Hmmm, pays to engage brain first .... if a plunger type pump didn’t have a non return valve I guess it wouldn’t be a pump!

SO, reading your question again Graham, I assume you were asking “DOES the Facet block reverse flow?” 

I cannot categorically say but I am 99.9% sure it does. If it didn’t, I don’t know how it could pump.  Judging by the noise it makes notwithstanding being solid state, I can only assume the noise is made by the valves opening and closing. 

Cheers

 Hello Graham,

 Not exactly sure what you mean by ‘reverse flow’ but whether or not it has a non return valve I don’t know sorry.
