    hi everyone
    i connected a ballvalve to my tank, but i find it really hard to get the correct flow. everytime i do something in the sump, i need do re-adjust the valve and it take ages to get it right. is this normal?

    A ballvalve is very time consuming to tune in to the correct flow rate. Also know that as the return pump gets dirty and the flow reduces, or when it is cleaned and it increases, the ballvalve will have to be adjusted. Its a pain in the backside and I had to learn to live with the overflow noise.

    are you using it to make it more silent or restrict flow?

    replace the ballvalve with a gatevalve.

    Gatevalve is expensive in relation to a ballvalve. but you can fine tune it a lot easier.

    i still dont see the need for a valve, unless its to slow the return down...
    what are you using for?

    Never use a ball valve to restrict the flow from return, you add back pressure on the pump putting strain on it.

    Only use a ball value to restrict back flow back into the sump during maintenance. But then also your back flow should be compensated for in case of a power outage and you don't over flow your sump.

    You should have you level in you sump to compensate for the water that back flows when the power is turned off.

    my return has a tee, one to the tank, the other back to the sump, not direct inline, else yes you will damage the pump.

    yip my sump takes 300L of overflow, as i direct siphon out my DT to sump, no overflow box in tank

    I think cizanie had the ballvalve on the overflow pipe going into the sump. People do this to try and get the overflow quiet. This is done by daming the water up in the overflow pipe. It workd great to reduce the noice but it does not work for very long as when the flow changes slightly it needs to be readjusted. The other issue is that if you only have one overflow and you restrict it too much then the display could overflow.

    I have not seen plastic gate valves that is a plain T-shape. All the gatevalves the shops have is the same one that we have on our skimmers where the water exits at 90 degrees compared to the inflow. And if you wanted to have the exit under water the turning knob would face down into the sump which is hard to get to. You can get around this by doing some additional plumbing though.

    Just put some sharp bends in your pipe, an angled entry into the pipe and it will be silent.
    That being said, when there is noise these is greater gas exchange and healthier waters.

    This is what the normal gate valve that most shops have looks like
