Plumbing help???

The Entire section from the Pump up is not ideal Solution...

From the pump You need to run a line Straight up with a few Bends and elbows as you can to the tank... Straight up then T off to each of your inlets inside the tank.. Putting a Gate / Ball valve above this T Creating a way to slow water going to tank and diverting to a Manifold. Explained below..



From somewhere in the straight up pipe.. Put a T PIPE.. Run it across Creating a manifold with several T pipe and then Gate/ Ball valves out of it dropping Downward toward your equipment...........

The way you have it drawn there are too many elbows and Complicates running the pipe...
I can draw a diagram if you wish.... Or just check out the Thread by BEND From yesterday...

The Drains look OK...

I WOULD ALSO MAKE it all with 1 1/2 inch or at least the Return to tank lines.. If your pump does not support 1 1/2 outlet just use a adapter... Leaned this the hard way..

Hope this helps.....

Im going to struggle running a manifold and dropping it down to the uv as I haven't got much height in the cabinet, I do see where your coming from with it all though and thank you for your input.

The biggest thing is to have the straightest shot from the pump to top of tank . then across to the bulk heads.
Then you can have a t off that main to go to a pipe with your valves..
Very close to what you have .except the t and 90s are not on the flow to the tank.[emoji3]

I see and iv had an idea from that which could work well. thanks.
 
No reason to upsize. The pump has the size discharge it has for a reason. You can spend the extra money if you like but the friction loss savings over the out let size will be less than 1 ft. Since you are already splitting the flow you will get a small reduction in losses there.

Looks like the DCT-8000 is 1.25 npt, that is the size you should use. That is a 2000 gph pump.


This is what i thought to be true as well. I even argued with people even a pump Manufacturer that knows there stuff.. I was having slower flow then expected and pump noise.They told me a 1 inch outlet on a pump needs to be plumbed with 1 1/4 min pipe but 1 1/2 Would be best...
They sent me a new impeller at my request But told me it would not solve my issue... They were correct... I ran all my returns to the tank with 1 1/2 and my flow increased by at least 30 percent and the Pump noise went away.
I Would have assumed more water in the pipes create more head pressure.But i was wrong... The Outlet pipe should be larger then the inlet . Sounds back word in my mind ..But the above has changed my mind on the subject.. But only because i seen it for my own eyes...

that 2000 gph is at 1 foot most of those pumps Drop off very rapidly at say 5 feet..... This is why i went with REEFLO Pump the magdrive pump was doing the job but with less flow

It is true. If one size up makes that much of a difference you are out at the end of the operating range and flows do drop off quickly there. When I worked at a pump manufacturing plant that was not a place we would run a pump.
Pressure is just he height of the water in a static colum. Diameter of th column does not matter.
 
Im producing a new sketch with 1"' pipe with less connections and using large bend sections instead of elbows for less flow restriction. I'm just struggling to make the manifold at the moment. It's looking like I may need another pump as I just don't have the height.
 
Another couple of thoughts - many people are making the argument that with all of the high flow, relatively low cost internal powerheads that can be had these days, having multiple return lines is really not that much of an advantage, if any. In the old days multiple returns helped with mixing water, but one Maxspect, Vortech, etc will move a lot more water around your tank than the return ever will. Greatly simplifies the plumbing. Unless you want dual returns for other reasons, might consider this. My own experiences suggest that the thought is right, the powerheads do a lot more than the return....
The discussion about return lines is interesting, I talked a bit with the support at Reeflo before getting my new pump, they also suggested that to really get the max out of a pump, especially if there are bends in the line, it will help to go to larger pipe. However, if the distances are relatively short (ie your sump is not in the basement) and any bends are gradual, it is not necessary to do this and reducing it somewhat is fine. Flexible PVC is your friend here....

btw, I love that Reeflo snapper/dart gold return pump I ended up getting, I'd recommend to anyone... My sump is in my basement, about 8 foot head with some twists and turns. With 1.5" pipe up into the tank stand, then 1" from there into the tank, I get over 2000gph when opened right up - not much loss from the specs of around 2400. I normally run it at about half that, with flow also going to my frag tank and fuge... I also have one of the new jecods you mentioned on my freshwater tank, they have improved a LOT this version, quite a nice pump.

Finally, if you are going to run any filter canisters, calcium reactor, or anything that might have changing resistance and therefore changing flow, think about getting a second pump to run it. Notion is, if you change resistance in the overall return line, you will change flow to the tank, and those Herbie/beananimal type overflows absolutely rely on constant flow to the tank... Its not an end of the world sort of thing probably, but it can make them much more finicky to control. Some people do it with no issue tho... Other things with constant flow - fuge, frag tank, carefully designed algae scrubber, etc, SHOULD be fine. Some people say nothing but the display tank on the main pump though, and that would be the safest way....

Thank you for all the great info.
 
so going off of the amazing information and ideas everyone has given me I have come up with I think my final idea.

Iv scrapped 2 returns and have one in the middle as I have 2 gyres for water movement as well as getting rid of the not so needed overflow pipe which gets rid of a lot of plumbing. Also I can feed my uv and reactor properly now as well as store my reactor in the sump encase it ever leaks.

What do you guys think?
