I am guessing it would be smarter than trying to just get away with 1 3/4" back-up and using the second 3/4" for my return. Would it work to set up a Modified Bean Animal with a 1" full syphon and 2 3/4 inch back-ups? So, it looks like the bulkheads I have to work with are 2X 3/4"and 1X 1". The third hole is 1 and 13/16th (ish) The bulkhead that fits in there has an inside diameter of 1 and 5/16th THIS BULKHEAD FITS THE 1 INCH PVC Backgrounder: running dual 3/4 returns and 1 inch siphon, open channel and emergency drain (typical bean animal). Just making sure you understood that their price corresponds to the GPH capability/size. Hi guys, really need your help here as my drain keeps making loud splash noises, no matter how I tune the pump and gate valve. (maybe it's a 16th smaller than 1 inch now that I look close) so naturally I continued to think that they were 1 inch bulkheads. At modular marine the comparable 2400gph one is 187. Durso, Herbie, and BeanAnimal refer to the drain plumbing itself inside the overflow box. The bulkheads that fit in these two holes have an inside diameter of 1 inch. I have 5 holes in the overflow 3 of which are used for Bean Animal and they are 1. Having said that I actually had to do the same thing with the 210 Im setting up now. Under normal operation the main pipe runs like a siphon, in that there is no air inside it. If I recall Bean worked with the holes he had - which you pointed out. Have had an Herbie on my 210 since December and still silent. I just reset up a RR 75, and plumbing the Herbie part took maybe an hour including cutting the PVC and bonding them together. It now looks as if I have 2 X 3/4 inch ( both of which I thought were drilled to fit 1 inch bulkheads. The bean animal overflow is designed to be as silent as possible. In fact, pretty sure a Bean wont work on a reef ready without some ( ( perhaps major )) modifications to the overflow (s). It seems that what I have been thinking is a 1 inch bulkhead is actually a 3/4 inch bulkhead meaning it looks like it will only accommodate a 3/4 inch pipe. The emergency is positioned about 1/2 - 3/4' above the operating water level. It only occasionally drains water if the water level rises for some reason in my overflow box. The fittings themselves (elbows, couplers, etc.) are all a fraction larger to accommodate the insertion of 1" diam pipe. My secondary is positioned where the water level is about even with bend on the elbow. it seems that 1 inch (inside diameter) pipe does not fit into my "1 inch bulkhead", in the diagram the 90 elbow is marked 1 inch on the side that is saposed to fit into a 1 inch bulkhead and there is a 1 inch short piece of pipe that goes to the sanitary T after the 1 to 1.5 enlarger. Do you drill ALL THREE holes for the bulkheads at the SAME level I know the emergency. I get the overall design of the Bean Animal overflow but I have one question that for some reason I couldnt find the answer to. I really want to use the 'Bean Animal System' but Im just starting to research how to do it. Ive looked at a thousand pictures it seems and read quite a bit. This leads me to believe that I need a smaller diameter like 3/4 PVC pipe to join them. Im wanting to drill my tank back glass to install the overflows. The pipe at Lowes that was stamped 1 inch has 1 inch inside diameter but the outside diameter is larger then the bulkhead hole. If you cut a 2" long piece of 1" pipe, it'll slip into the 1" bulkhead nicely, and leave enough spare pipe on t'other end to attach your fitting, yet make the joint appear "seamless". The pipe itself (not the fittings) is 1". Nope, I get that there needs to pipe to join them. On a bean animal if both the main siphon and the first trickle get clogged the 3rd pipe would be there. I believe the thought process is if your main siphon gets clogged the trickle overflow would take over. According to the invoice only the bottom is tempered.Are you trying to direct connect fittings directly into the bulkhead? If so, that ain't gonna work. Ive used a Herbie for a couple of years now with no issues. The tank is built by Miracles and is 3/4" thick glass, with starfire on the front and sides.

Search titles only Posted by Member: Separate names with a comma. And maybe I can? That's where I need the help of more experienced people to tell me if this is feasible.Ī) Remove the current overflow and plug the holes. When I signed up for this design, I really wasn't aware of how much this would limit my aquascaping and flow options due to my inexperience. My tank is 96x24x30" tall which a large overflow to the left third of the tank which is 24" x 8" and takes up a massive amount of space. I'm currently doing a major revamp of my whole setup, and I want to address something that's always bothered me: my overflow.
