Nepenthes Northiana is reputed to grow on limestone cliffs. The
Nepenthes in and around Kinabalu Park grow on "ultrabasic soils".
The word "ultrabasic" does _not_ refer to the pH. Ultrabasic soils
are composed largely of rock sediment and therefore have a high
mineral content.
I agree with what another respondent wrote, essentially: watering
Nepenthes with hard water probably won't hurt them as long as the
water flushes the pot, so salts (and minerals) do not accumulate
to high levels. If you don't allow the water to flush through,
then salts and minerals will accumulate quickly as the added
water evaporates.
