I have fitted an inlet valve (bottom entry) to a WC cistern to replace the original that was leaking at the connector. This valve was an exact copy of the one it replaced with plastic arm and ball etc. After connection and refilling a slight leak was evident from the nut where the valve is secured to the cistern. I tightened the plastic nut a little more but was reluctant to turn it beyond the recommended 3/4 turn with spanner. As this did not stop the leak I decided to replace the valve instead with a torbeck type as these have a more tapered washer and more inclined I would think to provide a better seal. Having done this and tightened as specified in instructions the leak still appears around the sealing nut.
The WC itself is pretty old, I imagine circa 1970's. Could it have become porous with the recent moving etc. There is no noticeable chip of the ceramic on the inlet hole and I really cannot see any hairline fracture on either the outside or inside. Is there any type of sealing compound that could be used etc? Any comments appreciated. Thanks.
