My holding tank alarm just went off.
This is the first time it has been full with "normal" water usage since starting to use the front loading washer.
It has been 6 weeks and a day since the tank was last emptied. Previously, it had almost always been exactly 5 weeks.
This pretty much means one less pumping of the holding tank per year; about the same cost as the difference in price of what I bought the new machines for less selling the old ones.
I also did the math on our water usage. It comes to 23 gallons per person, per day. That sounds like a lot. I tried to find information on the "average" American water usage, and found numbers ranging between 70 to 170 gallons per day.
I like being below average!
