Installing the flex hose and hand shower
1 - If major work is done on the home, the water network must be flushed of all impurities to avoid damaging your mixer.
2 - Check the proper placement of seals in the hose. If they are missing, add a fiber or rubber seal.
3 - Screw the smaller end of the hose onto the unit.
4 - Screw the larger end of the hose onto the hand shower.
