Every night after my wife takes a shower, what I believe to be our PVC drain will make a quick banging-type noise every half hour to an hour over the course of a couple hours. I will hear it very occasionally in the morning too. It's just a quick bang that lasts less than a second. This only is in our master bathroom shower as well. The other bathroom has never had this issue. It doesn't keep us up at night - It's just more an annoyance.
I don't think it's the supply lines - Every visible supply line in the house I've ever seen appears to have Water Hammer Arresters installed at the source, from the dishwasher to the washing machine.
It's a 3 floor townhouse that's less than 20 years old, however, there were some corners cut here at building time that the original owners didn't believe needed addressing I guess so it wouldn't surprise me that the builders didn't just fasten the pipes and call it a day. It tends to happen more when the weather gets cold. It's hardly an issue in the summer (you might hear it once a night a half hour or so after she showers) but tends to creep up more between September and April or so.
Is this nothing more than the expanding/contracting of the pipe due to the weather?
Cheers
