My clients asked me if the new home they are buying will adequately support the newer front-load washer and dryer combo units. They said the front-loading units weigh up to 100 lbs more than conventional units. It is my understanding that vibration can be felt if the units are not levelled properly. In my experience, walls, floors and ceiling coverings such as sheetrock and floor sheathing that were glued down in addition to being nailed or screwed will cause the interior to be more rigid, thus transfering vibrations to other areas of the home.
Levelling is key. Regarding making a determination if the floor is adquately supported, does anyone have a quick formula or chart to determine how much weight a floor can support in an 18’ square footprint area where 2"x10" floor joists on 16" centers were used? Figure on the units weighing up to 200 lbs each. Thanks.
