Placed in a technical duct or at the bottom of a closet, the collector distributes the water of the appliances of a room while remaining discreet but always accessible.
A necessity for PER (crosslinked polyethylene) water inflow.
In a room to be renovated (bathroom or kitchen), the water in PER feeds collectors (or nannies) which, in turn, distribute the water to the sanitary devices. This is called a hydro-wiring installation.
Equipped with an inlet and several outlets, the collectors make it possible to centralize the connections and the shut-off valves. Just install two to dispense hot and cold water.
From these collectors to sanitary fixtures, tubes run behind partitions, in building cavities or are embedded in the floor screed. Count the number of water points to feed and choose a collector that can accommodate at least one more. It will be used in case of transformation or renovation.
To distribute bathroom fixtures with a minimum of fittings, as part of a multi-ply tubing or PER plumbing renovation, the simplest is to install two manifolds (or nipples, see System D, n° 849): one for distributing hot water and another for cold water. Each, concealed ideally in a technical duct that must remain accessible, is equipped with an inlet and one to four outputs (always provide a collector with a further output if necessary). Manifolds equipped with valves make it possible to isolate each device, which is useful when it is necessary to repair or replace one.
PER plumbing: install a nanny (or collector)
- On the wall, locate the location of the supports, equipped with two collars to accommodate the two collectors (hot and cold water).
- Check the verticality of the marks, then drill and insert the dowels corresponding to the nature of the wall, here expanding anchors for hollow partitions.
- Secure the collars securely.
- The farthest from the wall (A) is placed at the top to facilitate the connection of the tubes on the different outlets.
- Fix the first collector at the bottom.
- Rubber bushings must be in place to prevent noise transmission.
- Garnish with teflon and plug the unused outlets and the end of the collector.
- They can be used if the installation is extended (renovation or transformation).
Connect the collector to the circuit in PER
- Fit a compression fitting on the water inlet.
- Connect and screw to the manifold by filling with Teflon (improves sealing).
- Equip the feedstocks with stopcocks.
- Install a seal. It is not essential to use Teflon.
- The supply pipes pass through the partition in the direction of the plumbing fixtures.
- It is best to sheath them to protect them.
- Fit a compression fitting at the end of the tube.
- Place the nut and then the ring.
- Flare the end of the tube and slide the nipple of the connection.
- Slide the compression fitting toward the end of the tube, then place a gasket in the female part for sealing.
- Screw the tube onto the manifold with a pliers.
- By crashing into the fitting, the seal ensures a perfect seal.
