After prepping my veggy bed for the new season I found quite a few sprayers had broken off.
In the past I had one or 2 and these I simply used a soldering iron to seal the hole and drill a new hole and install a new sprayer.
I do not have that size "Easy-Out" hole is about 2mm.
I took a chance to use a 3mm glass/tile drill and placing just enough pressure on it not allow it to slip managed by using my battery drill in reverce to remove all of them successfully
And a new sprayer installed in the same hole.
