A cleaning fluid introduction device (10) comprises a hose portion (12) and a body portion (14). The body portion comprises a flow adjuster (16), a bottle attachment section (18), and a hose receiving section (20). A pressurised canister (62) containing cleaning fluid is placed in the bottle attachment section (18). There is also a cut off valve (60) provided to cut off the supply of cleaning fluid from the canister (62) when the device is not in use. The cleaning fluid is fed to the flow adjuster (16) from the canister (62) through a channel (34) with the cut off valve in an open position. The cleaning fluid is forced through the device by virtue of it being pressurised. The fluid is then fed into the central heating system, most conveniently through the drain cock of the heating system, which is usually at the lowest point of the system. |
