neilp Posted March 29, 2022 Share Posted March 29, 2022 My camper has leaking low point drain valves - the ones under the couch that pull up to drain the fresh water tank and the lines. When I first got my camper 3 years ago I replaced the other two that are under the stove area with different ones which was a big job with shark bit fittings etc. I have since read about replacing the o-rings but I'm not sure how thevalves come apart? I recall that you remove the metal loop and push them through the floor? I've searched the forum and the net but cannot find the answer!

neilp Posted March 29, 2022 Author Share Posted March 29, 2022 Also if anyone has the sizes of the required o-rings that would be awesome! Quote Link to comment Share on other sites More sharing options...
neilp Posted March 29, 2022 Author Share Posted March 29, 2022 I just tried pushing one down and popped out under the camper very easily. However I should have thought to release the water pressure first!! I'm off in search of o-rings now so any advice on the size is still appreciated.

neilp Posted March 31, 2022 Author Share Posted March 31, 2022 Quick update: I tried the closest sized o-rings that were at Home Depot. No good, the "plunger" piece would not go back into the valve body no matter how hard I tried. The new o-rings are only a gnat's bollock hair bigger than the originals but that seems to be sufficient to stop them from working. So I did my best to reinvigorate the original o-rings with hot water to make them usable and reassembled the valve. After practicing a few cuss words I found that the reassembled valve now worked in reverse - down is sealed and up is draining. A bit baffling but I'll take it as it no longer leaks.

linda s Posted March 31, 2022 Share Posted March 31, 2022 I find Home Depot's assortment of O rings to be limited. I always hit Ace Hardware for those. Linda S Quote Link to comment Share on other sites More sharing options...
Legobusier Posted March 31, 2022 Share Posted March 31, 2022 (edited) If you have a Harbor Freight nearby, they sell a reasonably complete "O ring" assorted kit for cheap (it IS Harbor Freight after all). Not sure if they have the size you're looking for but it might be worth giving it a shot. For example: https://www.harborfreight.com/382-piece-o-ring-assortment-67554.html Edited March 31, 2022 by Legobusier Quote Link to comment Share on other sites More sharing options...
Maineah Posted March 31, 2022 Share Posted March 31, 2022 Any auto parts store will have an assortment of "O" rings. Quote Link to comment Share on other sites More sharing options...
