## Description

McAlpine ARB-1 Anti Cross-Flow and Rodent Barrier Valve, Black

Review: Preso per disperazione causa continui riflussi di acque nere. 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 ! Ich habe ihn schon zwei mal gekauft !
