Ninjabeaver Posted February 17, 2015 Share Posted February 17, 2015 So the other day I had bought the other plumbing parts I needed to make my 1.5" drain into a durso...but there isn't enough room in the overflow to fit the elbow onto the tee...Are there any other durso like modifications like not using the 90 elbow and still have a quiet drain?

TheClark Posted February 17, 2015 Share Posted February 17, 2015 You might be able to use a chop saw to shorten the T if you are close to getting it to fit. Don't hold it with your fingers though, put a piece of pipe in it to hold it, then cut the T off short. Then use a street 90 add a little teflon if necessary to make it tight. Hope you can pull it off! Quote Link to comment Share on other sites More sharing options...
Bombertech Posted February 17, 2015 Share Posted February 17, 2015 There is no reason to torture yourself. If you can make due with an extra 2 inches of overflow water draining into your sump on power down: I like to run a full siphon straight drain. You can set the siphon drain a couple inches below the surface of the water. For tuning, a gate valve works great, but, if you can tweak in small increments and have some sanity left, a ball valve can work. I set my water level to seep at the full open backup drain. It's completely silent. You can hear the RW-8's humming Quote Link to comment Share on other sites More sharing options...

Ninjabeaver Posted February 17, 2015 Author Share Posted February 17, 2015 (edited) This is what I do. Easy peesy.How close in height should the main and secondary be? My second is a 1" Thanks for the input guys. Edited February 17, 2015 by Ninjabeaver Quote Link to comment Share on other sites More sharing options...
TheClark Posted February 17, 2015 Share Posted February 17, 2015 I can see the full siphon as a straight drain for sure, how deep you need it depends on flow so it doesn't suck air. If you can, experiment before making anything permanent. For the durso, that definitely seems more challenging to keep it quiet without the T. Or alternatively, at least a 90 + street 90. On that config you can drill a hole in the top of the 90s and stuff an airline tubing just barely into it for the air intake. Good discussion!

Bombertech Posted February 17, 2015 Share Posted February 17, 2015 If you have a 1 and a 1.5, use the 1" for siphon. As for how far down you want the straight pipe siphon, usually 1/2-1" below the surface of the water to the top of the drain screen. The backup should only have a seep of water going down it. 6 months down the road, if you hear water going down the backup, clean the screen on the primary drain. As TheClark said, you can always dry fit everything and give it a run! Quote Link to comment Share on other sites More sharing options...

Bombertech Posted February 17, 2015 Share Posted February 17, 2015 How much flow is there? Quote Link to comment Share on other sites More sharing options...
Higher Thinking Posted February 17, 2015 Share Posted February 17, 2015 Herbie style overflow. That's what everyone is suggesting. Google that. Quote Link to comment Share on other sites More sharing options...
Ninjabeaver Posted February 17, 2015 Author Share Posted February 17, 2015 How much flow is there?I have a jebao 9000 DC for it. I need to level tank in garage and then I can do a test run Quote Link to comment Share on other sites More sharing options...

Ninjabeaver Posted February 17, 2015 Author Share Posted February 17, 2015 Also forgot to ask if stainless steel clamps will rust? Quote Link to comment Share on other sites More sharing options...
Arsonmfg Posted February 17, 2015 Share Posted February 17, 2015 Also forgot to ask if stainless steel clamps will rust? Definitely don't use stainless steel clamps, pick up some plastic snap clamps. http://www.hcl-clamping.com/Herbie-Clip-Plastic-Nylon-Hose-Clamp-Double-Grip-P1 I use a single gurgle buster on my tank and it's dead silent and takes little to no room. http://home.everestkc.net/jrobertson57268/HGB/HGB_construction.html Quote Link to comment Share on other sites More sharing options...
fishmanmike01 Posted February 18, 2015 Share Posted February 18, 2015 How close in height should the main and secondary be? My second is a 1" Thanks for the input guys. My main is near 4" below my weir, with my emergency at just about the top of my weir. Quote Link to comment Share on other sites More sharing options...
