What is this drain?

[jeffmx5]

First time winterizing the camper and I find the fresh water tank drain with a second hose next to it without a valve or cap. What is this, is it an overflow for the freshwater tank fill?

[northshore]

looks exactly like mine, one is the fresh water tank over flow the other with the valve is the fresh water tank drain valve

it looks exactly like my new Forest River, and I am going to cut both of them off and make them much shorter.
I'll reinstall the valve

Then your tank is not full it is being pressurized due to POOR venting

Fix your vent line......kinked, too long and has loop, not properly routed etc

Fresh water tanks have overflows, vent and fill

Looks like a Keystone 26RLS

Yes, fresh water tank is right above these hoses. Sounds like it is the overflow. Thanks all!

Looks like the water tank overflow/vent and tank drain.

What is located just above the lines ? Is your fresh water holding tank at that location ?

Duplicate message.

I would say it is most likely your fresh water tank overflow. All fresh water tanks must have them.
