double p.s.i

[cvpw]

I have heard from a couple places that you can tie 2 machines together and get double the p.s.i and gpm. so if you have 2 3000 machines you can actually get 6000psi with some type of attachment.
Has anyone here done that to their machines???? Do you recomend doing that for large concrete jobs? Where can I purchase the coupler for the machines?
Any comments or suggestions would be great.
Thanks

True and False

The volume part is true but the pressure part is FALSE.
The two pressures will equalize and the actual pressure will be the sum of the two devided by two.
