Radiator bleed screw
whilst bleeding my radiator i have managed to over tighten the bleed
screw and snap the square end off the rest of the screw. to try and remove the rest of the bleed screw i have used a drill and some screw extractors but have been unsucessful in doing so. the type of radiator in question is an old type round topped radiator which does not have the facility to use a spanner to bleed the radiator. what i am wondering is if anybody has come across this problem before and what have you done to resolve it? |

We had this one recently and my idea was to abandon the broken one and just fit a new bleed screw in the other end of the radiator. Bob |

Hi Hogie, No drilling and tapping needed just take out the blanking plug and fit a complete bleed screw assembly. Thread is usually 1/2" BSP but there are other sizes here http://www.toolstation.com/search.html?searchstr=69952 and you will need a little ptfe tape to seal it too. hth Bob |

Radiator bleed screw
In an earlier contribution to this discussion,

If it's a flat surface, you may be able to drill and tap it and fit a bleed assembly. The smallest one listed in http://www.toolstation.com/search.html?searchstr=69952 [No: 91015 - 1/8" BSP] would be the best. You can't just drill and tap for the centre pin because it would have no seat to seal against. If there isn't a flat surface at the end, you could drill and tap the back face of the radiator, just down from the top. It's a bit awkward bleeding it in that position - but not impossible. Indeed, some modern radiators have the bleed screw factory fitted on the back! -- Cheers, Roger ______ Email address maintained for newsgroup use only, and not regularly monitored..
