When you have small laundry loads to wash, use the lowest water level in your top load washer to save on water use. You can shave gallons of water off your water bill.
Front load (or top load) high efficiency washers use less water to wash even large loads, but time cycles are adjusted accordingly. You may not be able to slightly lengthen your washer cycle if you have a traditional top load washer, but reducing water for some loads or combining two small similar washloads for some cycles, is a way to conserve water when doing laundry.
You can usually get the same clean washing results with less water. But be careful not to overload your washer and dryer beyond its recommended capacity – that could shorten the lifecycle.
Many top load washers have two to three water levels, so you can reduce water use for each washload. If you’re thinking of replacing your top load washer soon, you may want to consider an HE washer for both electricity and water savings. But understand that these are very different types of washers and the high-efficiency models require more preventative care.
If upgrading to a high efficiency washer is not an option, you can still reap some water savings with your traditional top load washing machine. Check your product manual and make good use of water level selections.
