Low Point Drain Shut-Off Valves
I have a similar setup, just 2 screw-on caps on my low point drain hoses. Has anyone added shutoff valves? I am trying to find some that just screw onto the drain hoses and then use the existing caps at the bottom of the valves to seal the openings. I haven't been able to find any of that type on any website (the ones I find are either clamp-on, angled, or the wrong size). My idea is similar to the ones on the picture, except that the valves should be at the ends of the hoses w/o extensions. I have checked several RV websites and Amazon, but no luck so far!
