The suction pipe from the well to the house should be installed at a/an _______ slope.

1. downward

2. upward

3. neutral

4. variable

The correct answer is: upward

The suction pipe from the well to the house should be installed at an upward slope. This is because gravity helps water flow through the pipe, so an upward slope will prevent any blockages or standing water. A downward slope would cause water to collect in the pipe, potentially leading to clogs and loss of pressure. A neutral slope may not effectively drain water and can also lead to clogs. A variable slope would also not allow for proper drainage and can cause water to pool in certain areas of the pipe. Overall, an upward slope is the most practical and effective option for the suction pipe installation.
