Installato dal pozzetto d'ispezione. Facilissimo da inserire (e questo mi ha stupito) per misure standard. Per sicurezza ho siliconato tutto attorno ma sembrava stabile anche senza. Posizionato in orizzontale, funziona perfettamente. Monitorerò comunque nelle prossime settimane. Review: Guter Artikel !
