Flanges Surrey or York?

I need a flange for the hot water cylinder and it looks like a 22mm compression nut screwed onto it.

I think I need a York flange for this, am I right?

Is that a 1" male thread on the cylinder?

22mm compression thread is a bit of an oddball.

From what I can tell, York and Surrey are both used for (pumped) showers. York is male thread; Surrey female, both 1" BSP (roughly 33mm OD). Is that your application?

I think it's more like a 3/4" npt

I'll have a measure up. :thumbup:

I've got a 1" flange but it's too big for the threaded boss on my cylinder so I'm assuming it's a 3/4" boss?

Or a compression nut for a 22mm pipe and olive which won't be 3/4"bsp. Compression fittings can have course or fine threads and 22mm ones aren't 3/4" bsp. Best to turn off the cold feed to the cylinder, run a hot tap, when it stops running disconnect the pipe and see if it has an olive in it.

I should know, I fitted it :doh:

The new pump is in although I didn't fit any kind of flange as I can't find one that'll fit :dontknow:

Seems to work ok...

Naturally non of the pipes were anywhere near the right place so it's a bit congested. It's very quiet compared to the old one and now sits on a cut up kneeling mat that cost £7.37 instead of about £30 for a branded Salamander one :vsad:
