Never read any of my posts on that have you.. I used a quarter inch hole in mine.. Been describing it on here for some time.
And by the way.. WORKS GREAT
Valterra makes one called the "Master Blaster" Roughly the same thing but i'm a bit concerned about hat nozzle they use.
And then there is one I think is called "The RV Twister" (not sure) has a brass spinner on the end.
Now if only I could use it on the gray tank.
Home is where I park it!
