another thing to keep in mind is that everyone who has installed a SWG loves it and I don't think any of us would consider going back to manual clorination! Also with the rising costs of chlorine (I just paid $1.68 for 3/4 gallon of ultra bleach...for my laundry) SWGs might soon become the less expensive way to chlorinate.
If there is anyone on the forum who is not happy that they have installed a SWG I would sure love to hear it!

In the old forum I remember there were some breakdowns on the cost of installing and operating a SWG vs. manual chlorination and if I remember correctly, the price difference taken over the 5 year estimated life span of a cell was very close.
