Item does not hold pressure and item does not function with a pressure leak. Customer service is way too strong against helping when the defect has been presented to them. I am seeking a refund since a replacement has now been purchased elsewhere.
VIDEO CLEARLY SHOWS ALL VALVES ARE SHUT, ALL CONNECTIONS ARE TIGHT AND PRESSURE DROPS AFTER EBING PRESSURIZED WITH PUMP.

For this pump,the correct operation step as follow:1,open the relief valve and stop valve by rotating them counterclockwaise;2.install the gauges,PLEASE DON'T USE THE WRENCH TO TIGHT IT,THIS WILL DAMAGE THE DEVICE!!!3.close the relief valve by rotatng it clockwise;4,lifting and pressing the handle to increase the preasure;4.after the pressuer value is arrived to the point you required,please close the stop valve to make the pressure value is stable.
from your video,there have two problem when you operate it.First,after you install the gauge,just need tight it by hand,but YOU USE WRENCH TO TIGHT IT FORCIBLE,THIS MAY DAMAGE THE PUMP;Second,after the pressure value is increased to the point you need,you didn't close the stop valve for make pressure stable,hope you can operate it according to step above and take a video to us to check it,we really want to solve this problem with you,thanks for your kind understand and cooperation.
