<p>It is a well known and a very serious problem that pipe installations in the floors of buildings may give rise to serious building damages whenever leakages occur. With the invention this problem is solved by arranging all the pipes (30) in surrounding mantle pipes (12), which are laid out as a real, sealed waste pipe system, the mantle pipes (12) extending all the way between the floor surface at pipe uplead places (14) and the interior of a collector drainage box (22) connected with the sewer system. Leak water from any of the pipes (30) will then be drained off without any possibility of getting in touch with the building, and in the drainage box may be placed a moisture detector for producing an alarm signal. Besides, the use of upleads of the mantle pipes (14) all the way up to the floor surface involves the further advantage that the floor may be finished by the laying or casting thereof, without later mending at the uplead places.</p> |
