Hello.

Buying a new machine. Over the last 10 years I have plumbed two 4 at 4 machines together to get a grand total of 8 GPM at 4000 psi. Im tired of the issues associated with plumbing two machines together. Im debating on a 10 GPM at 3000 PSI VS. an 8 GPM at 3500 PSI.
This machine will be for flat work only, to clean your average residential type driveway.

I have a HydroTek hot water machine for gum and oil jobs.

What is your opinion?
