noisy pipe no leak & vent location
1) Long story short but my plumber installed a vent pipe under the soffit of my dormer. The dormer is purely decorative and the soffit is unvented and actually does not even open up to the attic space or livable space. The vent pipe is about a foot below soffit. Is there a problem with the gases hitting that soffit, i.e. deterioration, green looking paint etc.. I know I should have had it moved but at the time that was the least of my issues.
2) When my plumber installed one DWV pipe, I believe the strap used to secure the DWV pipe was set to tight, because when I turn on the shower/tub/sink in the master bath there is a massive amount of ticking/clicking noise for 2 minutes while the ABS expands. I have ruled out leaks as the addition has been up for 5 months. Only other thing is a pex line but even when I pull stopper on tub the water going down the drain makes that pipe click or when I use cold water too. It is pretty annoying and I have a pretty high tolerance. My question is; I have an access hatch (that I created) through the tub deck and I can cut that strap to loosen it, is that where you guys would start before you would start demoing?
