Claim:
1. A pressure spike reducing apparatus comprising: an outer housing; an interior housing disposed within the outer housing, the interior housing comprising a substantially cylindrical body having a first diameter, the body having an annular shoulder at a first end forming an aperture with a second diameter smaller than the first diameter and the body having a second sealed end; a fluid channel permitting the flow of fluid through the apparatus from an upstream end and out a downstream end, wherein at least a portion of the fluid channel is disposed in an annular space between the outer housing and interior housing; a piston disposed within the interior housing in a first position when no pressure spike in the fluid channel is occurring and configured to temporarily move to a second position within the interior housing in response to a pressure spike in the fluid channel; a sealed pressurized chamber disposed within the interior housing between the piston and the sealed end, wherein the pressurized chamber has an internal pressure that is only adjustable by movement of the piston within the outer housing; a first connector comprising a substantially cylindrical neck disposed at an end of the apparatus and a second connector comprising a substantially cylindrical neck disposed at another end of the apparatus; and wherein each connector is configured to selectively connect the apparatus to a pipe, flexible hose, valve, or semi-rigid PEX riser to permit the flow of fluid through the fluid channel; and wherein at least one of the connectors is integrally formed with the outer housing or the inner housing or both.
