Copper central heating manifold replacement

[craige]

has anyone changed a copper central heating manifold

i have a small leak in the main joint of the 28mm pipe where one of the microbore 10mm joins it

i have tried pouring leak fix in the header tank and tried sealing the joint but to no avail

i was thinking of replacing it with a plastic manifold or similar if any is available

do you know if you can replace these

any advice would be appreciated

can you explain how i would repair this with this part

would i cut the main pipe section taking out the leaking joint and push fit this part in ?

on one side of the main pipe one of the connections is sealed off so i dont need that one, i need a connection from underneath the pipe going into the concrete and also the other side of the main pipe i need a connection

posted that part BEFORE the pic was loaded........

if it was my own job i would rip it all out and start again, it looks RAF

 

[craige]

the leak is on the first joint on the pipe underneath going through the concrete floor

if i was going to rip it out what would you recommend

how many rads is this manifold supplying?

Do you need to replace it?

Can you not drain down, undo the compression nut where it is leaking clean it up, butter on some jointing compound and do it back up?

Or is the leak actually on the manifold soldered branch or whatever?

 

[craige]

its on the soldered branch where the connection joins the main pipe

Drain down and re-solder ?

Not from that manifold its not.

As Gigs said drain it and resolder it. Probably need unsweated, cleaned and redone.

These Wednesbury manifolds are notorious for leaking at that joint. Replace as my pal Glasga Gas has stated.

If you 11 rads from that one manifold I'd revamp the system completely!!!
