Do all ultrasonic tanks have a drain valve and tap?
Emptying an ultrasonic tank

All our own brand "Best Ultrasonic" ultrasonic tanks from 6 litre and larger have a drain valve and tap fitted. They also have a length of hose.
2 Ltr & 3 Ltr tanks do not have a drain function. This size of tank is small and easily poured down a sink.
The thread size on DK Sonic & GT Sonic ultrasonic tanks is: 1/2" BSP (half inch BSP).
A 3 Ltr tank isn't much heavier than a kettle when it is full and so is easy to pick up and pour into a sink for disposal of the fluid.
