Should I Use Bleach To Clear My PVC Drain Pipes?

There is confusion about the use and safeness of Clorox bleach in your HVAC system. For decades many ac contractors told their customers that it was ok to use bleach to blow out their drains. That bad advice has spread like a virus worldwide. The problem with bleach is that there hasn't been much debate on how it damages PVC pipes. When students go to technical school it's a subject that is somehow not talked about by the instructor. There is no chapter in the HVAC books that suggest Clorox bleach is an excellent solution to flush your lines. People still do it because it still works, but it is only a short-term solution. It usually takes about 20 years of pouring bleach down your drain lines to damage them. Pvc pipes become hard and brittle after many years bleach. The problem gets worse when people have horizontal drain pans in the attic. People are pouring beach in the emergency drain pan. The emergency drain pan is also known as the auxiliary pan is made of galvanized metal. Pouring bleach in that drain pan only once a year will destroy it in 5 years. You will then have to call a professional ac company to replace that drain pan.
