Hard plumming chiller Question with pic's

corals b 4 bills · 04/15/2008, 10:54 AM

So I wanted to install a water changing drain from my tank to my sewer clean-out in my garage to make life a little easier when it came time to do water changes, I figured that at the same time I would hard plumb my chiller, well of course as luck would have it I am sucking air in somewhere and I can't find it. If I was on a job I would find something to use (Soap or what-not) but in an environment like this how can I find the leak? I am feeding the chiller with a mag 18, in the pictures below the pipe on the left is the water inlet from the tank to the chiller, the right is the outlet from the chiller to the Mag, the horizontal one is the water changing drain (gravity fed) I put two ball valves on this one to prevent cross contamination. If you have some ways to find the vacuum point that would be great thank's, Mark (Are unions prone to sucking air? I have 5 of them).

I use the same valves with no problem. IMO if they suck air then you would have a water leak there also. I would assume the air is coming from your tank or overflow and would try to purge water through it or maybe your water level is low in your tank.
