Is 40mm the width of the pipe? (not the pipe plus screw fitting)

Mr P, 40mm (1.5") is the diameter of the pipe that this fits, such as is used for baths etc. There is a smaller size which is 32mm (1.25") typically for the pipes used for hand basins. Regards, lim

are these suitanle for outdoor use

yes of course, it is like any other conventional syphons except that it can also be installed horizontally and vertically.Hope this answers your question this time.

Does this work fine with a washing machine without restricting flow, and do they need replacing every x nimber of years or do they work indefinitely?

It'll work fine on a wasing machine as it's wider bore than the outlet hose. Even though guaranteed for 3 years, we've had one for 10+ without problems.

What is the length of this thanks

PM, The length of the Hepvo waste valve as shown in the photograph is 188mm, but be aware that if it is used between two pipes the 'running adaptor' will increase overall length to 208mm. For all the information on Hepvo, try their download site: . There is a useful brochure with lots of pictures, applications and dimensions. Regards, lim
