Rocky Mountain Goods Sink and Drain Plunger is the perfect plunger for unclogging slow drain, tubs and showers. Many people will try to use a toilet plunger to unclog drains but will find a toilet plunger is too large to apply pressure to unclog the drain. Our drain plunger is made with a 4” rubber force cup head that precisely applies pressure and unclogs your drain. Like all Rocky Mountain Goods products this sink and drain plunger comes with a lifetime warranty.
