3 filtering water end (W.E.) mouth 4 can be connected to the filtered water stream road 7 of filter device 29, so as to get from filtered water stream road 7
Drainage.
In the present embodiment, detection channels 1 are located at the outside of raw water runner 6 and filtered water stream road 7.Detection channels 1
Entrance (i.e. one of openings 8 of detection channels 1) can be connected to and filter water end (W.E.) mouth 4 with the raw water port 5 of switching mechanism 3 respectively
Connection, to accept the raw water separately flowed into from raw water port 5 and filtering water end (W.E.) mouth 4 respectively and cross drainage.
Switching mechanism 3 includes shell, is arranged in the intracorporal piston 21 of shell, a side end face (one of stress of piston 21
Portion 22) it is corresponding with raw water port 5, another side end face (another one forced section 22) is corresponding with filtering water end (W.E.) mouth 4.Work as work
When pressure suffered by one side end face of plug 21 is greater than pressure suffered by pressure face suffered by the other side of piston 21, piston
21 under pressure to direction (i.e. towards the direction of filtering water end (W.E.) mouth 4) movement far from raw water port 5, so that raw water
Port 5 is connected to detection channels 1, and detection channels 1 and filtering water end (W.E.) mouth 4 disconnect.In this state, can have in detection channels 1
There is raw water, detection unit 2 can detect raw water.The pressure suffered by another side end face of piston 21 is greater than piston 21
A side end face suffered by pressure when, piston 21 under pressure to far from filtering water end (W.E.) mouth 4 direction (i.e. towards raw water
