FIGURE 23.2   4 Way Valve Function Test

4 Way Valve

Check each end cap 

for cracks and for 

major leaks. You 

should NOT use 

leak detector on the 

valve.

Use a 0-30 psi pressure gauge to monitor 

system pressure swings, and also record the 

amount of time it takes to achieve a shift (full 

charge and full purge).
