What fittings?

[Redhotferrari]

Hi Guys,

Please see pictures below

View media item 5327
The lead above the joint goes up to bath tap, which I want to remove and replace with copper. But how! I assume I unscrew the nut and discard fo the old lead, but what fitting do I use on the remaining thread, to then connect copper/plastic to?

Look forward to your replies.

Many thanks

what is the bottom pipe if the top is lead ?

 

[Redhotferrari]

Sorry, forgot that bit! Bottom bit appears to be old galvanised

 

[seco services]

can you not use a fi to compression

 

[Redhotferrari]

Thanks Seco, was thinking that, just wanted to be sure! Assume the thread on the old galv will be 3/4"?

Will the FI seal OK against the galv?

Once again, thanks for your quick response and help

you won't be touching the galv.
if you remove the nut you'll be screwing the new fitting onto the existing brass fitting.

 

[Redhotferrari]

Ok, remove the brass nut and all lead etc above it. I am then left with the galv and male thread. My concern was that the 'fitting' on the galv looks more part of the galv, not a fitting as such.

If you are telling me a fi with comp will do the job, we are both happy!

Thanks for your thoughts

remove the brass adaptor that goes into the galvo socket (it will come out easier than getting the socket off) then use a male adaptor

ok its hard to tell from the pic if its galv or brass
long as the thread is standard you'll be ok.
have you got a compression nut that you can try on the thread first then if it fits go buy your fi fitting.

Sorry guys, did not notice the smaller 'nut' under the top one!

So assume that the top and bottom 'nut' are part of a male iron, remove that whole fitting, and replace with another male iron?

cheers

you can do it both ways remove and fit new mi or just add a fi

i'm being somewhat pedantic here you might think, but copper/brass & galvanised should not be directly joined together on water pipework.

a dielectric or nylon/plastic fitting should be used to reduce the steel corroding.

then this brings up the question of supplementary bonding i suppose.

House is earthed to latest 17th edition, so no need for supp bonding (so I have been told) although all the pipes in the bathroom are already supp bonded from years ago.
