NO DRAIN POINT

[Mike2007]

Yep some idiot hasn't added a drain point when the heating system on a back boiler (solid fuel) was made!
No the pipework in wall is leaking slowly.
How do I drain off slowly are there any gadgets for this on 22-28mm copper pipe?
No rads to use as a drain point either, just back boiler to cylinder

Just crack a compression nut somewhere and wet vac it out. There won't be that much water if it's just doing a coil. Don't forget to isolate supply to F&E tank.
