Plumbing tips?

[bertz_maru]

i have a question.. what size is your return? and those black nozzle thingies at the end of the returns? also whats the GPH rate for a standard 1 inch drain?

Scott I am not seeing the need for the T's on the back of the bulkheads at the tank side. I know you have them so that it lets air into the line but they are not needed in your particular setup. What i originally meant by backpressure is if you have the straight pipe submerged in lets say 9 inches of water in the sump it will cause alot of backpressure if you are already close to your max on that line. I personally try to find what the max amount of water I will keep in the sump and then cut the pipe exactly at that mark. Yes you will have some splash right there but that can be resolved with either a lid on the sump or my 44 ounce plastic coke cup trick. Come to think of it your T's on the back of the tank can hinder your water flow, water pulls itself down the pipe and creates a suction, if you remove the suction you may lower the GPH of the pipe, try pulling them off.

Bertz,
The return pump is a Mag 12 plumbed with 3/4" pipe to a T then 1/2 to two loclines. From everything that I have found a 1" pipe should be able to flow 1000-1200gph, that will be decreased with bends.

Kevin,
I see what you are saying now. I took the bottom piece of pipe off the drains so that it drops in the sump, still the same problem. I tried capping off the T's and i get a loud noise from the water flowing into the drains but is looks like more flow. I have a few ideas to try (hopefully tomorrow).

Rich has his plumbed this way, may want to go take a look.

Two other options would be to have the drain lines submersed but with slits cut in them under the water line to decrease back pressure. You can also reduce the length of pipe that is underwater. This will also help if you plan on using a micron bag. You dont want to have to shut off you drain lines or submers the nasty bag under 9 inches of sump water to clear the bottom of the drain lines. Personally I'm thinking back pressure would be minimal.... if you pump is getting it in the tank then your drain lines will get it down to the sump....if they are not then you need more drain lines.

Why did you feel the need to resurrect a thread back from 2003 ?

[Amphiprion]

Because it's spam :p

[snoopdog]

I did not even read it, it was too early in the morning.

So, that's a good way to bring you around? Resurrect really old threads?

Worked didn't it ?
