The present invention involves a pressurized water treatment system and method having a unitary liner and flange and a plurality of interchangeable heads. The system utilizes non-threaded connections where periodic detachment is desirable to eliminate the cross-threading problems posed by plastic threads. The coupling devices include an improved clamp assembly to removably secure the water treatment heads to the liner flange or other system components and an improved spring clip to removably attach inlet and outlet lines to water treatment heads and fittings. By including L-shaped tabs, the spring clip reduces the chance of inadvertent dislodgement. The use of common connectors allows any of the interchangeable heads to be used with the liner and other fittings. Adapters can also be used to allow non-system components to be integrated into the system. A fill port adaptor can also be disposed between the liner and water treatment head to provide access to the tank interior without the removal of the head.
