I disagree. I would absolutely run an E drain. Not manditory but i would absolutly sleep better at night.
An emergency drain is a dry drain that takes on water on the event one or borh of the siphon drains become clogged. Its basically a herbie drain set up. Its almost damn near fool proof. Id spend the time doing it now before its up and running than doing it afterwards.
Again not manditory but why not add the additional safety.
If your interested i can explain more in detail. But woukd rather not type it all out if your cool with the current set up
Yeah I guess you could use the returns as the e drain and run your return over the back.
Oh man, I just put everything together. Can an emergency drain be run as an “over the back” overflow? The drains are not full siphon to my knowledge (again I am a sump n00b). I’ll post pics of the setup I did. The 1 drain on the left is a straight shot to the sump too... not sure if that matters.I would run the existing siphon drains as the edrains and the return as the siphon.
3/4 inch e drains wont be able to handle the flow of 1 inch siphons. Then again all of this is moot we need to know what gph ops pump will be pushing.
Would that raise risk of overflow failure? Maybe I'll remove them in that case. Thanks!I'm only guessing here but media in the overflow might become clogged since there is no mechanical filtration beforehand
