Start With the Fit: Rise Settings Matter
If your Rumparooz One Size cloth diaper cover is leaking, the first thing to check is whether the rise is adjusted correctly. The cover has four adjustable rise settings and fits babies from 6 to 40+ pounds. Snapping the rise to the wrong size can leave gaps at the legs or waist, which is a common leak path.
Check that the diaper cover is snug against your baby's body without being tight. The cover is designed to go over a flat, prefold, or fitted diaper, so make sure the absorbent layer is fully contained and not peeking out at the edges.
What the Cover Is Designed to Do

Rumparooz One Size Cloth Diaper Covers - Novela: The Rumparooz One Size Cloth Diaper Cover has 4 adjustable rise settings and fits babies weighing 6 to 40+ pounds. If the rise setting doesn't match your baby's size, the cover may not seal properly, leading to leaks.

Rumparooz One Size Cloth Diaper Covers - Novela: You can even use it over most fitted or prefold diapers. The cover is a waterproof shell, not an absorbent layer. Leaks often happen when the absorbent diaper underneath is saturated or not positioned correctly.
Wash Routine: A Common Leak Cause
A buildup of detergent, minerals, or bacteria can cause repelling, where liquid runs off the cover instead of being absorbed. The supplied care instructions recommend a specific wash routine: 1 cold rinse, 2 hot washes with the right amount of detergent, then 3 cool rinse. Tumble dry low or lay flat to dry in indirect sunlight.
Avoid laundry additives like bleach, Oxiclean, Borax, or Bac-out, as these can damage the eco-friendly bio-TPU lamination and reduce waterproofing. If you suspect buildup, try a reset wash with no additives and check your detergent against Kanga Care's recommended list.
Quick Leak Troubleshooting Steps
Use these steps to isolate the cause of a leak in your Rumparooz One Size cover.
- Check the rise setting: Snap the cover to the correct rise for your baby's weight. A too-large rise leaves gaps; a too-small rise can cause compression leaks.
- Inspect the absorbent layer: Make sure the prefold or fitted diaper underneath is fully inside the cover and not twisted or bunched. Saturation of the absorbent layer is the most common reason for leaks through the cover.
- Review your wash routine: Follow the 1 cold rinse, 2 hot wash, 3 cool rinse cycle. Use only recommended detergents and skip additives that can harm the bio-TPU.
- Check for repelling: If water beads up on the cover's inner fabric, it may be repelling. A hot wash with detergent (no additives) can often fix this.
When the Cover Itself May Not Be the Problem
The Rumparooz cover is a waterproof shell, so leaks usually originate from the absorbent diaper underneath. If your baby is heavy wetter or you're between changes, consider adding more absorbency to the prefold or fitted diaper. The cover itself does not absorb liquid; it only contains it.
If you've ruled out fit, wash routine, and absorbency, the cover's waterproofing may have been compromised by heat or additives. The supplied evidence notes that bio-TPU is eco-friendly and heat-bonded, but it can degrade with improper care. In that case, a new cover may be the simplest fix.
