I am a first time home owner and the spout in my guest bathroom is leaking. I all parts are new and it is a slight leak, but a leak non the less. I have taken the spout off, but I don't know what to look for and have not found anything on line that would fit my particular situation. Not sure why I would have a leak from a spout in a new construction home. Does anyone have any ideas what could be causing this leak?
