Hi Kddrnhall...

I'm afraid we will need more in formation on this, OK?

What pipe? What valve/faucet? Hot or cold water... or both leaking? Is this a shutoff?

Let us know...

Mark

how do i get the washer off the pipe so i can replace it with a new washer and nut
Not having any information about what type of valve we're talking about we need to know the type of faucet, its brand name, its age and any other details that you have. Back to you, Tom
