## Description

Karcher Pump Adapter with Check Valve – Small Hose Connector for Secure Water Flow & Backflow Prevention : desertcart.ae: Patio, Lawn & Garden

Review: Essential accessory at very High Price - This is an essential obligatory accessory at a very high price I cannot understand WHY Karcher does NOT include it with their submersible pumps like other makes. Removing this important part and selling it at this high cost is a marketing trap for unwary consumers.
Review: Il prodotto è di buona fattura e utilizzabile per portare alla dimensione di 3/4 il tubo di uscita della pompa. Il rischio di avere un raccordo di questo tipo vicino all'uscita della pompa è quello di sovraccaricarla troppo e di romperla. Al momento questo non è accaduto, ma è un rischio da valutare. indubbiamente poter utilizzare un tubo da 3/4 rispetto a quello da 1 pollice permette maggiore versatilità nell'impianto. Perfettamente funzionante la valvola di non-ritorno in plastica.
