I recently replaced a leaking (split) hose to the washing machine. I purchased metal (?) instead of rubber hoses. Now the hose is leaking at the part where the hose is joined to the connector. It isn't leaking from connector to connector, as in it seems to be tight enough, but it is the hose itself that is leaking. The rubber washers are in place. They leak more when the water is flowing to the washer. Help.
