- close the water faucet and relieve pressure from inside the supply hose by unscrewing one of the pipe fittings.
Remove both supply and drain hoses and let all water drain. Before using the hoses again, following a long period of
inactivity, check for any damages or cracks and replace, pipe fittings’ gaskets if necessary.
