Bill Margold's company makes a gadget that purifies water right out of the tap (or showerhead). His ace salesmen all realize that demonstration is the best way of selling — and herein lies the tie-in for just about all the sex scenes. While the only well-known lady is Ona Zee, who gets the finale, excellent performances are also given by Pearl, who's mounted by Dick Nasty in various places around the bathroom; Celeste, who energetically takes Joey Verducci to bed without even a tree soft water sample; and Courtney, looking delightfully cherubic as she takes it doggie-style from Arny Schwartz. Sad to say, newcomer redhead Traci Prince just hasn't got the moves yet. Fans of the cowgirl position will find it in abundance here. How unfortunate the editor saw fit to overdub the hottest action with overbearing music, which considerably lowered the rating. Good selling points are the hot-looking box featuring Courtney and the long running time.
