There is usually water overflow during this process. Please prepare a cleaning device such as a basin or towel:
a) turn off the plating ball valve and pressure barrel ball valve;
b) Open the gooseneck faucet to remove residual water from the pipeline;
c) After the water is no longer flowing out, use a filter shell wrench to open the filter housing with the filter element;
d) remove the old filter and load a new filter of the same specification;
e) Apply a black “O” ring above the filter housing to a lubricant such as Vaseline, and place the “O” ring into the groove in the filter housing.
f) In a vertical manner, tighten the filter housing to avoid shifting the “O” ring.
g) Open the plating ball valve and pressure barrel ball valve.
