Leaky Dump Valve

[Bruce Ebling]

Noticed my waste dump valve leaking on my 21' RB Bigfoot. I looked underneath to attempt a repair and found all plumbing is concealed by a underside pan. Has anyone replaced or repaired the dump valves on their Bigfoot trailer? Any advice would be helpful.
Thanks

I haven't seen your valve or your trailer, but a common dump valve is glued to the drain line.
The good news is that there are four screws on the flange so the valve can be disassembled. You could clean it but it is easier to buy a new valve and disassemble it. Reassemble using all the new parts except the inlet side which you can just clean. A little care must be taken with the rubber o ring. Use a little silicone grease for assembly lube. This is a simple repair which can avoid cutting and gluing.
All this assumes that the valve looks like this...

: changing that valve to a new one was the easiest job my wife ever did, she just made sure the tank was empty first or there would of been one heck of mess.
also we have easy access as no laying on back when doing the work.
