Answer:

neither reliable nor valid

Explanation:

When a reading of a measurement is close to the actual measurement it means that the reading is valid.

When repeated measurements show readings that are close in value then the readings are considered reliable.

Here, the readings are neither showing the accurate measurement nor are showing the same readings repeatedly.

Hence, the pump is neither reliable nor valid.
