Sprinkler pump pressure is small how should do?

When we use the sprinkler, there will often be a small sprinkler pump pressure, pump up the water situation. What should we do now?
First, check whether the sprinkler pipeline filter is blocked. Because the sprinkler pump pumped into the water may be not clean tap water, metaphor dirty pool or pond inside the water, these places in the water too much impurities, it is likely to lead to the filter is blocked by debris. Such as stones, discarded plastic bags, branches and other debris, only need to remove the filter screen in the tee, and then clean, to ensure that the pipeline is smooth, you can resume normal work, it needs to be explained that the filter screen in the middle of the sprinkler pump inlet pipe.

Two, check whether the sprinkler impeller is worn and deformed, which may also lead to the normal rotation of the sprinkler pump impeller but can not enter and exit the water normally. At this point, just replace the new impeller.

Three, check the sprinkler pump seal there is no gap, and lead to air into the pump pressure is insufficient. The solution to this problem is to carefully inspect the pump at work for leaks.

Four, check whether there is no water in the sprinkler pump pump, which leads to the phenomenon of dry dry water in the pump seal. If this is the case, replace the mechanical seal.

Five, check the sprinkler drive shaft power is insufficient, resulting in the pump impeller has not reached the normal working speed. Just step on the gas.
