WATER SUPPLY SYSTEMS 

Pipe-In-Pipe Systems using manifolds.
This system has been inspired from the parallel electricity distribution systems, as each tap is supplied with two pipes, one for hot and the other for cold water directly from manifolds. The hot and cold water manifolds are installed in a cabinet embedded into the wall

or directly fixed on the wall above the false ceiling.

The hot and cold water manifolds should be selected with number of outlets equal to the number of hot and cold water taps involved in each circuit respectively.
The PE-X pipes are installed inside corrugated sleeves with suitable diameter therefore in case of perforation or leakage of the pipe due to accidental causes, it is possible to replace the damaged pipe simply by pulling it out of the conduit and installing new pipe instead quickly without damaging the floors or walls. This simple replacement is not possible with traditional iron or copper pipe installations.
The location of the manifolds should be selected in a suitable central position in relation to the various taps connected, so as to guarantee equal pipe lengths as much as possible. Long Runs should be avoided in order to reduce pressure and heat losses.
Connecting the pipe to the manifold is carried out using suitable compression adapter with size suitable to the pipe dimensions. While the connections to the tap is performed using sanitary elbow connections installed inside the plastic box. It is necessary to cut the pipe precisely and perpendicularly to its axis by using a proper pipe cutter with sharp edges.
