Brass valve rebuild

Learned a LOT over the past two weeks! The original brass valve on my 61 Tradewind leaked. I have all the fittings (sewer hose, gray water adapter) so kind of wanted to keep it. Figured out that the lower half adapter just screws on (took about an hour to get it off), leaving the guillotine valve attached to the bottom of the BW tank. The screws were rusted to badly could not get them off. Cut the heads off and it popped right off - was able to easily turn the screw spindles out the tank fittings. The other set of bolts holding the two halves of the valve were also pretty much fused, so drilled those out. At that point, had the two halves and the valve slide, and a broken 53 year old O ring. I polished the slide, cleaned up the rest and went in search of an O ring. Ended up at Graybar Supply. A parts guy looked at it, walked to the back and came out with the exact O ring, free of charge. Wow. Installed it, used a little silicone grease, put the two halves back together using stainless steel bolts on the halves and it all seemed to work well. Ran a bead of silicone on top, bolted it back on and let the silicone cure. Crossed my fingers and poured a quart of water into the black tank. No drips. Added another two quarts and let it sit with a newspaper underneath - no leaks. Opened the slide, worked great! Put the belly pan back up around the valve and I was set! That is until I realized I forgot to reattach the valve extension handle so I can open it! Oh well, always something! Will wait until next week to redrop that section of bellypan. Main lesson - those valves are made to last as long as the trailer - no comparison to the plastic ones today. Glad the repair worked!

I love pulling apart old plumbing and fixing it. it's a great feeling when the rebuild is probably better than new, costs next to nothing and is better than anything you can buy today.
