Fw Drain issue

[DocData757]

Went to put FW in the tanks today for the first time after having a water outage in the park yesterday. Started filling and found it was all running back out of an apparent drain pipe.

What i need to know before I fix this is... am I just missing the drain cap or is there a valve supposed to be there. For that matter, is there a valve already there but above the false floor down there?

This line (see photo) is on the left side of the camper just in front of the tires about a foot.

Mine has a drain cap. No valve.

Yup, that is the drain for the fresh water tank. There is no hidden valve, it is just a piece of plastic pipe with a cap on the end. There are actually two pieces to the cap, the white cap itself, and a white rubber gasket that fits inside the cap.

Any RV parts counter should be able to replace it for you. It is just a standard PEX fitting.

There should be two more of those pipes and caps hanging down under the trailer. They are the low point drains for the hot and cold water. They should be identical to the missing one on your fresh water tank. If need be, you could borrow one of those caps to take to the RV shop to show them what you need.

Or you may find it lying the ground somewhere.

The low point drains have no caps and nothing to screw them on to anyway.

The tank drain's gasket is still there just no cap. Going to the RV store at lunch.

Thanks all!

DocData757, Howdy;

They (the caps), are cheaper at your local hardware store... PEX is not RV specific.

Hmmm. My Cougar has the same cap for all three drains: hot & cold low point and the fresh water tank. I wonder if your rig has valves inside?

I've looked in several big box and smaller hardware stores; not everyone carries them, but certainly worth a looksee if the RV shop is further away. What I am finding is more PEX to copper or brass fittings these days, and a lot less of the plastic PEX fittings. But every place is different.

[DocData757]

Sorry. I did not mention that both the low point drains have valves up in the convenience center compartment.

Be careful on the cap you buy. I notice on my Cougar MKS 326 the low point drain caps are different than the fresh water cap. I don't know if this is particular to my trailer or not. The caps on the low point drain are more V shaped and the fresh water cap is squared off. Jay
