Just installed a “freeze proof silcock” in my cabin, 7200’. Indeed, the valve stop is way back in the extended pipe several inches in length depending on your climate, protected by a warmer temp. The idea is for the unit to be installed with a slight tilt down, back towards the supply line. My process is to turn off the entire supply to the house, which has a stop waste valve 40” underground, and then open the silcock to drain any residual water. Short story made long, I don’t think it’s the solution you’re looking for in a camper but as always, YMMV.

Oh dang, that flange on Ebay is no longer available.

[craig333]

There are other sellers on ebay.

I just ordered the parts, figured I'd elaborate on what the latest that's available is. The flange I got was from ebay, there are quite a few available. The one got was USA made from a veteran owned business and was linked previously:

Description:

 

This Company Is Operated By A 100% Disabled Marine Corps, Combat Engineer Veteran...

 

This is a very High Quality, RV Fresh Water Supply Drain Valve Flange.

 

Attention Air Stream Owners!!!

 

This listing in for one (1) Drain Valve Flange Only...

"The 1/8 NPT Brass Valve Is Not Included In This Listing."

It's pictured only for illustration purposes, but can be purchased at most any automotive parts store, as it's an Eaton 1/8" NPT traditional drain valve, designed for older vehicles.

 

This is now, only available in anodized black!!!

 

This product was designed & built by a master machinist that was tired of replacing cheap, imported plastic mass production drain valves, that are designed to fail...They do not stand up to direct sunlight or harsh elements and require continual replacement.

 

This drain flange is CNC machined from a solid piece of High Quality 6061 T6 Aluminum and is designed to accept 3/8" or 1/2" drain lines, as there is approximately .0075 clearance on each side of the aluminum barbs, for easy insertion and clamping, to the 3/8" or 1/2" poly tubing.  And best of all, they are made here in the USA!!!  The drain flange was also machined to accept any 1/8 NPT thread drain valve.  We suggest brass or a quality valve that will not become brittle and crack, as most cheap drain flanges do...The standard color is anodized black...

 

The mounting hole spacing, is 1.50" center to center, just as the plastic drain flange is.  We advise purchasing the flange in anodized black, as that eliminates the possibility of any possible oxidation down the road.

                   

 

With proper winterization, this is the last drain valve flange you will ever buy!!!

 

 

 

The valve I got was also linked previously and is a LASCO 17-0939. Available in many different places but I used Amazon.

My solution to the cheap broken plastic drain valve is similar to Gaylon's. I bought the same flange he did on eBay <http://www.ebay.com/itm/181845510888>. It's pricey but well made and the mounting holes are the same as the old valve. When I unscrewed the old valve from the back camper wall I was able to pull out enough of the plastic drain hose to clamp with my little Vise Grips and then install  the new flange.

 

I did get the petcock valve as recommended (see pictures) but have found I like the brass plug better. No worry about breaking it off and water flows out faster than with the petcock. I don't drain the tank often so all in all I like the new setup.

 

I did the same thing!

This setup works perfectly for me. Only sticks out 1.5". Smooth action on ball valve.
