    Hi guyz. I need some advice, i need to do my overflow on a tank i built. Its not a big tank so im thinking of using 25mm pvc. I want to drill the bottom, but i DONT want to build a box of any kind, not even a skinny one. So i was thinking of using a 110mm pvc pipe to act as a overflow box. With a modified durso in it. When i say modified i mean i'll have no 90' elbow coming out from the t piece. So water will enter the standpipe horizontally. Will it be silent? I will install a valve on the outlet to control the water level in the 110mm pvc pipe...

    Too small

    50mm will fit easily inside the 110mm. and get yourself a soil vent valve from Builders Warehouse. That is enough to be a durso. See the one close to me eventually got some in again.

    But a 110mm pipe in your tank is enormous. Cut a piece, and put it in. See for yourself before you drill the tank.

    Just remove the rubber washers inside. Drill 6mm hole on top, with airline valve. Jobs done, have a beer.
