Basic plumbing tutorials? Looking for plumbing to a black water tank (for the future; composting toilet now) and a grey water drain (possibly hooking up a tank later, but for now, biodegradable soaps and drain to shrubs), plus a kitchen sink and a shower supplied with a hose from the house (with tankless water heater). Simple, simple, simple, please. So easy a 12-year-old's mother can help her do it.... :)
