Manifold Design

[Koddie Doo]

Any thoughts on the sketch that I made for my manifold coming from my pump to the sump.

Hopefully my plumbing work is better then my drawing.:frog:

I would add a union directly onto your pump and give yourself an extra valve in your manifold.

+1, you may also want to add a check valve after the manifold T and below the union.

I would do an extra outlet next to the gfo and carbon for anything in the future you may want to add. Its a PITA to have to redo your manifold because you want to add something but dont have an outlet to do it with.

 

[Koddie Doo]

All good ideas, so at least I'm on the right track?

 

[kegogut]

Looks like it. I got my manifold from this place.

Cant remember where or when, but I was told when designing mine NOT to put the skimmer on a manifold.

pardon my ignorance, but i would just like to get some clarification since we are on the topic here.

what is the necessity of the valve on the return line?
are you trying to restrict the amount of flow through the return?

What was the reasoning behind not putting the skimmer on a manifold? Is it that flow to it can't be controlled by an AI unit to be turned off and on for cleaning and or feeding? Or is there some other reasoning?

 

[chucklez]

I could be completely wrong in this, but I think it had to do with keeping the same amount of flow going through it constantly.

I have gate valves on mine and I have to open them fully for a few seconds to constantly clear the gunk out. Basically, using a manifold when you have other devices added to it, or when adding devices you will need to constantly open or close the valve a bit to get the level you desire.

Make sense?

 

[Lance A. Lot]

Yeah... its not a set it and forget it scenario because of all the other variables from the other components attached to the manifold. I wouldn't want to be messing with it every time I change the media in a reactor.

You can possibly use it to restrict flow back into the tank, bit I think you would be better off putting those valves closer to where they actually dump back into the tank to control it better

. I think that valve is on the outflow side of the pump, heading into the tank. I have a valve on mine there as well. When I shut the pump off for maintenance or WC I close the valve to limit amount of water flowing back down into my sump from the return lines.

A valve on the return line and drain line just under the tank and above a union are necessities in my opinion. They can be used to control return flow and drain flow. I find putting them in there more important in being able to shut off both lines when something happens with your sump and you need to remove it. You can shut off the flow of water from the tank to the sump in both the return and drain. Second the placement of unions just below the shut offs make removing all the other plumbing easier.
