My 42 1.5 ton does not have a check valve in the vac line. How bad is this and what should I be checking for, for proper ops of the system? Where can I get a check valve ?
Thanks for any help
I know that there have been some threads on hydrovacs here so if someone could post the links I would like to read up on them.
