Black/gray drain Belt and Suspenders

After seeing the results of what happens if the brackets for either the black or gray water tank drains fails, I decided to invest in a little preventative measure. I call this "belt and suspenders", as if one bracket fails, there will be a second "just in case". 

The parts I used are all stainless except for the clevis hangars, which are epoxy coated. I could have used stainless clevis hangars, but the 3" one is $5 in epoxy coated, and $30 in stainless. In this particular instance, I chose overkill instead of massive overkill.

All of the nuts are stainless nylock nuts.

Got them from Ferguson (https://www.ferguson.com/product/fnw-epoxy-plated-adjustable-long-drop-clevis-hanger-fnw7006ep/_/A-ProdFamily-133824)

Remember, these hangars go by the ID of the pipe (not the OD). So the 3-1/2" (OD) black water pipe is actually a 3" (ID) hangar.
