The cause of the water pump does not suck

Here there is experience with water pumps that require three times the new action result the water smoothly, following his review

1. first drilling, I entrust to the expert artisan wells, so install the new water pump I bought troubled, then checked by artisan wells, there is a sparpart that has the problem, then replaced and installed the result of water comes out but no water coming out so smoothly, until here contract with workers well is completed.

2. After several months of usage of the water does not come out, possibly because the sand is too much so and so clog jammed streets, water pump but water does not come out, after I report a provide information to other wells expert builders, the answer needs to be drilled shallow drilling again, okay I conformed to what the word workers well, the result of water comes out smoothly but there is still a little sand.

3. The lapse of a few days away, don't come out again, this time to my own decision to learn from the failure of the first and second are always problematic, I finally decided to buy a new water pump and good results thanks to its water discharge, sand out all and until now.

Of the three things above, I can deduce the cause of the water pump does not suck as a shallow drilling, then it could be because the water pump to the colour is less strong.
