Thetford Porta Potti 555/735 flush and storage prep

Use the Thetford Porta Potti 555/565/735 support page to capture flush, storage, cleaning, battery, and seal-lubricant details.

Owner-safe checklist

Record the Porta Potti model, especially 555 or 735, 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.
