Basic Water Pump Q's

[IRoman]

Yes you need to increase the input to your sump another or bigger overflow is the only way to do that.

Thanks, Im glad to know I'm on the right thought process. Ill be making another overflow tomorrow and hopefully Ill finally be done with this plumbing mess tomorrow. I want the tank to start cycling already so I can get my fish!!

OK bro,
that clicking in the pump is definatly from air trapped in the impeller housing, so we know the pump is starving for H20...we need to be able to fill the sump at a greater rate...

From what I've been able to find out, a single 1" bulkhead can flow 600 gph...
a 1.5" bulkhead can flow 1400gph
if feed by one of those syphon overflows like I showed you before.
So I would say either a single 1.5" or 2 - 1" overflows will do the trick.

With the double 1", you'll have to find a way to get them both to dump into the sump, as well as get two syphons going at the same time...ehhh not so good...

a single 1.5" with the capability of getting you 1400 gph would be the better choice...

2" and you'll need a valve to restrict it down for sure.

I wanna see you get your tank up and doing fishless cycling too, lord knows you have put in the time and effort.
You are really close now.
If anybody has anymore flow info on sizes, please chime in...

- Fits with 1 1/2" bulk head fitting
- Runs and flows 1400gph from fish tank down to a wet/dry...

and the other one says

Fits with 1" bulk head fitting
Runs and flows 600gph from fish tank down to a wet/dry filter...

Er uh, ....dang it! The krylon fusion is drying on the second overflow right now. In the DIY Overflow thread, I read that anything bigger than 1" doesnt work. I didnt understand that but I just figured maybe the opening was too big confused: ) So I went ahead and made the second overflow.

I mirrored the second one so I will be able to put a T inbetween them, Since I have already built the second one, I am going to go ahead and try it. I am thinking about putting on valve on the bottom part of the 'T', that way if I ever need to turn it off, I can.

I will be putting up pics very soon of the new progress, hopefully this is the trick

Wow, this has got to be the best help thread I have ever read. I never got bored reading each post, every comment was as helpful as the last. Ironman, you were very lucky having all this help in the thread. I am saving this thread so that I can review it whenever I have issues with my sump. Thanks and congrats to all the help on this one.

 

[Dr Joe]

Do I understand that you want to connect the 2 siphons with a 'T'?

Hold off on anything fancy til you get flow right. No sense trying to troubleshoot 2 problems at once.

OK well that's alright...the "T" will be a bit restrictive unless you found one of those trick
1" x 1" x 1.5"...but hey, sometimes, you gotta "run what ya brung" right? Just "T" it as far down the line as possible, closest to the sump...

I bet that 39.00 syphon overflow is looking better and better all the time huh?...LOL

Excellent choice of paint btw I use it exclusively... my plumbing is nearly invisible against the black backround...

Oh yeah one more thing bro...anybody can go down and shell long dollars to have a pre-fabricated, cookie cutter setup...But a true DIY'r has all that and the satisfaction of knowing we have a 2-3K dollar rig at a small fraction of the price...best thing is, the MONSTERS could care less as long as their H20 is correct...

Doc,
he was still having some starvation issues with his overflow being light...he had the materials on hand so he is going to try dual 1" tee'd to increase the flow to the sump...
I suggested a 1.5" rated a 1400gph, and he'll likley go that when he sees how much hassle a dual overflow is to start the syphon etc etc...

I've never found this type of data so I'm going to do some real world flow tests on different size piping as soon as our 'hurricane' is gone and it quits raining a little. These will be simple 'over-the-side siphons', no anti-siphon gimmicks, overflow tubes etc. I'll post as soon as I'm done and cc to you.

WOO HOO!!



Two 1" overflows did the trick





They were a little hard to start, I'm honestly not sure how I managed to start them both. Originally I got one going and could never get the 2cnd started, when the pump opened up I was able too

Here is my return at work
