What are these valves and why is one dripping.

When filling my testing my hot water and running the cold water, I noticed water dripping from this valves to what I think is the grey water holding tank. About 45 minutes later the water drips were gone and is now dry. Any idea what those calves are and why it would drip/leak and then stop?

They look like nice fresh water drain valves. Ball valves shouldn't leak. My '99 has 2 petcock valves for drains... just like car radiators.

They may well be your water pipe system low point drain vaves - one for hot, one for cold.

I have a 2015,16 ft and have determined they are a low point drain. But not exactly sure what they are draining. The freshwater drain is located upfront on the roadside. I don't recall them being identified in the owners manual. Perhaps someone can clear this up for us.

They are the low point drains for the plumbing, for winterizing.. The other drain Ron A mentions is for the fresh water tank.

Was it leaking from the stem? If yes, then the packing around the stem inside the valve probably dried out and shrank, and once water pressure was applied, it swelled up again and re-established the seal. Might be an o-ring instead of packing, but same net result. Keep an eye on it. If you notice it dripping again, time to take it apart and replace the stem seal. Or just replace the valve.

Also note that those valves are subject to freeze damage if not winterized/drained.

Those are your low point drain valves. The one on the left in the picture is likely your hot water and the other is the cold. If they drip from the opening, open and close the valve a few times and then leave it closed. Often, there is road grit, etc. that gets in the valve and may prevent a seal. When you winterize, leave them open. If the valve is left open, it is very unlikely that it will freeze. The PEX pipes that feed those valves run vertically from the 90į fitting on the near side of the valve in your picture. So the only moisture that can stay there is just in the part of the valve that you see. With the valve open, there is too little water for the expansion to split the valve.

I forgot the real reason why it drips. Cuz it can't go 'sniff'.

Bit off topic but Mel asked about Centramatics in Canada. You can phone Centramatics in Texas , they'll put you in touch with Pat Dolla in Quebec,
por15canada@gmail.com. Similar pricing give or take Cdn to US exchange and no customs/duty hassles.

Hello Mel,


I ordered them from "Inland Andy" in California. At the time I bought them I don't think they were available in Canada.

Brian. (Presently in Asheville NC on our way home from Florida! Put all new brake assemblies on our trailer when in Florida - much better brakes now! Should have done it sooner! Fixing up the ground connections surely helped too!)
