Expansion Tank/Cylinder

[Freddie]

Where should the lead off the piework be for the expantion system?

Should it be after the boiler before the rads or should it be on the the return pipe before the boiler?

It was something that came up in a conversation---i would have thought it would be up to the tank off the return before the boiler but a plumber told me he always did his straight after the boiler infact the first t'off

 

[kevplumb]

Scruff was right about you icon_smile.gif

yup

 

[Freddie]

so none of you plumbers know then?

 

[kevplumb]

expansion should be on the flow side and permanantly open

i fitted a universal expansion vessel just last week. a replacement for a knackered one. it was fitted on the return just before the boiler.
also the instructions stated to fit it there.
cooler water i guess harms the rubber less. (and it works a treat now !)
