How To Replace The Solonoid

How to replace the solonoid on a pool system:

1)  Look at the see-through plastic piece on the solenoid valve.  

2)  Unscrew the little screw from the solenoid.  The solenoid will then unplug from the assembly.  Make sure you do not lose the gasket that seals the solenoid.  

3)  With the gasket in place, plug the new solenoid in and reattach the screw.
