• Turn the valve (
I3

• Once the valve (

• Put solvent into the groove in the ball’s seating;
• If the quantity of solvent a few minutes later is still identical
to that added previously, the ball’s seal in its seating is ensu-
red;
• If the solvent flows out the holes at the bottom within a few
minutes, replace this valve with a new one;
