Powdered or liquid detergents -- septic tank
I've read so much here about advantages of powdered laundry detergent, I was genuinely surprised to see dissenting advice about this issue mentioned in Heloise's newspaper column last week.
In that column, someone wrote to say they had had a problem with their septic tank, ended up having to get it pumped out, and when they did, there was a mass of clumped-up powdered laundry detergent in it -- it had not dissolved! They said the guy who cleaned out the septic tank told them to only use liquid laundry detergent -- that it would not cause this problem.
We have a septic tank. I'm sure others here do, too. What do you think about this?
I have noticed there have been times powdered detergent in the dispenser did not fully dissolve, but left a residue. For this reason, I've been putting powdered detergent directly in the washer drum before adding laundry. I also only use powdered detergent in hot water. Do you guys think this is sufficient to prevent septic tank problems? Should I call a septic tank company and ask about this?
I'm sorry I don't have a link to that newspaper column.
