Abstract
In an improved showerhead a bulb portion having a channel for receipt of water therethrough, there is provided and a threaded collar for removeably coupling the bulb portion to a water supply source together with a housing comprising an outer housing portion and an inner housing portion in threadable relationship with one another and having a first O-ring disposed circumferentially about the bulb portion and proximate to the bulb portion channel. The inner housing portion has a front plate portion having a second O-ring disposed peripherally thereabout and between the same and said outer housing portion such that the second O-ring exerts a friction against rotational movement between the front plate portion and the outer housing portion, which is greater than the friction exerted by said first O-ring.
