nope not me still cant see the H section

 

[jase158]

I mean this section, I have always called it H section, I am guessing there is no real name for it, except Feed and vent?

I always thought, feed was pipe coming down, vent was going up, but what is name for this section?

 

[SimonJohns]

That's just a crude de-aeration device. Comman on persimmon homes with gravity fed systems

90% of jobs I go to they look like a H shape.

 

[jase158]

i also call it H section as any systems I have been to that don't have it in the shape of a H, normally are too far away and not piped up right. Only my experience.

What would you call it? is it just feed and vent or feed and vent connection or any other name?

 

[jase158]

and does anybody have any pics?

 

[Billy Bob Bob]

What would you call it? is it just feed and vent or feed and vent connection or any other name?

feed and vent it normally blocks at the feed tee called the neutral point

 

[dancinplumba]

think jase means when pumping down, 'H' section is where feed and vent are taken off

 

[tamz]

Also called a close proximity F&E. Same principle as any other where the feed and expansion should be within 150mm of each other. Commonly done in an H layout if the pump and valves are in the upstairs airing cupboard and the boiler downstairs. Flow from boiler rises to cupboard tees for exp and feed then drops through pump and valves.

You can still buy air seperators which configure the pipes in a similar method. They work by slowing the velocity of the water as it passes through.
Look up Aerjec or Tower air separator. BES sell them.
