I connected my swamp cooler to the the test port on my FEBCO 765 backflow preventer. It has a 1/4 flare connection. When I was buying parts the "resident plumbing expert" kept telling me it was the "last thing I'd ever want to do". He didn't have an reason, so I marched ahead. Is this bad?
Here is the manual:

I connected it to testcock#1 (before the seal breaker). I did this because the swamp cooler is 20' higher than the backflow preventer, so it would not prevent backflow properly. I figure it is the same as installing a TEE before the BF, but less work.
He also insisted the test ports were drain valves, so I felt OK disregarding. But, I do prefer to do things right, not a DIY hack. So, am I OK?
Thanks.
