hi
ive had the same ez snap on the end of hose for 1 year now, no leaks , i used to use one with a tap/ protecta ball but this used to leak after a while , it was to heavy/long for protecta ball to keep ez snap from knocking on ground whilst reeling in, i now use a trigger so do not need a tap , if you still want to use 1 it is prob. better to fit to pole hose, and have ex snap / protector ball on hose. i have also cut a finger of some old rubber gloves put a hole in and fitted via a cable tie to hose ,so it forms a skirt over ez snap to protect and stop dirt getting in, it also mean i can reel in without it getting caught up.
