Essex flange again

I don't know much about Essex flanges but I've messed about with a few Essex girls in my time.

All those white shoes and handbags! When they took you home did the swirly patterned carpets make you sick? Was the floor moving when yoiy lokked at it?

I've never used one, but my understanding is that you have to cut a hole in the cylinder to take the flange - possibly an elongated rather than circular hole. I guess that the base of the flange then goes in through the hole and is rotated so that it cannot come out again. I guess that there is some sort of sealing washer which also has to be fed in through the hole, and then a big nut on the outside to hold it all together.

There is also something called a Surrey Flange - which does the same job except that it shares the main hot takeoff on top of the cylinder with the original hot outlet pipe. You don't have to make an additional hole for these - but they do restrict the flow somewhat because two 22mm pipes are sharing one 3/4" boss.

If this is all rubbish, I'm sure someone will say so!

It has to be circular. Instructions come with the flange.

It doesn't. An Essex flange is a tapping into the side of a cylinder.

Unfortunately, most is rubbish.

As an aside to this discussion, could somebody explain why plumbing parts are named after English counties ?

My first such encounter was with Yorkshire fittings, which the obviously Lancastrian descendent in the plumber's merchants explained that otherwise those on the wrong side of the Pennines wouldn't know where to put the solder.

Ah, but you're confusing *what* it does with *how* it does it!

They both do the same job in that they both provide a shower takeoff from a point some distance below the top of the cylinder. Whether you go in horizontally from the side or vertically from the top is immaterial - except for the slightly restricted flow of the Surrey flange which I mentioned in my earlier post.

With regard to my earlier post being mostly rubbish, I will leave others to judge on which of us has the better track record for sensible posts!

They can be towns as well. Ballvalves have names like Portsmouth and Garston.

To clarify for you. An Essex bosse is a tapping in the side of the cylinder. They are used for many purposes. One is a shower take off, others are flow and return connections.

A Surrey flange converts one tapping into two. You can use these two tappings for what ever purpose you want.

Maxie, also the tango.

Yorkshire are named after the Yorkshire Imperial company.
