<p>I had several of the 36 flood and drain beds I had running continually become clogged at the bell (or bulkhead for those that I had plumbed using a mega-siphon 2"stand-pipe, 4" flare and 6" bell housed externally in 1/2 of a 15 gal drum. Roots were the culprit and had to be constantly trimmed back as they would begin to grow into the piping. These beds had predominantly greens (mizuna, sorrel etc) that would grow for extended times and be cut weekly so the roots would really develop.</p>

<p>I have had a buried siphon for 3 years now and never needed to service it, I'm just not convinced yet that a need to service will happen frequently enough for it to be a concern for me. Others may worry about it more - but I like to live on the edge :)</p>

<p>Putting a double loop siphon in the grow bed is a good idea, I just see serviceability issues - have to remove the gravel to remove the standpipe. Even using 1" to 3/4" tee and 3/4" street elbows that doesn't fit within a 4" media guard, even barely in a 6-inch. </p>

<p>I developed what I call the EZ T Siphon - here is my video on it if you want a simple alternative to the bell</p>

<p>Adding an elbow to the outlet will likely decrease the time it takes to initiate the siphon, but it will slow down the discharge flow rate a small amount...however....when you add the media you will be reducing the volume that has to drain by ~60-70% depending on the media. You should target a total time of 15-20 minutes between gurgles...however...this is just a rule of thumb, the plants will let you know if something is not right. Reducing your flow rate or dropping the outlet pipe…</p>

Reducing your flow rate or dropping the outlet pipe elevation (if you can) will help break the siphon. A breather tube will also do the trick.</p>
<p>Also, you may want to consider going to 1/2"-->3/4" or 1/2"-->1" reducer on your standpipe, the size jump you are using is a bit much IMO.</p>
