Got the sump and much of the plumbing done today. The sump is not 100% finished yet but I am pushing ahead anyways. I will drain and add baffles and such at a later stage as I need this thing going and my other tank shutdown.
The sump:
This is the return plumbing all completed. Knife shutoff valve from the sump to the pump and a gate valve on the discharge side. It then splits using a Y junction into some 3/4 flex pipe and back to the tank.
Below is how the overflow is going to work. Its not completed as you can see. I ran out of pipe
To the right eventually will be an inline water change tank that will flow back to the sump.
To the left will eventually go to the left side of the sump where the fuge will be
Black arrow shows the normal over flow and blue the secondary overflow or emergency
When its all completed the Normal overflow route will actually be closed most of the time. Water will flow to the fuge and to the inline water changer (and back to the sump)
When I want to do a water change I would open the normal in this picture, shut off the water changer value and empty and refill the water change tank.
The pump is a reeflow barracuda and it is currently so noisy I decided to switch it off for the night. I installed it using some spacers and rubber washers (a lot of them). I thought that would be enough however tomorrow I will try a rubber pad. I just read I have to let it run for 48 hours non stop before I am allowed to complain about noise haha :/
