摘要
The house water supply device has an electrical pump (2) with a water inlet pipe (4) and a water delivery pipe (5) and has a pressure retention system for providing water in the water delivery pipe. A common, outward waterproof envelope is provided which partially encloses the house water supply device with the electrical pump so that water emerging through leakages is collected in the envelope.
