Had a few people ask about my closed loop OM 4-way so I'll tack this here and hope it answers any Q or maybe generates more Qs
this is the 4-way attached to a Hammerhead pump. To all that have not done their plumbing yet put a ball valve between the pump and the 4-way
This is further up the right side I have 2 x 1inch holes high on the right side that are fed by one port of the 4-way
you can also see the plumbing that goes across the front of the tank high
This is the back of the tank. all 4 holes are fed by 1 4-way port
here is the intake of the CL and 2 of the right side jets. I have added Enductors to them
here is the left side. The entire left side of the tank is overflow. As you see I have 2 jets being fed by 1 port of the 4 way
And this is the front of the tank. You can see the 4 jets from above being fed by the last port of the 4-way
And this one is just for fun
Please feel free to comment and make suggestions. As we all know it's never done. It's always a work in progress
