Because my system allows only ASCII code
excuse me for strange english expression

I read short zeit roman Sadoruninko of Seicho Matsumoto
Story is ungood men are sent to mine and pump water

When I worked at company
I made a equipment which pumps water from machine
The equipment was made from
electric float
two relays
switches
and pump
I think that someone can make water pump equipment from this novel
And I will implement pipe system call from this equipment
