SRC Member ervine Posted April 26, 2004 SRC Member Share Posted April 26, 2004 Hi guys... While my original setup would not flood during a blackout, after adding my external skimmer and chiller, it's almost 100% confirmed that a blackout will cause my sump to overflow.... As my sump is really tiny (1.5ftx1ftx1ft) it can't really hold a great deal of water... I was wondering if there's any good sources for check valves or something that can be easily adapted to hoses to prevent backflow from happening... Please advise... Thanks, Ervine Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted April 27, 2004 Author SRC Member Share Posted April 27, 2004 No one knows where to get check valve? Quote Link to comment Share on other sites More sharing options...
SRC Member typrobin Posted April 27, 2004 SRC Member Share Posted April 27, 2004 check valves are not 100% fool-proof....the water will still flow back into the sump,juz at a slower rate.... the best solution will be to get a bigger sump.

SRC Member ervine Posted April 28, 2004 Author SRC Member Share Posted April 28, 2004 Oh but AT's ones are huge... wonder if they have a smaller version Quote Link to comment Share on other sites More sharing options...
SRC Member nutx Posted April 28, 2004 SRC Member Share Posted April 28, 2004 Oh but AT's ones are huge... wonder if they have a smaller version hi, why dun you try to re-examine the ways to connect your equipment and water level. bec with check valve, the flow will be reduce, and upset your current water level setting.if may want to do a simple diagram of your connection, and water level for everyone to feedback.

Thanks, Ervine If you have a small hole at overflow & return pipe just on the surface of the water to break the siphon, I dont see why the sump will flood? Unless you are using more than 90% of your sump capacity. Eric Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted April 28, 2004 Author SRC Member Share Posted April 28, 2004 Sump is small.. that's the first point.. Second point is I have 3 routes that will flood my tank... 1st being the sump to tank output (which already has a hole) this alone will raise water level in my sump by about 1-2" 2nd being the chiller which likewise is set high enough to cut the siphon action but the reservoir in the chiller still dumps enough water into the sump to raise it by 1-2" 3rd being the skimmer which when empty will also raise water in sump by 1-2" I can afford only something like 3-4" before my sump floods... (sump was meant for my 1ft nano last time!!) I'm also apprehensive about the check valves.. it'll kill my flow tremendously siah... Quote Link to comment Share on other sites More sharing options...
SRC Member ervine Posted April 28, 2004 Author SRC Member Share Posted April 28, 2004 Okay here's a schemetic diagram of my water flow... it's relatively to scale... you can see how small my sump is and how little leeway there is for possible flooding... Please advise.. thanks! Quote Link to comment Share on other sites More sharing options...
SRC Member Guinness Posted April 28, 2004 SRC Member Share Posted April 28, 2004 Like previously mentioned, can drill hole at the top of the pipe (which can still screw up if a snail or some creepy gets stuck..... Or.... increase the height of your intake by 1" or so..... Without all the figures hard to calculate, but you will be suprised how much water 1" from a large tank of water is.

I already have the hole drilled.. but it's not enough... water from the skimmer and chiller chambers are enough to flood the tank... Quote Link to comment Share on other sites More sharing options...
