Having to re-locate expansion/feeder tank as head height is insufficient for new boiler...vent pipe (off which the feeder pipe is teed) currently runs vertically off the flow pipe and up over the tank...will have to cut it down and put a horizontal run on it and then up again to new tank level - any issues with doing that?

use slow bends. not 90 degree elbows.
Ahhhhhh!!..there is always something isn't there!... Can probably cut of piece with slow bend on it and fix it further up (as I haven't got a pipe bender)....what about the 15mm feeder pipe - does that need slow bends too?...is there any relationship (distance wise) between the two pipes I need to know of?

corgiman said:yes the feed pipe does
if you use 90's on it you will raise the risk of it blocking up
thats plumbing for you
that should be within 150mm of each other[/quote]
The feed pipe is tees into the vent pipe about half-way up it...where do I measure the 150mm from?

Possibly...but i remember someone mentioning that it was done where head height was an issue....as it is in a single storey it may be because of that
As a side issue...I'm putting my pump next to the boiler... its going to have plenty of elbows on the run as its going to come down off the top (boiler connections)and then back up and into loft...are there any issues with that?
Many thanks guys.

DIA i think he done this to death on a previous thread
Just remembered...one last one for tonight ...do I need a bypass valve even though i already have a bathroom rad serving as one (straight off the return and flow from the boiler) if so, where should be situated on the system?
