This time environmentalists are wrong.
I'd like to report the down side of water conservation appliances.
In the past several years my husband and I have replaced two standard toilets with low-flow units. In addition, we have bought a new washing machine and new dishwasher. Yes, we're saving water. But, here's the bad news: because of the now-reduced water flow to our septic tank, we regularly clog up the line with toilet paper and have to tear apart the piping to break up the dam.
Even using cheap, lighter paper and being careful, we cause back-ups. It's not pretty. I hate to think of a new $20,000 engineered system!
