Yes, some people still use them. It is one of the methods pump manufacturers state for hot draw off.
The flanges for screwing into top of cylinders are easier to install and no drilling.
Heat eventually destroys the soft rubber washers on Essex flanges

I thought so alright. Thanks again for the feedback. The washers that came with it seem to be pretty thick ones like wine bottle cork stuff. Manufacturer claims it can take up to 120 degrees celsius which would be hotter than a kettle!! Cheers.

That is news to me. The washers are usually very soft white rubber (to guarantee they mould to the curve shape of the cylinder and the uneven surface often caused when it is drilled.
They certainly used to be only suitable for 60 degrees or so.
Once they go hard they can leak and sooner if the pipe gets a knock

Yes I've seen those type online. Creamy white looking washers. Look very dodgy. These hard cork ones are flexible to take the shape of the surface too. Maybe I'll get a bottle of plonk, boil it and see at what temp does a cork start to dissolve!!! Thanks for the quick replies.

You say you leave the immersion alone, how are you going to get the Essex flange inside the cylinder?
I’d definitely use Surrey, or even tee off hot feed half way down cylinder in preference to Essex- but I’m a scardy cat having dropped one in cylinder before....

Sure he can just fit the Essex flange from the drill hole?
That is what it is designed for. The split copper washer covers inside the oversize hole
If anyone was to fit it from an immersion hole, just need a piece of stiff wire (earth wire good) and just use a brass tank fitting with something to seal it and let it thread through the wire. Drill hole then can be tight fit

Yes. That's the route I think I'll take. Have a 38mm bimetal holesaw and will use my own long wire. But original reason for post was to find out if it's ok to have a male iron compression fitting inside the cylinder submerged permanently in the water to attach a piece of pipe to the flange on the inside with a 45 degree angle cut out for air to travel around the pipe and not up it. Thanks again for your advice.

I hadn’t realised that is what you were thinking.
You can use a brass tank fitting if you use proper seals on it, but it will not fit through the top of cylinder unless you use the immersion hole, which is a problem to remove immersion.

Thanks. Will post some pics of the idea I had in mind tomorrow because luckily I have a scrapped cylinder to do a mock up of the connections I have in mind. Cheers
