My new manifold

[Creeper Reefer420]

I have been in the process of building out my tank.. I temporarily plumbed it with tubing so I could get the cycle started. I wanted to build out a manifold that was flexible, compact, expandable and easy to maintain. After weeks of research, I decided to go with a similar manifold that Pseudo built for his 120. Jackson had recommend the valves since he assisted him with the build. I was going to order it but decided to run to Lowes so I could get an idea of the parts I would need (since I never really worked with PVC). While I was there I came across PEX fitting which is basically heavy duty quick connect/sharkbait style fittings. After wiring up my RO/DI I figured it should easy plumbing with no glue, cement, primer. With the frigid weather, most of the work would have to be performed inside and with my newborn girl around I was cautious about the fumes/smell gluing PVC emits. After spending an hour at Lowes playing with the fitting I decided to give it a try. The great thing about is it can be reconfigured on the fly. This is what I came up with so far!:scratchch:scratchch

From left to right:

Return Pump - Refuge - Carbon - GFO - Tank

what will you have on the open end? if its close off i would recommend a small ball valve with an rodi line, to flush the air out of the system during maintenance and service times.. also the best way to maintain equal pressure to al ports is a loop type manifold bc with a strait line dead end type(mine is like this too) you get the best pressure in the first port and eack port you open you loose substancial pressure to the further ports down the line, if this makes sence

The opened end (left) will be connected to my return pump with a ball valve in between.

the return back to the tank? water will take the path of least resistance, strait through the large opening to the return, i would cap that off so you can regulate the pressure in the manifold to what is needed for the reactors, and Y off the intake to the manifold so your pump has 2 lines of pressure, one strait to the return and one to the manifold, also this way if you need to shut down the manifold you dont shut down all the water flow.. just an idea..

my system uses a manifold.. pump to a Tee, return to tank valved for flow rate, and one to the manifold also valved for total flow, and 4 outlets witha dead end, with a bleeder tube. i run my gfo, carbon, and nitrate reactors as well as my chiller heater system off the manifold, they all get returned to my sump through a filter sock just for added collection, my drain from my tank also goes through a filter sock .. im sure i got ahead of myseld like always, but i hope that helped you

I will be using a Eheim 1262 which will be plumped on the left side of the manifold using a ball valve to regulate pressure. The right side (hose barb fitting) will be connected to the tank return using 3/4" hose since my bulkhead is barbed.

I think the Eheim should give more than enough pressure to the manifold and return. However I do like the idea of using a Y so I could keep the system running while maintaining the manifold. Thanks for the suggestion!!!!

If you have a pic of your manifold that would be great! Thanks again!

i would put the ball valve on right, before it returns to tank. this way you can gate it back to keep pressure in the manifold. you already have valves to control reactors.

Edd, if I decided add a Y like what motor suggested, would it still be recommended to place the valve before it returns to tank? Before or after the Y?

 

[edd]

i don't think you need the y if you put ball valve on the right. but if you do use it i would put the ball valve after the y on return side.
what size tank is it going on, is the pump enough to feed reactors and tank?

I am going to set this up on a 60 cube. Right now I am using a 1262 which should be enough pressure for this configuration.
