There is no difference between a Nepenthes and whatever other houseplant grows right next to it in the wild when it comes to which water they will be able to take. Nepenthes are not bog plants, they don't (naturally) grow in poor soils. That's my point: if your tap water's safe to drink, it's safe to water your house plants, including your Nepenthes, with. The idea that they can't take higher than 100, 150, 200, ... PPM is based on pure conjecture and hearsay, and completely disregards the actual growing conditions of these plants in nature.
Edit: just for your information, my tap water is about 330 PPM. No problems, as expected.
