The people who owned my house before me had the water tank(s) in the attic
disconnected and a combi boiler installed. We now have three pipes capped
halfway up the wall in the 2nd bedroom, which for obvious reasons I want to
remove ! Two of these are obviously hot and cold (15mm) water pipes, one of
which I've removed. The 3rd is a pretty wide pipe (well a lot bigger than
22mm anyway). Does anyone have any idea what it might be ? Would it be gas
? (I'm guessing the boiler used to be in this room)

Also I've noticed the pipe I've not removed is still connected to the mains
(guess how I know that!), is it wise to cap it off under the floorboards, or
would it be better to get it removed from where it joins the main (used?)
piping in the house ?

Thanks

Too big for gas - could it have been the feed/return to
the cylinder?

Not sure what you mean ?

The hot water cylinder.

Sorry my knowledge on these matters is pretty limited, I didn't understand
what you ment by feed/return.

Whenever I've seen big fat pipes, they have usually been connections
between the radiators in an old C/H system.

Actually here the rad pipes are 10mm

Ah - it might have been the big pipe coming from the
boiler that takes hot water to the cylinder, or the
big pipe returning to the boiler from the cylinder.
If the boiler or cylinder have been replaced/moved,
there might be some left-overs.

In many older systems where gravity fed primaries were used, it was
common to use 28mm pipe between the boiler and the hot water cylinder.

It's most likely the 28mm pipe coming from the old tank.

thanks for all the ideas
