1. Check the inside of the sprinkler pump: First see if the pump has abnormal conditions, such as water leakage, abnormal sound, stuck. If there is an abnormal sound, it should be the impeller is broken; If it leaks, the water seal should be damaged; If it’s stuck, it’s a broken bearing.
2. Cleaning the filter: If there is no anomaly, first check the filter, clean the filter, check whether there is foreign matter blocking the filter, if there is foreign matter, it can be excluded.
3. Check the valve switch: if the filter screen is clean, then check whether the position of the four-way three-way ball valve switch is correct, and whether the straight-through ball valve is closed, which is very critical, because there is often a driver friend who says that there is no pressure, the result is the wrong direction of the valve,30 seconds to solve the problem.
4. Check the inside of the tank: there is also a situation that affects the pressure, that is, whether there is something blocked in the water outlet of the tank, if blocked, it will cause insufficient water supply, and no matter how large the throttle is, there is no feeling of increased pressure.
5. Check whether the ball valve is normal: If the above problems do not appear, you should check whether the ball valve is normal. Some ball valves will be aging for a long time, and the surface looks like the wrench is rotating normally, but the inner core of the valve is not rotating, so the ball valve does not work.
6 Confirm the rotation direction of the sprinkler pump: before installing the sprinkler pump, be sure to distinguish whether it is a left-handed pump or a right-handed pump, if the installation is reversed, there will be no pressure or small pressure.
The above method is basically able to solve the problem of no pressure on the sprinkler.
Warm reminder: the sprinkler is still three points, seven points, the correct use and maintenance can maximize the life of the sprinkler and pump!
