Well there i was.

I have been looking at getting a reverse osmosis and de ionization system for a few months now, probably since around the same time I started displaying large amounts of water in my living room. However, like any Scott, I really didn't want to spend a dime on something to make already clear water, clearer. Of course, I had been doing a fair amount of research on the various 'brands', types, and configurations of these water wasting machines. Ultimately I came to the conclusion that they're all pretty much the same thing, water goes in and water comes out. The canisters and mounting brackets and tubing and fittings are all pretty standard (or are they). The differences lye within the quality of the filter media itself, you know, the sediment filters, carbon blocks, membranes, DI resin. So with my greatly, over exaggerated, fantastic, secret industry info in hand I began to search for all the hardware bits at the best cost i could find. I was planning on doing a sort of DIY RO/DI system, buying all the discreet parts, then assembling, and finally drinking, rather than pay someone else to screw some things together that I was fairly confident I could do myself for the cost of however many pennies my time is worth.

But then I came across a nice little commercial advertisement banner on Used Victoria for a water filtration system. I could hardly not take a look at the website, what with its Canadian Flag smeared all over the place, it had to be something good, right? Anyways, they had a nice system marketed towards aquarists called the Aquarium II System. A 7-stage Filter/RO/DI (1 sediment, 2 Carbon blocks, RO, and 3 DI canisters in series), the system came with all the filter media to make it a turnkey solution. I wasn't thrilled with the filters, after what my original research came up with, but thats fine as I was planning on buying the media separate in any case, all I was interested in was the hardware. And for the price they were asking, $149.99, 7 stages of all the hardware I needed sounded good to me. Then I saw it, their address, it was right here in my backyard (well Central Saanich). This is great, I don't even have to pay for shipping or duty, or brokerage fees.

I loaded up the car and went for the roadtrip out to Saanichton, where I drove up and down the street listed on the website looking for the address, expecting some sort of large commercial warehouse, and a big sign. Finally found the building or what looked to be an abandoned 2 level office building, and around the side was a door and a set of stairs. Long story slightly less long, got my system in a nice unmarked brown box, threw it in the car and drove back home.

Once back in the real world, all safe and sound, I began to put everything together as per the instructions on the website (well if you can call them instructions). Got it all together, plugged it in, turned it on, and... water began flooding out of nearly every orifice. The leaks seemed to be coming from the pre-assembled bits, the pipe thread sides of the quick connect fittings on the RO housing, ect. So I backed them off and examined the thread form and taper angle, and concluded that these fittings just aren't even pipe threads at all. Closer inspection yielded the Yuyao Shitong Purified Water Pipe Product Factory as the manufacturer of these parts, and some online research came up with little information aside from how to order a minimum quantity of 5000 units. Anyways, it seemed as though the fittings bottomed out long before any useful engagement of threads occurred, obviously due to the incorrect thread taper. So down to the nearest plumbing wholesaler to get some good quality fittings to replace the knock off junk.

All in all, my DIY project that evolved into a turnkey setup, de-evolved back into a full fledged DIY project. I suppose I can't complain too much though, I'm still well under the cost of any big name major water guzzling system out there, and the best part is I can still use the big name filter media in my setup.

For anyone embarking on an RO/DI system, whether DIY or turnkey, make sure the most important parts are not looked over, such as the smallest parts in the system. I would suggest going with something from Murlok, John Guest, or Watts when it comes to quick connect fittings; and stay away from the Yuyao Shitong Purified Water Pipe Product Factory, at least until such time as they can comply with ANSI/ASME B1.20.1

A clear view of the elephant http://tgvas.com/Forum/entry.php?2-A-clear-view-of-the-elephant Mon, 14 Feb 2011 04:53:40 GMT Well there I was. It was a normal Saturday morning, me standing in Blue World with a coffee in one hand and a Timbit in the other(or two or three......
Well there I was. It was a normal Saturday morning, me standing in Blue World with a coffee in one hand and a Timbit in the other(or two or three... Hey if I don't eat them Dan will!). The only difference this time, I was actually talking to people, yay for social development. Not quite sure how I got into it, but there I was explaining (or attempting to) how I designed/built my overflow. And all I got in return were perplexed looks, I knew that this was either due to me having a fantastic idea or more likely my inability to explain myself

Now I'm pretty new to all this, keeping water in glass houses in your living room type of thing, but I've had a 'rife smattering' of mechanical engineering experience of which I figure should be marginally useful to successfully entertaining Ichthyoids in my home. So I, as I'm sure every noob to the hobby, commenced in some good ol'e googling about overflows. In short, after a few hours, days, perhaps weeks, I was left unsatisfied with the options out there. You know the ones; Durso, Stockman, Herbie, Calfo, generic Overflow boxes. Don't get me wrong, all of these work just fine as they were designed, but each one has its pros and cons. Some are quieter than others some are.... well you get it, it's like Ford people and Chevy People right? Anyways, regardless of how well they work, they all have one thing in common - They look like crap. Really, has anyone been diving in the Pacific and found the overflow box? or perhaps snorkelling in Maldives and read somehting like "OEX ECOLOTUBE EGOUT BNQ 3624-130 X 0215 C P.V.C 60PSI@73 NSF-PW ASTM D1785 ASTM D2665..." down the side of a big white PVC pipe. You get the idea'r. Next to Powerheads, Overflows/Standpipes seem to be the Elephant in the Tank.

And that's where I come in :nottoosmart:

So I set to work designing something that would accommodate all of my requirements; the usual - Quiet, safe, and most importantly: INVISIBLE (or as invisible as possible).

My tank came predrilled from Hagen with a silly little proprietary bulkhead assembly, that included more parts than a swing set. In any case, I had two 3/4" standpipes to work with. After a few days at the drawing board and some calculations having to do with fluid dynamics, I came up with what I thought would work quite nicely. So down to IPP to get a length of clear acrylic tube (2 1/4" OD, 2" ID for anyone interested) with a stop at Corix on the way home for the appropriate size FPT and MPT ABS fittings. The PT fittings will allow me to remove my devilish device for cleaning, and also more importantly allow me to set the water level in the tank. After milling the slots in the top end (to allow water through of course), I attached the MPT fitting to the other end using some tank safe silicone. Following that, applied some silicon to the bottom of the FPT fitting and affixed it to the bottom of the tank around one of the Bulk Head fittings. Presto chango, a tank with a tube in it!

Following are some photographs for your perusal.
Personally I like the seeing the little bubbles at the top of the pipe more so than seeing a G.D. piece of Thermoplastic.

You'll notice that included on the menu this evening are:
-a full siphon, this takes care of the quiet part.
-an adjustable overflow (by the screwy bits at the bottom), this takes care of the safe part
-a cylindrical overflow tube, I'm not sure where it is because it's invisible.

Pay no attention to the little man behind the curtain (the black standpipe in the middle of the clear overflow. That's just one of the many parts to that silly bulkhead assembly. Next maintenance day, a Jr. hacksaw will take care of it.)
