    Hi Guys,

    I have just had a new tank built (build thread to follow shortly) with a slim-line overflow, which is bloody noisy??

    Is there anything I can do to reduce the noise on a slim line overflow?

    Please any ideas to reduce the noise would be appreciated.

    Cheers
    Michael B

    I've got no idea how those overflows work, but logic tells me you should have a ball valve on the line to the sump, if you close that slightly it should cause the water to back up in the overflow thereby reducing the noise, but you have to monitor it to make sure you don't close it too much as it may cause your display tank to overflow.

    viper357 is spot on. Add a ball valve and fine tune it so that you lift the water level in the overflow

    I also thought to have a slim overflow for a tank later this year but the ball valve has me worried. It sounds too much like something that is going to cause water spills. How are they constructed, surely one must be able to incorporate a safety overflow should the water level rise too much.

    Hence the reason when you design overflows you make sure you use big pipes and also use 2 pipes.

    Then only put a ball valve on the one pipe and adjust it.

    Works like a charm

    Thanks so much all - valve worked great (is a little scary though - balancing return & overflow)

    You can put a little level switch at the top of the overflow. So, if the water level rises too high, the level switch will stop the return pump.
