Every powerwasher operator should have this gauge. Using this on a brand new system will allow you to know if you have the proper tip for your machine and if your unloaded and pump are performing up to spec.
This gauge is very easy to use, well made and is a necessary plus for evaluating proper operation of your pressure washer especially after replacing your units unloader valve.
Very large heavy gauge for 3100 pressure washer, good for outlet pressure regulation for the unloader valve bypass adjustment.
good price and as shown
I liked how easy it was to install and the fact that it works beautifully.
