Thetford Porta Potti 320/550 storage and maintenance prep

Use the Thetford Porta Potti 320/345/365/550 support page to capture model, storage, cleaning, battery, and seal-lubricant details.

Owner-safe checklist

Record the Porta Potti model, especially 320 or 550, plus flush type, level indicator state, battery condition if present, and exact symptom.
Use only Thetford-supported cleaning, storage, and seal-lubricant steps from normal owner access.
Save photos of labels, tank latch condition, level indicator, and visible seals before support.
Use Thetford support or qualified RV sanitation service for parts, leak, electric-flush, or damaged-tank decisions.
