150 Gallon Build Thread ... From the Start

Outstanding looking! Good job.
 
Thanks a bunch. It sounds like mine is the exact leak you found. I havent' been able to trace it to the connection - it seems to be come more from where the tubing attaches. But, I will certainly give your suggestions a try. What I read / found / saw said to point the valve tips in the direction of the water flow. You point yours in the opposite direction - correct? If it cuts down on the pressure on the O-ring it only makes sense.

I will take it apart tomorrow and lubricate the O-ring. See if I can get it to stop the small leak.

Thanks again racr for the help.

Coy,

The direction of water flow should come from the male side of the connector. The reason for this is that the actual pressure on the sealing o-ring will be less. In this orientation, the only pressure on the o-ring is backflow. If reversed, then the pressure on the o-ring is direct. The nature of fluid dynamics is that the pressures are not THAT much different, but may be enough to solve your problem as it did mine.

Open up the connector and observe the valve tips. If you point them toward the source of water (opposite direction to flow), then the water will run through the male side of the connector into the female side.

I'll be happy to take a few pictures if you'd like.

Good luck.

Since I am just a bit slow on the uptake, a pic or two would be great! Thanks for the offer racr!

All these valves (we have 8 total on 2 tanks) are setup the same (backwards?). I guess they should all be changed around, or just the one with the leak? BTW - it's not "really" easy to find a replacement. I looked for a bit on the Internet last night.

Here's a picture of the double tap on the intake (the larger 16mm hose). The water comes down from the top and you can see the male end with the o-ring. Thus, the water flows through the male side to the female side. For the return line (the 12mm hose), the connector is oriented the opposite direction. My problem was with the smaller return line.

Anyway, I hope this helps. let me know.

Great tank! I'm a few months ahead of you with my 150g discus tank, but I went with fake plants and my stand is no comparison to yours. It's been a great read so far.

/\ /\ Thanks racr for the pic. Water flowing away from the O ring only makes sense. I pulled a forum post that said to install the connector the opposite direction. It sure would be nice if Eheim could throw a photo or a couple of lines of instructional text (in English) in their box. Would certainly make the install much easier. Thanks again for posting the pic.

The crazy thing is that after a few days (the replacement connector has been ordered), the leak "seems" to have sealed itself. I'll continue to watch it and see what happens.
 
yes yes a mother of a thread...... i agree with the lenght over height as my 48x24x24 is too deep for expert cleaning and pruneing. As filtration goes i have owened sunsun 1400 a eheim 2250 and a fluval 305 and i would say overall that fluval are the best filters on the market. They have amazing build quaulity and the back up if anything was ever to go wrong, FX5 and maybe a 305 as back up at the other end.

Altogther though if i could start again i would have definently puut in a sump filter for my two tanks, say a 55g could handle the load and energy consumption would be minamal as heating is done in there and only one pump to push it back to the top. Cleaning yr sump filter is alot easier than digging out my canisters also.

on planting I over plant with amazon sword to give my young sevs fresh green food, you could do the same for any young discus{amazing fish} you are planning on owning. OOOOHHH no im planning a bigger tank already in my head, look what you've done aaarrrggghhhh.
