Why it matters
Rough-in plumbing is the foundation of your entire plumbing system. Proper sizing, venting, and layout ensure your home passes inspection and performs correctly for years to come. Mistakes at this stage can lead to costly issues later, which is why we take the time to do it right the first time.
