Suction Side Air and leak

[lcrooks]

One more question before I dig. I came across a page somewhere on the internets where it was advised if you have a robot, you can just abandon the main drain period. The robot run religiously will circulate enough from the bottom.

Good idea, bad idea?

The robot will provide some extra circulation for your deep end. Is it a good substitute for the MD, but a designated line to pull that lower water is better. (JMO) There are other options, I mentioned 1 of them in my earlier post (about the 'reserve line). It helps to have the water in the deep end moving around - the robot will 'at least' stir things up down there.

Let us know a little more about the 'suction/ return' system on your pool - another idea might just come

I have just a main drain in deep end, skimmer also located on side in deep end. Two return lines, one 3/4 way down on long side, the other located just before the curve on the end straightens out, opposite of the 1st return line.
