Sanitary manifolds are an increasingly popular alternative to branch distribution of domestic water. The main advantage of this solution is the elimination of the risk associated with making tee pipe connections in hard-to-reach places, e.g. in floors or walls, the repair of which in the event of leakage comes at a high cost. Pipe connections are made only at manifolds and water distribution points, which, together with the saving of time needed to complete the installation, allows to compensate the cost of purchasing the manifold and additional meters of pipe.
Another advantage of using manifolds is the pressure equalization at all points. When the flow is opened at one point, the pressure drop in the others is much lower than when using a branch distribution, thanks to which, for example, the troublesome effect of water temperature instability is eliminated. It’s most often experienced when taking a shower and someone opens other cold water outlet which causes pressure drop in cold water line and rising the temperature in the shower.
Sanitary manifolds are used not only in houses and flats, but also in commercial buildings and public facilities - e.g. in hotels, dormitories, public toilets - where an additional advantage is control over individual outlets from places inaccessible to users. In such cases, sanitary manifolds are most often installed next to the domestic water risers and allow for shutting off the flow in only one device or room, thus ensuring the uninterrupted operation of the rest of the system.

When doing installation with manifolds, each distribution point (bathroom, kitchen, toilet, washing machine, dishwasher, etc.) is connected directly with a separate outlet in the manifold, which allows to cut off any point if necessary, without having to turn off the flow in entire apartment or building.
