I've got a question regarding the anti-siphon hole for my Marineland CornerFlo setup - 1 drain line, 1 return line. In the elbow piece there's a tiny hole that looks partially covered up that according to the Marineland doc is supposed to be the anti-siphon hole. I'm a bit concerned that the hole is pretty small and wondering if I should use a tiny drill bit and make it a little larger,; at least so it's round. Would this be a bad idea and am I worrying about nothing. Figured it'd be a heck of a lot easier to do it now before the tank is plumbed.
Here's an excerpt from the Marineland doc -
"Interior Return Plumbing
The return plumbing consists of a 1” bulkhead, 1” pipe, an elbow, and loc-line fittings that end with a Tee and two flared nozzles. The elbow has a small hole drilled into its inner corner.
The hole in the elbow is the Anti-siphon hole. Its purpose is to help ensure in the event of a power failure, that your drain plumbing will not begin to siphon and backflow a large amount of water from the nozzles into the sump. This hole is located in an optimal position to be less likely to become clogged by any passing debris. However, one common complaint is that it sprays water onto the Corner-FloTM panel and makes additional noise. We are currently looking at other options for accomplishing this safety feature, but, as it stands, this hole is required to help keep sumps from overflowing during a power failure. Modifying this hole will void the warranty of the Corner-FloTM tank."
