i recently changed three switches that control a ceiling light. i replaced them with two 3-way switches and one 4-way switch. the switches work at times depending on which switch i used last. for example, if i turn off the light with one switch, i can turn it off using a different switch. however, i can't turn it back on unless i use the same switch that i previously turned off with. there are four wires that come out of the wall to the 4-way switch and 3 wires for the other two 3-way swicthes. does anyone know how i can fix this problem without contacing an electrician? also, is my problem limited to the wiring for the 4-way switch only?

Hello all. We just had a new inground pool installed. The pool company takes the conservative approach and says run the pump 24/7. In discussing the issue with other pool owners on a pool forum similar to this board, there is no real consensus amongst owners/installers. I know there is the issue of on/off cycles vs. continuous run times and the related wear issues, but for sake of discussion, I'm trying to simply determine the cost to run the pump. The name plate ratings are: 1 HP pump with a service factor of 1.25 (I think this means the pump is effectively producing 1.25 hp. Is this correct?) 230 v/7.1 amps Now here is where I get confused. One HP is 746 watts. Applying the service factor, I get 746*1.25=932.5 watts. If I multiply the nameplate ratings, I get 230*7.1=1633 watts, a far cry higher that the earlier answer. (Also, I know I'm running at 240 volts, not 230, but presumably the current is correspondingly less than 7.1 to still equal 1633 watts. Correct?) My cost per KWH of electricity is about 0.085. So for a 24 hour period, I should be paying: WATTS/1000 * 0.085 * 24= Cost If I use these two numbers, I get either $1.90 or $3.33 per day or a ~$43 difference per month. I have no problem running the pump as necessary to do the job; just don't want to throw money down the drain . Thanks in advance. Rob
