I had the neighbor install a new plastic outside knob a couple of years ago and it worked great. This is the knob/outside faucet thingie to drain the holding tank when needing water for boondocking. However this yr, the plastic is already hard to turn and is breaking the knob off again. The neighbor has moved, and I need a perminent solution this time.
Do you all just replace that knob every 2 yrs??
Is ther some type of a metal knob solution???
This is the worst thing I have found in my Scamp and Casita so far. These knobs just seem to break when turning.
thanks

How about adapting some kind of household plumbing globe or gate valve?

Maybe something like this?

My Burro has something like this mounted to a aluminum plate that screws to the floor.

Also known as radiator drain cocks the link is just for reference I've seen them for $2.00 check the auto parts places too.
See if you can invent something to work for you.

I'd start with an NPT (national pipe thread) / barb connector to go on the hose that's connected to the water tank.
picture found here

On the outside, I'd just use a standard garden hose bib. You should be able to find the NPT/barb connector that will fit both. After that, you can rivet the brass hose bib to the side of the camper. The only fear I would have is that if it caught on something, the fiberglass would break before it did.

this is the thing that is rotting out again. I can not get the picture to show up, but maybe by seeing this you will understand better what I am looking to replace.

I know exactly what doohickey you're referring to, I had to replace mine this summer as well. The picture that I directed you to is just an adapter that would allow you to use something completely different to replace the plastic thing.

You'll still have to drill out the rivets, and remove the plastic one. Then you'll need to disconnect the plastic line from inside to make it easier to work on.

Hang on.... I'll see if I can get pics to explain. Back later.

Alright, let's see if I can make this work with images pilfered from the net...

The idea I have is to replace this;

It would certainly outlast any little plastic bit.

Karalyn,

The photo in Paul's post is probably what you have. If that's the case, you should service the valve at least annually.

To do that, pull up on the handle with a pair of pliers (cushion with a piece of cloth) and the shaft whould pull right out. Coat the shaft with petroleum jelly (Vaseline) and re-insert it.

Mine was held in with a hoseclamp, so a little surgery was required. If I only get a couple of years out of the replacement, then I'll go with the setup I described above, and right beside it I'll have another tap for pressurized water. Then again, I may do something else altogether depending on my mood at the time.

Back to the original problem: You'll likely have to drill out the existing rivets if you are going to use another of those plastic valves. Since I don't know how mechanical you are, I'll just say that this is a simple little project that is only frustrating because of the tight quarters that may be involved. I'd try to tackle it myself first, as long as you aren't using a crowbar to pry on things you can't make them any worse.

Ours became brittle and fragile also. After installing a new one, I then cut the plastic drain line and inserted a plastic ball valve using 2 of the barbed fittings. The Casita has a locked access door in just the right location for access to the ball valve. Now we simple leave the replaced valve open all the time and control the flow with the ball valve. This will also prevent some mischievous youngster from draining the water by "accident", and even if the exposed valve becomes damaged our water system will still be functional.

I have the same problem: one half the handle broke off last year and the other half followed this year. I'm reading the variou solutions to the problem with interest. Thanks for bringing it up, Karalyn.

Don't know what the original looks like, but could you install a brass valve in its place?
