Nilfisk Backflow Valve Comp. Gardena - Original Nilfisk Pressure Washer Attachment (106411177)

The Nilfisk 106411177 Backflow Preventer has garnered mixed feedback from customers who express concerns about the product's necessity and value. Many reviewers acknowledge the importance of ensuring safe water supply practices, particularly when using power washers that could potentially contaminate drinking water. However, there are complaints about the price point, with several customers feeling that for a small piece of plastic, the cost was disproportionately high. Some users feel uncertain about the actual efficacy of the backflow preventer, as they are unsure whether it is functioning as intended. One customer noted that their outdoor tap likely already had a non-return valve installed, leading to questions about the need for this additional safety device. This sentiment is shared by other users in the UK, where regulations require outdoor taps to have built-in non-return valves, rendering the product seemingly redundant. On the other hand, there are positive testimonials regarding the product's design and compatibility with Nilfisk pressure washers. Users have reported successful installations without issues, indicating that the backflow preventer works as expected in its intended environment. Overall, while the need for the backflow preventer is recognized, its cost and redundancy in certain situations have left some customers wary. **
