dump valves
My black tank dump valve is really hard to open and close now. How can I service it? I hope I don't have to remove it. Thanks

Changing the blade is relatively easy. Remember, you DO NOT change the whole valve, just the blade. 4 bolts, two gaskets and a lot of plumbers grease. Drain and thoroughly flush the tank. Then unbolt the blade assembly, pull the two halves apart, slide the old blade assembly out. Clean the mating surfaces, grease liberaly, and install the new blade assy. Be careful to tighten the four bolts evenly. Otherwise you will have a leak. And dont over tighten them either. Once done, test by dumping 5 to 10 gallons of water in the tank and check for leaks.
