Product Questions
Answered by Jim. the Pressure Washer Expert
Mike
I have a Troy Built 6.75 HP (model 01904). Would this pump be a good replacement for it? Do you have any other recommendations? We use it just around the house and barn so it's not used a lot but at times can run for several hours on a job.
Thanks
