I keep a close eye on water usage not because there’s a shortage here, but because my Culligan tank (which gets exchanged weekly) will soften only about 600-700 gallons of water. This is why I use the water-saving Normal/Eco cycle whenever feasible. Problem would be solved by purchasing a front-loading machine (the LG 3900 is my current fave) but am now on a fixed income and consequently less inclined to ditch a perfectly fine two year old SQ top-loader.
The SQ set may just be the first laundry pair I keep for its full lifespan. In fact, they will probably outlive me, LOL.
As for bringing back suds-savers, I grew up with one so the concept is perfectly normal to me. However, I’d rather have a modern HE front-loading washer. You get the twin benefits of reduced water consumption with fresh water for each load.
