Frozen | Shower Drain

"I called 'Rapid Rooter' for a frozen shower drain. They charged $450 for a 15-minute visit. The tech just poured hot water mixed with calcium chloride (ice melt) down the vent stack on the roof. It worked, but I could have done that myself. He warned that if the ice had cracked the cast iron trap, it would be $3k. Thankfully it didn't.

"My 5th wheel’s shower drain froze at 10°F. Since I couldn't run a heat cable inside the plastic underbelly, I poured a gallon of directly down the drain. Let it sit for 30 minutes. It slowly ate through the ice plug. Not a perfect fix (it left pink goo), but the water drained again. Deducted one star because you have to flush it 10 times before the smell goes away." ⭐ 2 Stars – "Plumber Emergency Service – Overcharged" By: DesperateInDetroit Date: Jan 2026 shower drain frozen
