Years ago I bought a Keystone Cabana used that was used as a hunting camp in the mountains of PA. The seller told me about the poonami and said the gray tank drained slow as well. He thought it may have been from puring the backun grease down the sink every morning. Ya think maybe that did it?

Anyway, I stopped at a self serve car wash in a small town and opened up the drain cal and looked in with a flashlight. It was a straight shot into the black tank and the gray tank was into the main line with a "Y". Couldn't be better.

After about an hour and $10 or so worth of quarters it was draining great. I swear I was hitting that change machine like a hot one armed bandit in Vegas. The amount of white chucks of grease from the gray tank was amazing.

And yes, I followed the clean outs from the car wash to the turn down that was in a sewer line and not a storm drain so the water was treated and did not end up in a stream.
