Removing the valve bonnet
13. Slowly remove the valve bonnet. Note: The spring for the
plunger is located directly under the bonnet and may come
free if you are not careful. Remove the plunger, spring and
valve bonnet and place to the side.
Removing the O-ring
14. Remove the O-ring and inspect it. If it has any tears or cuts
or excessive flat spaces, it should be replaced.
15. Examine the threads for the valve bonnet. Check them for
scoring or signs of damage. Take a cloth and clean them out
to remove any foreign particles that might get lodged in the
threads and cause a leak. Severely damage threads should
not be repaired; instead it is recommended that the entire
valve should be replaced. These instructions do not provide
information on replacing the solenoid valve.
16. Note: Even though an O-ring may not appear damaged, it
is a good idea to go ahead and replace it if you have a new
one. This will help ensure that your valve remains leak-free in
the future!

Removing the diaphragm
17. Remove the diaphragm retainer and then the diaphragm
itself. Many problems associated with a solenoid valve can be
traced to a clogged pilot port in the diaphragm.
Pointing out the extension hole
18. As indicated in the photo above, the extension hole can
become clogged. If it is difficult to clean out, you can use a
heated straight pin to push through the hole. The center hole,
the pilot port, must also be clear. If the diaphragm is torn or
bent in any way, it must be replaced.
