    For a return pump, I do understand that I will need a big one. Was thinking an external, potentially a Waveline 10000. At about 12ft it will do 1600 g/h but offers the ability to adjust the flow from the pump. Likely looking to get between 1200-1400 g/h.

    As for the back siphoning. I would like a check valve, however I have read so many horror stories about them I'd like to not use one. If my calculations are correct, my return lines will be no deeper in the tank than 4 inches deep. If you calculate the volume of water you get 20 gallons. If my sump is operating at approx 25 or so gallons at normal operation, then it could easily accept that amount of water if the power goes out, eliminating the concern.

    At least that is my hope :)
    You may want to look at getting a much larger pump...1st off all manufacturers over rate thier pumps output. This pump is only rated at 2640gph @ a zero head, so it may only do 2200gph. Then it has a max shut off head of 16' at which point it won't pump any water....you're talking about a 12' vertical head going through a 17' return line ...the return pipe alone will add almost another 2' of head along with what ever fittings you have in the line, especially a check valve...they all add to dynamic head. I doubt that you'll get much more than a trickle out of the pump with this set up, let alone the 1200gph that you want.

    Also use sweeps or 45* anywhere that you can as 90* cut flow

    My thought was putting a 1" bulkhead with piping as close to the top of the sump as possible, then running flex pipe right into the existing drain line. That drain line then exits the house. Is that how you were thinking to do it?
    yup exactly, it's probably not necessary but I always think worst case.....what if....

    (I was also planning on a large auto-top off , was worried the valve would fail)

    Any recommendations on a pump that would accomplish this if the DC10000 won't? Looking for something efficient and external.

    I thought of a few more things last night but you seem to have considered them all, like piping an overflow on the sump to the drain. And taking the volume of the plumbing into account also.

    Sounds like you're on top of it. Can't wait to see some updates..

    I'm not familar with with reef pumps so can't help there, but what you need to do is add up the total dynamic head that the pump will have to handle...this will be the vertical height, return pipe lenght, number of fitting/valves etc and then look at the flow curves of the different pumps and find the one that gives you the flow that you want....remember that flows are over rated

    I was looking at the flow chart for the Waveline pump. The way I read it, I thought I would be okay.

    The flowcharts are made for a straight lift, I'm not sure how much each elbow affects it though to be honest. Looks like you'd be at about 5500 l/hr which is around 1450 gph. I'd say you're in the right ballpark for sure. As long as the pump isn't rated higher than the overflow you're fine.

    According to that flow chart you are at about 5500l/hr at 5 meter's (15') of vertical head. This works out to 1320.86 gph. This doesn't account for any loss in fittings or pipe. Like Graham says, every fitting has a calculated flow loss, this is higher in valves. When you take into consideration that these flow curves are determined in a lab somewhere, under specific conditions and the best results are translated into the documentation to sell pumps, your flow rate is going to be a lot less. This pump produces about 1500gph at 16' head http://www.reefs.org/library/pumps/p...in_as4700.html. This pump has a good flow curve and would fit your needs. http://www.reefs.org/library/pumps/p...e5-5mdqsc.html. Here's another http://www.reefs.org/library/pumps/p...2900seq21.html.

    I assume since these are at reefs.org they would be suitable for what you are doing.

    This Excel spreadsheet may help you calculate your exact requirements a little closer. It allows you to count fittings and pipe and head etc.

    I can vouch for the Sequance pumps as I and many others use them for our ponds and while they are slightly over rated on thier flows they still deliever lots of water and the are reliable.

    Well I was able to drill my two overflows and returns in the tank this weekend, and give it a coat of paint.

    Next step this weekend is drilling the return and sump lines in the living room floor.

    Fun fun...I have a sump in my basement... I have an Iwaki55RLT and it does a great job..1100 GPh i have 7 -8 vertical climb and a 6 horizontal run.

    We have some DC10k pumps at the shop if you want to come have a look...not running with that type of head pressure but I am pretty sure they will do the trick, one consideration is the DC pumps are having some issues we had one just cave on us and a power supply died as well on one.....

    On my new build I will be doing a ReefLow blowhole...nice inline adjustable pump that is efficient to run and proven to be a workhorse!


    let me or Cory (AFK) know if you need any info :)

    Did some research and those pumps do look nice. Small foot print, low wattage for the flow rates. I will certainly look into them further when I get to that point. Right now I'm starting to look at the baffles I need for my 50 gallon sump. Here is what I'm thinking:

    Click here to enlarge

    Looking at a Octopus skimmer that needs about 9" of water. Two returns, one split to give separate flow rate to the refugium. So each section will be 17.25" wide. I think that leaves me enough room in each section. Plan on using 1/4 polished edge glass, radius on each corner that touches the bottom of the tank. 1 inch gaps between the bubble traps. I'm thinking of trying to mount a piece of glass to the frame of the tank above the inlet section, drilling two bulk heads to mount my intake lines but don't know if the glass will stick to the abs tank with normal silicone.



    Anybody see any issues?

    for anybody wondering about cut glass for sumps, Dave and Admiral Auto Glass has reasonable prices and knows his stuff. They are cutting me my baffles, polishing the edges and putting dime radius on 4 of the corners that will sit on the bottom of the tank so that it joins with the existing tank silicone.

    All is good ....the return in the center is small you will be doing top off frequently...just fyi.

    Well now that summer is winding down and I have some more time and I'm back to work on this project.
    So sustain the additional weight I have braced the floor that will support the tank above.

    I have also mounted my Radions into my top by using some aluminum bars I modified, painted, and mounted with stainless steel screws. Routed the wires and installed an external USB connection outside the top on the far side which will be towards a wall to plug in my laptop incase I want to make adjustments. Wish I would have known they were going to come out with the Reef Link module to do it wirelessly.... oh well.

    I also completed a stand for the basement sump. Still has to be painted grey but holding off until I get my external pump and figure out where to mount it at the front of the tank. Also need to silicone the baffles I have in place and drill some holes. Currently waiting on an order from BRS with some plumbing items; bulkheads, gate valves, and some unions.

    So I will have two 3/4" returns, each one split with locline. I'm still up in the air on a pump, but I believe have narrowed it down to two.

    Waveline DC12000

    Reefflo Super Dart Gold.

    I want to also run a 2-3 outlet manifold I will build.
