<i><b>Not able to see your set-up, I&#39;d say that all that would be needed is a good pair of pliers. The new washer comes with a new hose ??? Shold not have to replace the water valve as it is only a faucet. If the new washer doesn&#39;t come with a new hose, then a new hose washer may be needed to curtail the leak. In any case I suprised the the company that you bought the washer from didn&#39;t hook it up.<br /><br />Good luck<br /><br />Later<br />Jim</b></i>
