I want to stop my lawn from turning into straw in the hot weather.

There's a threaded water tap in the back wall of my house. I thought
it would be pretty straightforward to put a hosepipe on there, so I
bought a Hozelock 21mm/26.5mm threaded tap connector. I thought the
tap was 21mm, but the connector seems to be slightly too small. The
threads look like they're compatible, but try as I might, I can't
screw the connector on. I've even tried filing its thread down a bit
with a pen-knife, but no joy.

Has anyone else had this problem? Is there a trick to fitting the
connector that I've missed, or do I
have some sort of bizarre non-standard 22mm tap? Would a universal
Hozelock connector solve this problem, or is there something else I
should try?

Any advice much appreciated.

Measure the tap.. with a good rule with both imperial and metric on
it.. Chances are its a 3/4 or 1 inch BSP thread in which case you can
get fittings quite easily.. They are still made as its very still
pretty common to find. I know for a fact that our local plumbers sells
them and so do good Horticultural suppliers such as LBS
www.lbs-group.co.uk

No idea about hoselock measurements but my general impression is that
they are cheaply made and overpriced with few stockists supplying a full
range of the stuff they make. Eg there's never the bit you want on the
shelf!-) Whatever it is there'll be someone out there that makes a
connector I'm sure;-)
