Good news....bad news....
As with all new builds there will be ups and downs. I was really excited to finally flip the switch on the entire system last night. Everything started flowing nicely, my concerns of the 26ft run from the tank to the sumps were overblown, my durson drains are dead silent, no leaks or drips from any of the plumbing that I did but when I went out to the fish room there was a stream of water coming from the return pump. I thought right away it was the shaft seal but quickly realized it was coming from the seal where the volute joins togethers. I tried tightening the screws but nothing is working. So after doing some reading and debating what to do, I have decided to sell the pump with full disclosure that it leaks at a very low price and replace it with a Dolphin 6250 pump. I have been extremely impressed with the performance and how quiet the 4750's on my closed loop are. New pump will be here tomorrow...thank you Amazon Prime!
