Understanding What an RV Low Point Drain Valve Is

When I first started looking into RV maintenance, I quickly realized how important the low point drain valve is.

Installing the valve was straightforward, but I made sure to turn off the water supply completely first. I drained the system as much as possible, then removed the old valve carefully. When installing the new one, I used plumber’s tape on the threads to ensure a tight, leak-free seal. After installation, I tested the valve by filling the system and then draining it to check for leaks.

Maintenance and Longevity

To keep my valve working well, I regularly check it for cracks or leaks, especially before winterizing. Occasionally, I clean the valve to prevent debris buildup. If I notice any stiffness or dripping, I address it immediately to avoid bigger plumbing issues.
