Hey everyone, it has been a while since I have contributed anything worthwhile so I figured I could help this way. Over this summer I recently got a new job in plumbing. I have put around 200-300 hours into plumbing so far and I would like to share the knowledge I have learned. If you have any questions on plumbing just ask them here and I will reply and add it into a list on here so you can CTRL+F to see if your question has already been asked. I will do my best to answer it the most clearly and in an easy to understand way for beginners along with anything you may need. You can ask any question related to construction but I only personally know plumbing and bits and pieces of the other jobs. Anyway, ask away.
(Mind you, I am an American so my answers will be to my region specific and may or may not vary depending on where you live depending on regulations and such.)
