    I have taken my side panel in for drilling a 32.5mm hole for the overflow, is this big enough or should i ask for a 50mm.

    Personally I would make it 50mm, I went through the same question a while back and I eventually went for the 50mm.

    The clever guys should confirm but, you can then get a bigger return pump and know that the over flow will handle the amount of water.
    hope it make sense

    Going for the 50mm hole will allow more flow from the DT to the sump than a 32.5mm hole. You can add a valve to regulate the flow to the sump. This will also allow you to make use of a bigger return pump as stated in the previous post.
    If you can, make the hole 50mm, you will not regret it.

    Firstly, what size tank do you have & what size return pump are you planning to use?

    I will go 50mm, And get the bulkhead fittings first. The hole is not 50mm, but slightly bigger.

    Going 50mm, and you should get all our plumbing supplies at any hardware shop. Going other sizes and you are limited in suppliers.

    But, before they drill, get the fittings!

    on a 500L tank I would advise a 32.5mm Hole, this would allow you to push more then enough return flow to the DT.

    Return flow is normally not a problem as it is under pressure. Making the return bigger will reduce the friction and there will be less losses in the head of the pump.

    To put this into perspective ...

    I run my return through a 32mm return on a 3500L system. Pushing 9000L/hr easily to and from my sump and Display tank.

    I however do not count on the return for flow in my DT.
