Without baffles your sump can and should be completely silent. We don't use that kind of thing in freshwater so there is no reason to put in baffles. You will frequently see baffles in sump designs because most sumps are built for saltwater and saltwater sumps usually have a place for a protein skimmer (which usually needs water at a specific and constant height), a refugium, or both. There is no reason to have baffles in a freshwater sump. I would put the dry emergency anywhere it fit naturally and above the waterline so if it activates you will hear the water coming into the sump and know something is wrong.Īs your sump is currently designed, it will be making so much noise with the water going over those baffles and crashing down on the other side you might not notice if your emergency ever did activate. I would use 2 to 4 (depending on your level of ocd) foam walls to seperate where the water comes into the sump from the rest of the sump. I would direct your siphon and your durso under the water level without bothering to split the flows. Anyway, long story short, remove the valves on the durso and emergency. There is absolutely no reason to EVER put a valve on the dry emergency and a few reasons not to, most notably, that you might accidentally close it and not realize it till a disaster happens. But otherwise there is no reason to put one there. Some people put a valve on the durso purely so they can test if the emergency drain is capable of handling the water flow in the extreme situation where both the siphon and the durso are completely clogged. There is very little reason to have a valve on the durso and getting rid of the valve will save you a little money and little simplification. There is an important distinction because the durso basically will always have water running through it (though in a bean animal it is very small amount), and as such it should not be treated the same as an emergency drain. I think you are calling the durso the 'first emergency'? Thanks.Ī bean animal is made up of 1 full siphon, 1 durso, and 1 dry emergency. I think I may be favoring this plumbing layout.Īny comments, insight, or tales from experience are greatly appreciated. Will this cause more noise than Design #1, or is it negligible?ĭesign #3 is similar to #1, but with first emergency durso drain (the one that may move some water) is tied directly to the main line primary full siphon piping. However, my concern here is the two 45* elbows. I like how this design looks under the main tank, despite the gate valve no longer being concealed. The main primary full siphon piping on the other hand has the gate valve just below the overflow, and then after the 60* elbow, the piping runs through two 45* elbows before hitting the double 90*. My only concern is the cross of the one emergency pipe over the main pipe (under the main tank) is messy and may be a pain if I were to have to repair something in the future.ĭesign #2 has the two emergencies durso and dry emergency drains coming down and over to their respective sump entry points without crossing over any other piping. As for the emergencies durso and dry emergency, there should be little to no water flowing through the first emergency durso drain, and nothing flowing through the second dry emergency if they were moving water, they would make a lot of noise, which would be the "alarm" that something is wrong. My logic for the main primary full siphon piping is to have the water flow as smooth as possible down to the sump and reduce noise. The two emergency durso and dry emergency drains both come down to 90* elbows, and through another 90* elbow down into the tank. I'm in between (3) layouts for the drain plumbing and I was looking for some feedback, please.ĭesign #1 has the main primary full siphon drain coming down from the overflow, turning 60* and through a gate valve (Spears' tech support says that the valve stem CAN be configured downward in this manner), down to a double 90* elbow, and finally to two 90* long sweep elbows and down into filter socks. Hello, I'm in the process of sketching out (or over engineering? lol) a 40G sump layout for a 125G tank with a Bean Animal overflow system.
