Ever built a black tank cleaning wand?

Before I knew you could buy them I made one from 1/2" copper pipe.
I already had a shut-off valve that screws on the end of a garden hose. For the wand itself I bought a female hose to 1/2" threaded pipe adapter and a 1/2" copper to 1/2" threaded adapter. I capped off the other end of the pipe and cross-drilled 1/4" holes 90 degrees apart.

I made one. No pic. 4' section of 3/4" pvc. End cap on one end with 6, 1/8" holes drilled around the cap alternating pointing straight out and slightly down and 1 in the middle. On the other end was a fitting with a hose connection. I sometimes use it, but mostly relie on the Black tank rinser on this MH.
