Review: Ne fonctionne pas. Raccords achetés pour pouvoir installer l'article. Hop.... Encore un achat effectué par erreur. Confier le sort d'une pompe hydraulique à un système à 14€ relève de l'erreur de reflexion !!!!!!!!!
Review: No es así - "Cuando se abre el grifo, la presión disminuye, el interruptor se encenderá, después de cerrar el grifo la presión alcanzará un cierto nivel que se apagará." Porque no es un presostato. Es un interruptor que detecta flujo de agua. Enciende cuando hay flujo, apaga cuando no. Nada que ver con presión.
