Based on the long thread started by KirbyRVA and the recent work I did to move my black tank flush, I thought I'd try to figure out a baseline for my system and (hopefully) get a few more to compare (from all of you).
The testing methodology is far from "scientific", but I think with enough information we can draw some general conclusions.
What I did was hook up a 50' hose to my house and then to the black water inlet. The black tank was empty, and knife and add-on Valterra valve were both open (and left open). No drain hose as I knew the tank was clean.
The pressure gauge showed ~50 psi at the black water flush inlet (no regulator in the line). Note the hose is connected to my home's system at a spot quite distant from the actual house as the spigot was added to a shed for the camper. (Easily 100' of pex running underground from the house to the shed.)
I then turned on the water for a minute (with the volume meter recording the flow). Pressure dropped during the test to ~20 psi.
I ran the test three times. The results on the volume meter were 2.4, 2.5 and 2.5 gallons in the 1 minute time period.
So there you have it. How about yours?
