the second or closed position the pump 102 fills with water until the pressure is equalized between the water pressure in the faucet 112 and the water pressure in the pump 102 the pump 102 is activated or pumped to increase the water pressure in the fill hose 108 and force water back into the faucet 112 if the pump 102 is a diaphragm pump then a handle 114 may be used to pump the pump 102 and increase the water pressure in fill hose 108 water is forced back into the pipes within the house via faucet 112 in a direction opposite in which the sediment was formed in the fixture the force of the water pressure going in generally an opposite direction aids in the loosening and freeing of sediment in the fixture the use of a hand powered pump aids in limiting the pressure that is built up in the fill hose 108 and water pipes located within the home or other building to flush out the sediment that has been loosened a user opens or places the on off valve 106 in a first position the sediment is then allowed to flow through the fill hose 108 from faucet 112 through valve 106 and exit through the discharge hose 110 the household water pressure provides the force to flush the sediments out of the faucet additionally one end of the fill hose 108 may have a fitting 116 that enables.
