Plumbing help

[biggredd]

So I'm putting my plumbing together and seems to be a hassle to say the least. I have provided a picture from my cell phone of my tank in the process of being set up. I built this stand. It took forever but I'm confident it will last forever and looks nice. Doors still need to be painted.
My question about the plumbing is...is it ok to use 90 degree turns through out the plumbing? My sump is directly under the tank so I need the plumbing to go down from my tank turn in under the tank and then turn down to go into the sump. I've already spent about $70 on plumbing and feel I'm not close to done spending money on it. I just realized if I need to take the sump out I don't have unions to disconnect anything. I feel I'm running out of room to keep adding pieces even though the stand is big.
My plan is two one inch pipes coming down from the overflow. One pipe at the T will go to the fuge and I will put a valve on it to adjust the flow. The other side of the T will meet with the other tube from the overflow and combine into a 1.5" pipe to the sump. I have a valve on that too (Which cost $11 just for that valve - crazy). For the return the pump has a one inch outlet but was told to go 1.25 up and then split to one inch pipes to either side of the tank. I have a diagram attached to clarify how I think it should go.
But now I have another question. How does everything get held in place? The piping shouldn't be freestanding or it could just get bumped around and knocked loose. I have some ideas and have been looking around on here but don't see any good pics of how people keep everything in place.
I so want to add water but this is stopping me. I've been working on this for three months and is just another roadblock. (The stand took forever since I'm super busy all the time with school, band, work, girlfriend, snowboarding, etc, etc, etc, etc, lol)
Sorry for the long post but I appreciate all the help I get on here.

alot of other people will chime in but ill answer the easy questions.
1.your diagram looks fine
2. you need pvc pipe glue to hold everythign together, wherever you buy plumbing they have the glue, but work quick with it cause it dries FAST and oonce it dries your NEVER getting it apart
3. you can use as many 90's or 45' coukpings etc. as you want but just be sure to calculate head pressure loss and loss with your plumbing(90's, couplings, t's etc.) so you make sure you have the right pump and its strong enough
since we cannot post links email me at psusocr@aol.com so i can telly ou where tog o to figure out your loss with your plumbing or simply give me all the facts on your lplumbing and ic an figure it out for you!!

Just a quick 2c 45's work much better flow wise(don't lose as much) than 90's

Don't trust me huh redd. Thats OK no worries. Always good to get a second opinion....
What do you think PSU? You happy? Got flow?
2 45's will give you the same amount of loss then a 90. Get some plastic hose clamps and place them under the stand for support. Use a FPT/slip elbow on your drops and MPT/slip coupler for the down pipes to the fuge and sump, this will make them able to come apart. Not as quick as a union but will still work.
On the returns, put a t and then 1" 45's pointed toward the corners of the tank. Use spaflex to the 90 U shape that will hook over the tank. If you want to hard plumb then what you have will work.

BTW I did post on the other thread yesterday if you didn't see it.....

What about keeping it in place? How does it stay solid so I can wiggle it without it moving.
I have cement and all that good stuff ready to go. What exactly should I use to be able to take the sump out without having to break the pvc cement, a union?
But again, the important thing here is how I attach it and if multiple turns are OK.
My pump is a RIO 32HF rated at 1,900 gph (but I know won't go that much and have a valve on it).

if you dont want to mess with pvc pipe you can use the flex hose, most LFS have them,
The *****'s and petsmart's will definately have them.
Its really your choice, I have a 210 w/ a 2400 gph pump, I have 90's on mine and have no issues, just make sure your pump is big enough, figure 10x your tank.
On my 55 I had a 600 gph pump that worked out nice.
if you decide to use pvc I would definately put some type of disconnect in!

hey red,
HONESTLY , if anyone gives you advice that you should take it from its TurningTim, beleive me he can get you not only setup but setup the right way with maximum amount of flow.
Tim basically plumbed my 300 gallon system which consists of a 300 RR main tank a 45 gallon sump and a 55 gallon fuge! he really is great at what he does !!
and BTW ditch the RIO their JUNK , if you where using it as a powerhead i woudl say go for it, but as a main pump this could be a disaster! iw ould never trust a rio for a main pump!

Thanks PSU, But I must give credit where credit is due. squidd is the master, I'm just a wee-little grasshopper that knows how to do math.......
