Nắp chụp cổng anode cho máy nước nóng RV

This is a threaded plug that is designed to fit in the anode port of a Suburban brand hot water heater commonly found in RVs and travel trailers. The plug has a grid-shaped vent to allow for airflow into and out of the water heater promoting evaporation and preventing mold and mildew during storage.

When an RV is “winterized” or prepared for storage over the winter, especially in a climate with sub-freezing temperatures, the water heater is usually drained and the anode rod is removed. However, if you just leave the rod out of the water heater, then there's a chance that insects or other debris may gather inside the hot water heater during the off-season. This plug prevents that from happening while still allowing airflow.

This is not intended to be used while the water heater is in operation. That wouldn't even work. If you filled up the water heater with water, it would just leak out of the holes in this cap. You'd have no hot water, and you'd likely destroy the electric heating element in your water heater. This cap is for stored, winterized units only. When you install it, just hand-tighten it. No need to use a wrench.

Print it flat side down. No supports or anything needed. I used PLA. You can use whatever. It's not weight-bearing or exposed to UV light with the water heater cover in place.
