## Questions & Answers

**Q: How did you wind those on whilst so close to the wall**
A: You turn the radiator nut not the capping tool. Work very well.

**Q: This question was asked but answered incorrectly. How do you use these without water spilling out. Vaccuum doesnot hold all the water in the radiator.**
A: They screw on the threaded nuts on the radiator.

**Q: How do you stop the water from the feed going everywhere? Guessing you still need to drain that?**
A: Turn off the trv and lockshield then put a small container or heavy duty bag under the radiator, take the nut off from the radiator tail then tighten the plumb thumb onto it, do the same for the other side of the rad then lift it off and empty it outside. The flow and return won’t keep dripping if the valves are both off

**Q: you may as well just fit a blanking plug for 50 pence each**
A: if its nut and ring yes but if its 3/4 union face  you carn;t
