    I built the same one. Is filter housing filling with water? Sounds like it may not be plumbed right. Can you post a pic of it? plumbing is simple but one connection out of place and it will throw everything off

    thanks for the reply, I will post a photo tomorrow, I think my membranes are not seated properly. From what I have seen on u tube it seems that the plastic nipple on the top of the membrane should be flush with the top of the bottom housing, mine are not and I cannot push them in any further. I believe that are applied membranes.

    It turns out that they sent me housings that were not compatible with the 150gpd membranes.

    Sorry to hear you are having problems but glad you figured it out. I wish there was a local place to pick up the materials instead of having to order all online because sometimes you get the wrong things sent.

    sorry have not been on the site in a while. Running it on gas I am not too sure about how to do - only thing I can think of is hooking it up to a generator or a deep cycle battery - like ones used for electric trolling motors?

    Built a system last year from Brets diagram and parts list, and we are very impressed! Cut our boil times way down, actually got some sleep lol!! Not changing a thing for this year except will probably have a new set of membranes on hand just in case the originals go belly up halfway thru season. We dont have power at our shack other than a generator which I hate to hear run, so we are using deep-cycle !2 volt batteries, running an inverter to take it to 110 VAC, then a transformer takes it back down to 24VAC. We have solar panels to charge the batteries back up. Works pretty slick. Thanks again Bret for all the info. Ready for winter now!!!

    Way back when I started this thread, I spoke to an engineer at Aquatec and he told me you can actually run the Aquatec 8800 on 24VDC. It doesn't need to be AC because it has internal rectification anyway. So next season, you can just connect two 12V batteries in series. It doesn't get any simpler than that!

The aquatech pump runs the 4 that I have in series keeping 120psi throughout so it may be possible. I am interested in seeing what others may think? Please post if you give it a whirl. I just set everything up and it looks like we will be in full swing here in CT later in the week with temps approaching 50.
    For next season I am going to try this with the 400GPD membranes and see how it goes. I'm wondering about the setup though. You have them in series and I'm wondering about setting them up in parallel. Being new to the whole process I'm trying to understand this a little more. With one membrane 400GPD should yield about 16GPH, correct? I know that is somewhat reduced with the temperature of the sap. If the membranes are in parallel, does that mean that would increase the output to 32GPH?

    Another thing that I'm wondering about is the pressure. The Aquatec pump is capable of 150PSI but if the output is going to two membranes, would pressure be effectively lowered to 75PSI?
