Leaking central heating pipes

We do remember having an overhead tank in the loft with our conventional boiler.
The chap who installed the boiler said he had flushed the system but hasnt mentioned the brand.
As for the site of leaks-twice it was the elbows from copper pipe raising upto the radiator,twice it was radiator valve itself(?spindle),then there was leak below the lockshield valves.Now we have leak from possibly copper pipe underneath a room which has made the ceiling below damp and stained.

Did you find the Benchmark page? There is a section that asks specifically what chemicals were used.

You may be unlucky with the soldered joints in that they could have been done by an apprentice and not fully soldered.
You could have flux corrosion on the outside of the pipe.

I would say it is unlikely for the OP to admit he/she was told about possible problems of changing from open vented to sealed, don't you think?

I don't think any company would take on this liability, but then you could always lie about having any problems.

The installer might be wary of putting off customers with potential problems with the system. Why lose a job with 'maybes'.

The current economic climate is/has created a particularly nasty workplace.

All my quotes carry disclaimers clearly in writing covering this sort of eventuality.

I would have thought most good tradesmen would do the same.

Well the benchmark page is all empty!!

I wonder also did he use self cleaning flux when doing the installation and if so,did he post flush the system to clear any residue?

That has to be completed at the time of commissioning, it's not optional, and you should not have paid him until it was. Then, apart from any other issues, your boiler currently has no manufacturer's warranty-has your RGI registered it with the manufacturer? Has the manufacturer sent confirmation to you?
Did you check if your RGI was GSR before proceeding with the install?
Make and model of boiler?

Have you checked his Gas safe registration and have you raised your concerns formally in writing?

Im afraid if copper pipe ie soldered joints are leaking in the floor etc thats just bad workmanship by the installer of the original system.You shouldnt realy get any leaks on your copper joints although prehaps a rad or some rad vales weeping is to be expected.

1 thing that can help is pressurising your system properly.Where abouts is your boiler fitted ie 3rd floor up in a 3 story prop? or bottom floor of a 3 storey prop.Wont go into too much detail but 1/2 bar and head of water is the best way to pressurise your system or at least used to be
