The original 1/4" pipe is undersized to keep up with the three 3/16" holes in the bowl. The drain needs to be drilled and tapped to 3/8" pipe which will keep up with the draining of the bowl (plus a 30% safety margin). If you have a turnkey machine, please check the drain size and if it's undersized please contact us for repair or follow these simple steps to drill and tap the drain. Items required to drill and tap the drain. 3/8-18 NTP tap. 37/64" drill or 9/16" (we used a 9/16 which is close enough and more common). Optional dead center to keep the tap straight. A drill press. Verify your drain is under sized. It will be about 1/2" across the threads. If the thread is the same size and the lid, it's under sized and will need to be re-tapped. Center the drill and get ready to drill. Drill the drain to a depth of about 1". You'll feel it break through to the other side. Use lubricant like kerosene or WD-40. Here you can see the drain re-drilled. This is the setup for the tap. You will use the drill press quill and dead center to keep the tap straight while tapping. Use the quill to provide stability while tapping. You only need enough down pressure to keep the dead center in the tap. The tap wrench is not shown. You can use a wrench with these larger taps. Use lubricate. Were using tapping fluid in this photo but kerosene or WD-40 will be suitable alternatives. Tap to about 3/4 of the tap length (depth shown). Lift the quill and remove the tap. This is the finished drain, enlarged to 3/8" pipe thread.     This photo shows the 1/4" pipe (left) beside the 3/8" pipe (right).
