Fresh water drain plug sticks
The fresh water drain petcock on my trailer is very hard to turn. Is there anything I can use to lube it? Is silicone oil ok for plastic?

Not familiar with the PVC type petcock on A/S, but on the pool at my old house, I used to use baby oil on the PVC valves for the solar panels. Worked like a charm.

Yea mine is a bear also. The problem is getting it started since the little tab sits against a flat surface. There is no easy way to get your finger behind the tab. Sometime a small screwdriver just to pry the tab away far enough is all you need to do. Once you get your finger behind the tab you can apply the force necessary to open it up. I haven't had to take the lubrication route at this point.

On the '03s (at least the Bambi), those type valves are gone. They use a smaller version of the valve that connects to a house toilet, except these move very, very smoothly. No binding at all.

Mine has a PVC ball valve. There is an elbow and the ball valve hangs right under the tank woth a big handle. Very easy to operate, but I worry sometimes about it hanging so low.

nylon
skip
as near as i can tell it is made from nylon.
i used silicone dielectric grease on mine.
if you push up on the bottom while turning it pops up. then you can remove the core.
plain corn oil might work also.

Strange. I answered a question on another thread and it ended up on this thread instead. I had a line drop while answering and that might explain it.
Sorry, I didn't mean to confuse the issue..

I'm sorry I didn't describe the problem clearly enough. The petcock I'm talking about is the one under the trailer to drain the fresh water tank for winterizing etc.
Sorry,
SkipJ

Well, 6 years have gone by and SkipJ's question seems to have been not fully answered...
And my fresh water drain petcock did not want to budge when I tried to open it with my hand, and I don't want to break it so...
Does anyone have any updates, hints and/or ideas re: this problem?

it looks answered from my reading.
the wings on the nylon petcock are very strong.
once thought i'd break it too, but did not.
as jack notes in THIS thread 6 years ago...
the main issue is turning it TOO FAR (open or closed) so that a finger won't fit behind it.

and as john suggests, one may use dielectric silicone grease for lube.
i use food grade silicone spray which penetrates the mechanism, making turns easier.
silicone (siloxanes) are not OIL, but they are sometimes put in an oily substrate.
some of the 100% silicone sprays indicate on the label "safe for nylon or plastic"
and food grade is even better around the galley and water supply.
and just remember NOT to turn too far.
as soon as the flow stops it's closed, and full open is about 45 degrees .
here's an old post on this, i use the SAME spray on window gaskets and door gasket and the FRIDGE gaskets....
http://www.airforums.com/forums/602814-post4.html
the stuff a/s uses is made by dow "316" and that's what i use because it's food grade.
cheers

After many painful fingers, different lubricants, and extensions to increase torque, I had AS replace it when we were last in JC - works pretty smoothly now.

The stuff is now called Molykote 316 and seemed to help.
Details on this and my experience are here.

Not really related to the lube issue, but I found mine was very hard to access between the wheels, so I added a length of hose to the spigot, ran it to a second tap which I installed on a new bracket just ahead of the lead wheel. So now I leave the original tap on the open position.
The only slight concern I have is that the new valve is a bit more vulnerable to damage from road debris, but if it gets knocked off, all I lose is water plus a $4 valve!
It is much easier to get to!
