<p>you can see that i'm already planning to 'upsize' my outflow (.5" in -> .75" or 1" out)....guess i'll go with the 1" for faster draining. i can always downsize to smaller tubing if i need to slow down the cycle.</p>

<p>Exactly as TCLynx says. Always upsize gravity plumbing.</p>
<p> </p>
<p>I am filling my growbed with 3/8 ID tubing, and am having trouble draining it with 1" ID tubing.</p>
<p> </p>
<p>You will probably need to put in a bit of a restriction (smaller tubing) somewhere around the auto-siphon to get it to start correctly, but after the auto-siphon go overly-large. It's easier to downsize the first 2 feet than it is to upsize the whole run to the tank/sump.</p>

<p> </p>
<p>For a combined drain, I would move up to 2-3" depending on how many how big the grow beds are but that is just me, I build big systems. I suppose 1 1/2" pipe might work for a small run of combined drain.</p>
<p> </p>
<p>If doing loop siphons, I would make sure the drain connections allow air at the bottom of your loops. Like have the flexible tubing just stuck in uprights of say 1 1/2" or 2" pipe so that they will be able to suck air from both ends when the siphon should kick out. If you seal up a combined drain, there will be a tendency for all siphons to kick when one does.</p>
<p> </p>
<p>Now size of siphon needs to balance with flow rate and barrels cut the long ways can give some difficulty with siphons. I would probably do 1" plumbing through the grow bed and then adapt to whatever is appropriate for a loop siphon that will work with the flow rate (perhaps 3/4".)</p>
