperatures arrived. The owner requested a full preventative winterization service to protect all water systems from freeze damage while the RV sat unused.

The Work

Drained the freshwater tank, water heater, and all low-point lines
Pressurized the system with air to clear out water from supply lines
Pumped non-toxic RV antifreeze through every hot and cold fixture, including sinks, shower, toilet, and outdoor spray port
Charged all P-traps and covered the toilet bowl seal with antifreeze
Checked and secured all access points and returned keys to the lockbox as directed

The Outcome

The RV's entire water system now has reliable freeze protection, with antifreeze visible at every fixture and drain. The owner can store the vehicle with less worry about freeze-related plumbing failures over the winter.
