Water Heater Intake Line dripping

Question...

Noticed a slight "drip" coming from the intake line of my water heater, inside the RV. It's Pex tubing to a "screw type" fitting and then to the water heater. Tightened the fitting before winterizing and THOUGHT I took care of it; the leak seemed to stop.

Just checked out the trailer from a long winters nap and found some antifreeze in a little cup I put under that fitting so apparently, my fix didn't work too well.

Before I go draining the antifreeze and unscrewing the fitting, is there anything I need to know? Is there some sort of "gasket" under that fitting that may need to be replaced or do they use Teflon tape to seal it? I just don't want any major headaches since I've never taken one apart before.

It's only dripping from the "in" line (cold)

Thanks in advance!

  • Ok. Thanks for the replies. Sounds like a somewhat easy fix then. Supposed to tickle 70 degrees this week. Might be time to give it a look. Only 27 more days until she gets dragged to the seasonal site! FINALLY!!

    Thanks again!

    Check washer for tears/gouges/nits.
    Replace if any signs of damage.

    Replacement packs of washers available at Home Depot/Lowes/Aces etc.
    Could be flat, tapered, coned based on type of fittings the nut screws onto
