Frequently asked questions
-
Es una válvula antirretorno que deja pasar el agua en un solo sentido. Evita que el agua de la instalación vuelva hacia atrás y contamine la red de suministro con solución nutritiva o restos de fertilizante.
-
Entre la toma de agua de red y el depósito o el sistema de riego. También se coloca a la salida de la bomba, para que la columna de agua no retroceda cuando esta se para.
-
El cuerpo de la válvula es de latón, con rosca de 1 pulgada. Se sella con cinta de teflón para asegurar una unión estanca.
-
No, esta válvula es de 1 pulgada y no es sustituible por una de 3/4. Comprueba la rosca de tu instalación antes de pedir.
-
Porque sin ella el agua con solución nutritiva o restos de fertilizante puede retroceder hacia la red de suministro y contaminarla. Con el paso en un solo sentido, ese retorno queda bloqueado.
