We moved into this house last year, The sump well was always filling with ground water & the pump going several times per hour.
The past month the 2 pipes have been dry & no water at all is draining into the pit, should I be concerned??
Usually, if there is a long dry spell, sump pump activity is likely to be less but it may take a few weeks before activity dies down.
This has to do with the water table, which rises and falls depending on the amount of rainfall.
However if there is an underground stream very close to your house, the sump pump may always be active.
If water collects against your house when it rains, you need to regrade the land or do other corrective action to eliminate that. It is not a good idea to add drainage pipes to channel ground water or gutter water into your sump pump well.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
