To adjust the bypass valve.
The easist way is by hand. Find the valve. It is the large bold like feature with
a red ring. Once locates turn the valve counter clockwise. This frees up the jam nut to turn. This nut is located at the
back of the valve and is about 1/8" thick. Then turn the jam nut clockwise to get it inward so the valve can turn inward.
Adjust the valve clock wise until you get the desired pressure. Then rotate the jam nut back up snug against the valve.
