I understand it is a boring subject, and that it must have been covered before, but this is a specific request rather than recommendations.
The connector from my pump to my hose reel is a miscellaneous connector (Hozelock are too expensive for the same and I was told to stay away from brass fittings) which on a good day may drip a little with the motion of the reel going round and on a bad day really starts to do my head in!!
The rubber seal on the reel seems okay and I know it hasn't always been the same as it seems to be, anyway I replaced the connector and it's still the same.
Wish I could put a jubilee clip onto the bare hose but then the reel wouldn't turn!
Thankfully a small problem, it's just annoying now we don't have the summer sun to dry out any spills in the back of the van.
