While changing the wall sink valve, one value started leaking. Determined that the brass compression nut was cracked and the value was leaking. How do I get the compresison nut off and a new one on?

Hi jaxboy:

You probably need to purchase a combination handlepuller/compression nut remover tool... see pic.

Do not purchase JUST a handle puller... will not do the job! Must be a combo. Puller.

Basically, the ears fit behind the nut, and the tip fits over/into copper pipe, then twist handle and should pull the sleeve off.

These tools are available at all home supply stores.

Good luck... MARK
