Annoying water leak/drip from drain tube

[FED565]

We have an older early 90's Jayco Eagle that has been a great trailer but I have had an annoying leak/drip coming from what I guess would be a drain tube from the back of the trailer (next to the sewage drain) when the water system is pressurized. We have had the trailer for over 5 years and it has always had this leak/drip but it has really gotten bad and wastes a lot of our water we take. I cannot trace it back as it is sealed where it exits from under the trailer. If the water system is pressurized it really leaks/drips good and if you open up the water faucets and un-pressurize the water system the drip from the tube pretty much stops.

I have asked numerous RV repair places about this and nobody seems to have any idea what could be causing this. Any ideas would be greatly appreciated.

thanks
Scott

I have asked numerous "RV repair professionals" on this issue and NONE of them could tell me even where to start looking.

Awesome forum.

And that is why I do my own repair work and frequent this site......

Both of my low point drains are a devil to operate. The stem pops up to open and down to close but they are in an awkward place and one really has to lean on them to get them to close.
Try not only leaning on the handle but rotate it slightly as you push. It should `click' into place.

Neither of mine are capped, I have valves on the interior of the trailer that I open to drain and close otherwise. Perhaps he has a defective valve on that low point drain... Easy enough to put a fitting on the end and cap it as a fix..

To the OP ... be aware that when some say "capped" they're probably referring to a female threaded cap but these low point drains can instead be "capped" with a male threaded plug, as they are on my own trailer.

Wow, thanks guys for the information. This is more info than I have got in 4 plus years of asking around. I will go home tonight and look for this stuff. Is there any issue with putting a cap on that drain?

Sure does sound like low point drains all right. The sharkbite fitting can be bought at hardware store and put on the pipe. Try opening and closing the existing valve and see if the leak stops(something on seal). It might be inside a cupboard right above the exposed lines if they are not exposed.

OK...yes, we are talking about low point drains. One is the hot water and the other is cold water.

There should be a cap of some sort on the end of each. If not, inside your trailer, in a cabinet, under a bench, or behind a removable panel there will be valves that open and close these tubes.

I am not sure if that is what they are. There are actually 2 of these tubes sticking out of the bottom of the trailer and only one is leaking. These are white plastic bendable tubing and not like plumbing PVC and probably 3/8 or 7/16 tubing.

Where would this Sharkbite valve be located? Is there a normal location for this?

Thanks for the response.

Is what is leaking one of your low point drains?
If so, try putting a new cap on it or even a new Sharkbite valve.
