1. A water supply and drainage system for a multilevel structure comprising:
- a. a lower level plumbing system comprising;
(1) a first and second fixture;
(2) a first and second water supply line for supplying water to said first and second fixture respectively;
(3) a first and second waste line for draining waste water from said first and second fixture respectively;

(a) a waste line stoppage detector attached to said first waste line for detecting a backup therein; and
(b) an automatic shutoff valve in said first water supply line for shutting off water flow through said first water supply line in response to said stoppage detector detecting a backup in said first waste;
b. an upper level plumbing system comprising;
(1) a first and second fixture,(2) a first and second waste line for draining waste water from said first and second fixture respectively, and said first and second waste line connected to said lower level first and second waste line respectively; and
(3) a first and second water supply line for supplying water to said first and second fixture respectively, and said first and second water supply line connected to said lower level first and second water supply line respectively.

Abstract
A waste line stoppage detector and automatic water shutoff system is utilized to prevent the overflow of raw sewage from a plumbing fixture. Electronic shutoff valves are electronically connected to a waste line stoppage detector. One application involves using an electronic waste line stoppage detector. Another application involves using a diaphragm and switch waste line stoppage. A further application involves using a float ball and switch waste line stoppage detector.
