I use a Litermeter and it pumps 40 feet across the house from the reservoir in the basement up to my ground floor tank. They are very exact. Best thing I ever did makes my life a lot easier. I am sure it works with other pumps too.

Sorry to ressurect this thread, however I am running in a similar situation here.
I've been doing my AWC with DOS and it sure helps the headache of logging 10 gallons of water from my shed in the house and then from the house to the drain... Now the part which I'm having troubles with... I've had RO tubing split twice on me at the dos nipples and I suppose this is due to t he fact that the tubing on the DOS is much larger than the RO tubing... so where can I purchase proper tubing for this device? I don't quite see how this device can cause a siphon and I also think it can pump at quite the distance although I haven't tested, my RO barrel and new saltwater barrel are behind the wall in the shed. |

Hi Ginu -
I just got some tubing from Home Depot. I am using it this evening, so I cannot verify that it is going to work, but it seems to be just the same as what came with the DoS. Most of the RO tubing I have ever used is much more rigid than the tubing I use for the DoS. Siphoning can happen. I saw it on my system just the other night. You are best off if you include a Normally Closed solenoid (about $12 on eBay) and have it turn on at the same time that the DoS starts pumping and turn off when done. Problem solved.

Problem I see with the tubing is that it will split if its not the correct diameter... as it has to be shoved on the nipple, then the screw is tight on the tube which will cause a split once the tube tightens up (what happened to me on two occasions now). The Neptune tube is slightly wider vs the standard RO lines, so even-though it might seem to fit, it will only stress the tubing in time which will cause a split. I do like the idea of a solenoid and might add this in my circuit as I just purchased a second EB8 which is empty at the moment. |

Just make sure that you plug the solenoid into outlets 4 or 8. The other outlets do not support such low amperage and may leave them accidentally turned on. EB4 will support with all 4 outlets.

Yup, I'm aware about that, thanks for the headsup almost forgot. Here is the tubing directly from Neptune. |

What I did to my system is take a left over piece of PVC tubing and drilled a hole on one side and entered the tube inside the PVC pipe, kinda halfway and that way it ensures two things, it wont get stuck to the side of the container and it acts as a weight keeping the tube close to the bottom and not ending up coiled up in the corner... The downside or upside (depends on how you look at it) of this method will always leave about 1/2" water in the container which I'm OK with as I don't want to siphon the bottom out anyhow (due to stuff collecting and salt debris at the bottom of the brute can). |

Been running 2-3 gallons changes each day with our DoS since March.
Love it

And honestly, its hard to beat this, not to mention I got it for roughly 200$: Best piece of equipment hands down. |

I wanted to follow up to see how this has been working. Can you provide an update please... thanks!

Mine just started over dosing the new salt water. Not sure exactly what is going on yet. I only noticed because my skimmer started freaking out cause the sump level got to high.

I really want to do this with the Apex DOS (dual head) but I'm afraid of a back syphon. Do you think that may have caused the over dosing?

No - first because it was technically a forward siphon, I think . Secondly, it stopped on its own each time. I will be running a calibration and let you know ASAP, though.
However, it is a good idea to use solenoids on any AWC system, IMO. Shawn

I'm not familiar with solenoids and how they work... more research coming. I appreciate you providing feedback on this! Thanks!

Pretty simply. For our hobby, it is an electronic valve that is typically a 1/4" input and output. For this application, you want one that is normally closed. Then, when you apply power to it, it opens and allows water (or supplements or whatever) to go through. You set the apex to have it turn on whenever the DoS is operational. That way it will be closed when not in use and avoid a siphon opportunity.
They run about $10 or so and come in a variety of voltages. I prefer 120v so I do not need to buy a power supply. They can only be used on the EB4 or the #4 and #8 outlets of the EB8. Shawn

Very good, thanks. I hate to keep asking questions but how do I wire to it? I see it has a male prong on it so I'm gathering I need a plug wire with a female end to connect to it. any idea where I can one of those at?

usually, I find that it is cheaper to just cut off the male end of an extension cord with whatever length of wire you need. Some come with wires and others with posts like in the link. For the posts, just get a couple of female spade crimp on connectors and you are good to go (home depot).

Okay I think I got it now. I was thinking I had to cut off the female end of the extension cord so I would be able to use the male end to plug into the EB8. Is that not correct?

Awesome! I read your post again and I see how I confused what you were saying. I truly appreciate the help and patience!

This biggest issue that will allow siphon is the number of rollers and the material of the rollers. The Dos Only runs two rollers, while this works, many of the higher end peristaltic run 3 to 6 rollers, with a two roller setup there is a chance that in a specific position it doesn't have the tube fully pinched. Its a rather small chance, and well I've never had my DOS loose siphon, as with AWC, you tend to do small frequent changes, so less time to loose siphon. Neptune probably recommends that the source be below the pump for the off chance that you haven't replaced your tubing before it bursts. Now Plastic rollers work, but they do not pinch the tubing any where near as tight as metal rollers and heavy duty poly housings. But then again there is a reason that these aren't used, as the heavy duty commercial and lab grabe pumps cost 4x more then these. |

Please go with this one http://www.ebay.com/itm/1-2-Gravity-...item45fb8709ee And get proper hose to tubing adapters. I have used almost every solenoid from this vendor, as I have aquariums, hydroponics and aquaponics... and each different model has a different use. Also the push to connect fittings on the 1/4 one are really awful, but one with proper threaded fittings, and then get proper thread to push connect for your tubing, or barbs, what ever you prefer. Even with a high pressure diaphragm pump on my top off system the "normal" valves need a few seconds to open as the supply side builds up pressure, where as the gravity fed rated ones open instantly. Another consideration when using solenoids and peristatltics is the use of a pre filter... sediment can really decrease the life of your pump tubing as well as sediment can also cause your solenoid to no longer seal tightly... both issues have caused me floods in the past and have been fixed by using 5 micron cartridge filters after my storage vessels. |

There is so much to learn... you can teach an old dog new tricks. Thanks for the help!
