Another consideration. I recently had to replace the blade valve to my black tank. I started to remove the end cap prior to connecting the hose and had some brown water leak out. (always remove that cap slowly) I was able to get a container under there before removing the cap. Both valves were closed but obviously the black tank valve was leaking.
I drained and flushed the tank 3+ times and removed the bladevalve. The end of the blade and the gasket were damaged by excess hard yellow glue used to put the plastic pipes together. A new blade valve (+- $10) comes with the gaskets and if you need to work in there you might as well replace the whole thing.
Had the 2 previous RV's for 12 & 16 years, 1st valve I've replaced....

Remove the bottom plate 1st, and if you suspect a leak have a container beneath the opening when you crack the cap/cover. The small cap on the cover is a hose fitting.
