Job # 29681-E Service Call – Post Sewer Backup Assessment Customer reported a sewer backup reaching approximately 4 inches; visual inspection suggests actual water level was closer to 3 inches in the furnace and water heater area. No signs of water intrusion above the rim of the condensate pump—unit was unaffected. Blower motor wheel also unaffected; no water entry observed. Furnace Findings: Bottom of the furnace and side insulation were wet with sewer-contaminated water. Return boot also exposed to contaminated water. Recommend replacing or sanitizing affected insulation and return boot components. Furnace is currently operating normally. Water Heater Findings: Pilot light was out upon arrival. Inspected burner and pilot area—no signs of water penetration. Pilot tubing was clear; successfully relit pilot and confirmed burner operation. Some rust noted at the bottom of the water heater, likely due to age rather than the recent incident. Water heater appears to be functioning normal
