You blew out the lines, ran pink antifreeze at every faucet, and bypassed the water heater. Good. These four spots still catch people, and they’re the ones that show up as leaks in spring:
- Outdoor shower. It’s on its own branch and easy to forget. Open it and run it until you see pink.
- Ice-maker water valve. If your fridge has an ice maker, the valve holds water and can crack. Check your fridge manual for the winterizing steps.
- Toilet sprayer. It’s a separate line off the toilet’s water supply. Squeeze it until pink comes out.
- Washer drain pump. If your rig has a washer, the pump and its lines hold water that can freeze. Many owners miss this one.
Quick test: if your rig has any of these and you didn’t run or drain it, it isn’t fully winterized.
