Be aware that this solenoid does needs a slight bit of pressure to operate. I was intending for it to empty a bowl and it did not work because there was not enough head. For this you need a solenoid with a working pressure of 0 to 0.1 MPA and this one is 0.02 - 0.7 MPA . If you have an elevated tank it would probably work okay with a bit more pressure.
