thanks . . . .
if your tank flush unit is mounted into your tank on the street side, as most if not all are, consider this: ... it is mounted on the drain side, probably just above the drain valve(that's where mine is), ... the flush unit sprays water into the tank, so, IF you "spray while draining", you are spraying water into/against the flow of water and solids trying to flow out the drain, ... thus hindering that flow, ...
for a long time, I assumed the flush unit would be mounted on the curb side of the tank and over there would actually be spraying in the direction to help push the stuff towards the drain, but that's not the case, .... our first two trailers didn't come with a factory flush unit so I installed an after market tank flush system, the "quickie flush", on both and mounted them on the curb side because to me that is where it should be installed, trailer #3 came with the flush unit installed and I thought that was going to be great, ..... I used it the same way until I discovered it's mounted just above the drain valve on the street side of the tank, ... now I spray as much as I want to spray and then turn off the spray before opening the dump valve, I then open the dump valve and let the tank dump without spraying water into that flow trying to leave the tank, ...
you will need to search to find where the unit is installed into the tank, but more than likely it is on the street/drain side,...... its easier for FR to put it there, than to run a line over to the curb side and it does work from there , it just works better if you don't spray while dumping, ......
