I would think the small drain as the majority here have stated having (and which I also have) is probably a safety feature - think about the traffic behind you if a larger valve all of a sudden worked loose while you are on the highway.

On my TT drain, I often found algae growing at the valve. I used a piece of about 16 gauge stranded, insulated electrical wire to snake it out. Open the valve and insert the wire. Usually the clog is right at the valve. You'll immediately know if this works or not!

A 2 1/4" to 2 1/2" knife drain is normal and doesn't take long. Anything less is substandard and just plain cheap.


My Springdale must be a cheap POS since it only has maybe a 1/2" drain tube. Takes at least 30-45 minutes to drain.

You might also want to check the drain for left over sawdust and construction material. My 2014 Enterra never had the water tank used. always on city water with the last owner. The first couple times I tried to drain it I had to push a coat hanger up into the drain. You wont believe how much junk is left in the tanks from the factory.

I did a youtube video on de-winterizing and sanitizing your RV water system. Maybe it will help you out to familiarize yourself with the RV water system, also shows my high flow fresh water drain for the OP ๐Ÿ™‚ de-winterizing video

So far..... this is the best answer.

Generally I do the bleach thing then dump the hot water tank and replug. Then I open the low drain points and go to dinner, or cut the grass or play with the wife. After hooking up I put in 5 gallons if we are just using the water for the bath but if it is for drinking I wait till I can use my white hose at a fill station. No big deal either way. and if I am looking to winterize I just open the drains and all the taps and drive home. Doing this stuff for 40 years so it's automatic.
