How can you pump out the water from a fishpond with a rubber tube?
Hold both ends of the rubber hose with both hands. One hand blocked nozzle, not to leak. Inhale with the mouth, suck the air out of the rubber tube, and then quickly put the blocked end into the tank. The lower end of the mouth is lowered and the water will flow out automatically. If there is no outflow, then put the rubber tube directly in the fish tank and inhale at the other end with the mouth. The water will be guided out, but the action should be quick, otherwise the water will remain in your mouth. In fact, this method is also from the oil tank in the car oil discharge method.
Can hand over water inlet, the water inlet end will be submerged, another person to the outlet to open the outlet end, both sides are ready to open both ends of pumping, the pumping process must remain in the water inlet end of the pond, otherwise have to repeat the process.
First, to make the water end elevation is equal to or less than the pond bottom elevation, with a rag like volume by water outlet end, not tight, no leakage on the line, one on the water inlet end station pool dike protection is slightly higher than that of embankment, the other one with the container to the rubber tube irrigation, until all the filling pipe, if small diameter
If there is no pump, siphon principle can only be used.
