BULKHEADS?

  • We are currently upgrading MFK. thanks! -neo
sorry i thought that i would offer some advice because if the rubbermaids are all on the same level and on the same level as the sump you wouldnt have to worry about losing siphon or flooding the only way you would lose siphon would be if the water got to low i was just trying to help and by the way a simple pvc overflow is CHEAP to make i made mine for $4
 
I had to make one after hours of fish stores and did a Home Depot run.
I do not remember what it cost, but it is made from: (top to bottom)

female couple (inside overflow)
gasket,
male to solvent,
overflow wall,
another gasket,
washer,
female threaded reducer,
barb with male conector,
hose.

Of course, can be altered for your needs.

Home Depot has 2" shower drain flange fittings with gasket and clamp down nut. These will work in almost all aquarium filter overflow applications; however be sure to test any pipe fittings you will be using on either end of the fitting. A good supply house for bulkhead fittings and lots of aquarium supplies you might not find elsewhere is http://www.jehmco.com I purchase a lot of fish room equipment from them.
 
Did you already buy tubs? the reason I ask is I am doing a simalar type of set-up. I actually got sick of the the bulkhead search and got the Rubbermaid tubs with the drains at the bottom. I will run a tube up from the bottom of the tub (from the drain) to just under the waters surface, and as you said let, gravity do the work. I am going to put check valves after each drain so I can adjust the flow to work with my pump (pumps water back to the top tub), which is in the last tub (the sump, lowest one). With air stones in each tank, I figured that if there is a power outage, I should be alright. The tubs will not drain out, becuase the intake/overflow tube is just under the waters surface, which will only allow so much water to drain befor the flow is lost. I would like to see how you do your set-up miles, maybe we can exchange some ideas. Anyways good luck with your project.
 
Where can I find some rubbermaids with Drains in the bottom?

I'm not talking big ones.. I'm talking the $0.99 kind from Wal-Mart. Say, 4 or 5 dozen of them.. all on one system.

I will have to go look into the shower fitting.. But I think I figured out how to make one out of PVC fitting and some washers..
 
Greetings all.

This discussion certainly caught my interest. I'm in the process of setting up a 200g with two overflows in the back corners, drain and return holes drilled in the bottom. I'd like to hear how folks have connected their bulkheads to their wet/dry and returns. My bulkheads are of course threaded on the exterior but not the inside. My wet/dry came with flexible hoses (sort of look like a vacuum hose with 2-3" plastic collars at each end). In addition, I'll have to fashion some way for the returns to climb inside the overflows to bulkheads near the top. Rigid pvc with an elbow? Can you buy jets that allow you to change the direction of the flow back into the tank?

Any help much appreciated.
 
a bulkhead CAN be made into a simple overflow

there safer than overflow boxes

if theres a power outage and the siphon breaks and the power comes back

YOUR SCREWED!!!

My over flow box does not break its siphon if the power goes out. The intake pipe that goes to the sump on the back box is higher than the U tubes that transfers the water. This prevents the siphon break in the event of a power outage. I have had a problem with the water cascading into the in-tank box causing alot of bubbles that collect in the U tubes and slows the flow of water, this could also cause siphon break if not noticed. To solve this problem I use two U tubes This increases the flow so fast that the bubbles are washed through the U tubes by the water.

Oh, I see. Yeah, I was talking about the big ones.
