Poor flush or rim wash may be caused by obstructed rim holes in the toilet. Follow these steps to rinse rim holes with a hard water deposit or lime dissolving cleaner.
- Shut off the water supply to the toilet and flush it to get rid of most of the water (Fig. 1).
- Ream out the rim holes. Use a paper clip or a finishing nail to clean difficult obstructions in the rim holes (Fig. 2).
- Use wet paper towels to block the rim holes and plumber's putty to keep the towel in place (Fig. 3).
- Pour a hard water deposit or lime dissolving cleaner into the rim inlet in the flush valve and let it sit in the rim chamber for 8 - 24 hours to dissolve the deposits. It is recommended to lift the flapper or canister and pour the cleaner directly into the flush valve hole (Fig. 4).
- After 8 - 24 hours, remove the towels and putty, then flush several times before using.

Likely causes:
- During shipping, pieces of vitreous can shake loose and settle in the rim holes.
- Hard water deposits can also restrict the water flow through the rim holes.
