I installed a lighting circuit that has two 3-way switches and one 4-way switch. One 3-way switch is leading into the laundry area from the kitchen, the other 3-way is coming from the garage into the laundry area. And the 4-way is at a wall near a door leaving the laundry area, going into the backyard.

Now the problem is that the 4-way seems to be failing often. This will be the second call back on this one switch. Bring the switch count to #3. When we Finished this house the circuit worked, when we replaced it and showed the homeowner, it worked. Now 4 months later same thing.
We are using Pass and Seymour switches and recepticals. And to date this seems to be the only one to really haunt us. Any help out there, has anyone had anything like this happen to them?
