Thanks to everyone for the replies. I have informed my husband it
probably means a non return valve ( which we already have). He nodded. I
suspect he was just trying to upset me because I bought the pressure
washer for him without asking him first.

And so he should be. It makes no sense to be buying
stuff you don't understand if you don't have to.

wummin just don't have the grasp ......
