I completed the steps to replace the air gap in the water heater as outlined in the post from pulsar .
I turned the water heater back on when complete for about 15 minutes and water dripped out of the relief valve again once the water heated up.
A few days ago, when I first noticed the water dripping down the outside of the motorhome, I opened the water heater access panel and found a small plastic orange sleeve laying in the bottom of the water heater panel area. See the photo below.
What is it and where did it come from?
