Is it usual for a sump pit to never fill with water?

I hope this doesn't sound like a dumb question. I am in a new build and our sump pump has never once gone off, even in the heavy rain and the ground outside is clearly saturated. I've looked in the pit and it is completely dry always. Is this normal? I ask because we lived in a house previous to this and the sump was very active in that house. Should I get someone to come look at it?

I'm sure it's fine... you're probably just on a hill or something. They have to put them in for code these days I think, whether you need it or not.

Depends on the soil and your elevation vs water table.

You could be at the top of a cliff in the middle of a desert and code would require a sump pump :p

Be glad it isn't active (if all is well), it's less stuff to worry about (back up pump, battery backup, making sure it runs, dealing with the noise)

Thanks everyone. I am a worrywart. I just thought maybe they didn't install the weeping tile right or something. The one in our last house ran all winter,fall and spring, sometimes once every hour. It was only quiet a couple of months in the summer.

Your correct and I'm sure it is fine .
With a P.Eng Soils report perimeter drainage can be ommited because of "free draining soil ". And that is not a shortcut but a good thing . I owned a couple houses that were built on pit run / coarse gravel . I excavated then it rained for a week . Not a puddle of water . No need for a system that will never work . Look into the history of your home .

It's a brand new house, built last fall. My neighbour two houses down has a sump that runs quite constant, but she is deeper into the ground than me. The ground on the same side of the sump pit at my house is quite spongey and stays wet longer than the ground on the other sides of my house. I am just a little curious as to why that would be. In fact there are a few divots in the ground from the lawn tractor last year because it takes longer to dry up than the rest of the yard. I am just hoping there isn't a build up of hydrostatic pressure on the foundation that will come to haunt me in my house's later years
