I need a longer non-standard tub/shower diverter in a finished tub surround. The threaded nipple I have now is short (works, but spills onto the overflow).
Question: How can I extend that nipple? I can buy a Slip-On Tub Spout if needed.
Can I use PEX because I don't trust my pipe sweating abilities?
Similar to what I have
The existing pipe is already soldered into the value and passes through a recently finished wall.
