Hello everyone. Its been a long time since I posted anything. Been under the radar for awhile. I have a 2012 Cyclone 4014 and my shower is draining slowly. I purchased a wand at Home Depot and it helped clear the clog but now just a few weeks later it is back to draining slowly again. My question is, can I pour liquid drano into the drain or will this hurt or damage the plastic pipes and/or holding tank? Any other ideas on how to clear the shower drain?
