Toilet cistern float ball / fill valve repair I’m looking for someone to fix a problem with the float mechanism inside my toilet cistern. The existing float ball appears to be too large for the cistern and is catching against the internal sides, preventing it from moving freely and the cistern from refilling properly after flushing. I’d like someone to inspect the mechanism and either replace the float ball with a more suitably sized one or fit a compact fill valve if necessary. Ideally, someone who can supply the replacement part and complete the repair in one visit.
