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

If these are so needed they should be supplied with the power washer. It seems outrageous to pay the same price as a basic one to safely use your power washer. Mine is a decent one and this was still half the price of it

Difficult to know if this is actually working but have installed on my kitchen tap when using with my Nilfisk pressure washer to prevent backflow into the main water supply. Very expensive for what is essentially just a piece of small plastic.

There is not a huge amount to be said about this product other than it fit my outdoor tap and hosepipe well. The instructions with the pressure washer suggest this is essential but I don't even know if this was a necessary purchase because we might have a double check valve plumbed in already. However, as I have used the pressure washer for drain unblocking, I didn't really want to take the chance. Overall design and build quality etc. are ok but seems very expensive for what it is.

After contacting Nilfisk direct, this product is for outside taps that do not have a non return valve fitted as standard. It is there purely to stop potential backflow from your washer into the mains drinking water supply. All outside garden taps in the UK have to have a non return valve fitted by law, so this is in fact, a redundant item in the UK. Apparently. Hope this helps

Ich weiß nicht ob das wirklich nötig ist, aber sicher ist sicher. Der Druck des Hochdruckreinigers ist halt deutlich höher als der Wasserdruck in der Leitung. Sich irgendeinen Mist aus abgestandenem Wasser in die Leitung zu drücken muss echt nicht sein. Hiermit muss ich mir darüber keine Gedanken machen.

Ho usato questo prodotto per alimentare una idropulitrice e funziona perfettamente.

Va muy bien
