Our Bathmate Penis Pumps are built to last, with powerful construction and a minimum of 2 years warranty on every pump. However, over time, any product can end up functioning less effectively, particularly when it comes to moving parts. One of the most frequently used parts of our penis pumps is the unique locking valve that water passes through when pumping, with this part wearing out over time in some rare instances. We don't want to make you buy a new hydropump if this happens, so we offer Replacement Bathmate Valves for all of our three penis pump ranges.
