Solo77 Posted January 16, 2014 Share Posted January 16, 2014 Drill hole at the return pipe where u want to water level at yr main tank to be if everything stop. The reason being when yr return pump stopped for whatever reason, there will be back flow. As the water get sucked back to the sump, yr main tank water level will drop and once the water lvl dropped to the drilled hole lvl, air will gush in to stop the back flow. Hope this help and u may to surf u tube to see the explanation. 2 Quote Tank : 4 X 2 X 2 with low iron front panel and external overflow Skimmer : BK SM200 with waste collector Return Pumps : Red Dragon 6m3 and Ehiem 1262 FR : 2 X Deltec 509 & powered by AB2000 Nitrate Filter : Deltec NF 509 and tee off from AB2000 Calcium R'tor : Deltec PF 501 with RM secondary chamber Kalkwasser R'tor : Deltec KM500 Chiller : Pansonic 1 HP Compressor with 20m titanium Coil Wave Makers : 4 X Tunze 6055 with 7096 & Vortec MP40w Controller : GHL Profilux Lighting : ATI Powermodule 10 or 8 tubes Water Top-up : Water Top-Up tank powered by Tunze Osmolator External Monitor : American Pinpoint pH and Temp.

SRC Member riveria Posted January 17, 2014 Author SRC Member Share Posted January 17, 2014 Thank you for the advice, broz Awesome. I'll try it out. Quote Link to comment Share on other sites More sharing options...
JoeyBabooey Posted January 18, 2014 Share Posted January 18, 2014 yup! add my 2 cents.. definitely works when you drill a hole in the outflow. Quote Link to comment Share on other sites More sharing options...
AroDan Posted January 19, 2014 Share Posted January 19, 2014 Good and simple. But the problem I have is my outlet pipe opening is located just 1inch below the surface of the water. It's overflowed my sump once when I was overseas and came home to a flooded living room. Quote Link to comment Share on other sites More sharing options...

Anchorman Posted January 19, 2014 Share Posted January 19, 2014 Good and simple. But the problem I have is my outlet pipe opening is located just 1inch below the surface of the water. It's overflowed my sump once when I was overseas and came home to a flooded living room. IMO, Drill a hole half inch above your outlet pipe opening so when water level drop air will enter the pipe earlier to stop the back flow. Hope it helps.

AroDan Posted January 21, 2014 Share Posted January 21, 2014 Ok. I will take a photo and upload tonight. Now I so afraid of that happening again so I have to pass a set of keys to my neighbour just in case I'm overseas and it over flow. I check my tank using my home cam.

JoeyBabooey Posted January 21, 2014 Share Posted January 21, 2014 yea bro a picture would do great. also, like what bro Anchorman said, drill a hole above the water can already =) if need be, later i can post a picture here when i get home.

JoeyBabooey Posted January 21, 2014 Share Posted January 21, 2014 Hi bro, not sure if your outflow is similar to this but the hole is drilled at the bottom of the right angled section above the water of the outflow. Quote Link to comment Share on other sites More sharing options...

SRC Member sunny03 Posted January 24, 2014 SRC Member Share Posted January 24, 2014 I would prefer to drill slightly above the water line.... Maybe less then 5mm above water line... and the hole cannot be too ssmallat least 3mm or bigger If you drill below water line. . Before it break siphon your sump might already flooded..

SRC Member Boonboy Posted January 25, 2014 SRC Member Share Posted January 25, 2014 Saw some post where people just insert and air tube. Of course the other end must not be in the water. Maybe you can try(if you an air tube lying around). Quote http://boonboyreef.blogspot.sg Link to comment Share on other sites More sharing options...

AroDan Posted January 27, 2014 Share Posted January 27, 2014 Manage to drill 2 holes just below the water surface.
