Plumbing question

malac0da13 · 09/01/2009, 02:55 PM

Ok I have a plumbing question. My overflow on my 90 gallon has two 1.5 outlets. I was going to originally run one to my fuge and one to my sump but I thought about it and that would prolly be to much flow through the fuge. So my question is can I just put a "T" and ball valve to throttle the flow and just dump the excess into the sump? heres a diagram of what I was originally planning. Thanx in advance

What type of pump are you using? what's the GPH (after head loss)? A 1.5" drain line can handle up to 1200GPH. it won't be a problem as long as you don't have more than that (after head loss).

It is a Little Giant 3-mdqx-sc or some thing like that. I am not worried about that I was just wondering if that will be an acceptible way to have the flow be like 70% through sump and30% through the fuge.

i would just put both your drain line to one pipe then put a T fitting facing down then put a ball valve on it then run it to your sump so you can control the flow running to the sump with a valve so you can close it to slow down the flow or open it up more so you can have more flow.

I have two drains on my Tech 90. Currently, I have one drain to the sump and one to the fuge. I control the flow with valves on both pipes. The only problem is the Durso pipes are noisy. I am considering a switch to the "Herbie Method", using one pipe as a drain and one as the emergency back-up. I would "T" the drain, sending water to both sump and fuge, and limit the flow to the fuge with a valve. I ran a test of the method by running water at full siphon through the drain to the sump, and it was dead silent. You can find Herbie's thread on the "Lighting, Filtration, and Other Equipment" forum.

Your ammended plan will work fine. Would suggest putting a ball valve on both limbs (the one to the sump and the one to the refug) after the T: sometimes the resistance to flow down one of the limbs is surprisingly lower than the other. There is nothing more frustruating than wanting to increase the flow to one of the limbs despite the fact that the ball valve fully open but having no way to limit flow to the other (to shunt the flow where you want it). HTH.

Does this seem like it will work out good?
