Setting up a new tank for the first time in about 9 years and I'm struggling to understand ho to make a silent overflow with my new setup .....
as you can see from the pics there is an internal overflow screen plumbed to a bulkhead on the back of the tank which drains into the sump. the company that built this for me also included an external overflow box attached to the bulkhead. unfortunately the box was too long to fit in the space between the return bulkheads.
So I just installed a gate valve in line from the overflow drain bulkhead to control flow if needed. when I filled up the tank and turned everything on to do some leak checking because the water level does not completely cover the overflow drain you get this continual sucking noise.
Can anyone tell me the best way to solve this? Currently the 2 return pumps are on their lowest flow setting.
