My parent's house built in 1967 had a wet spot when the foundation hole was
dug, this was 6 feet deep. The sump was installed close to that damp area
and developed a constant flow of water no matter how dry the summer. They
had a 40 foot deep bored well (3 feet in diameter, common in this area)
which started running out of water about 10 years after the house was built,
but the spring in the sump always flowed with fresh cold water.

You never know where there is water and what it will do.

The edges of some of my paver bricks are always damp, even though a
ceiling over them prevent rain from ever hitting them. The water meter
doesn't budge when all the faucets are off, so I suspect a leak in the
main waste pipe.

The house is on a slab, and located in central New Jersey, so the pipe
might be a couple of feet below the soil (and below the frost line).

Another winter problem is that the nearby blacktop driveway will raise
about two inches above the concrete garage floor following a couple of
weeks of below freezing temperatures. There had been a gap between the
blacktop and the garage that I just filled, so I don't yet know if that's
how the water was getting below the blacktop. Again, it may have been
leaks from the waste pipe.

Any tips for finding it?

Thanks,
