flux corrosion inside.of pipe

[Mgrant]

If working on a new build estate and first fixing in copper, if the houses hot and cold water and heating system is fillled for around a year could this cause problems with corrosion from any flux internally on the pipe?

pipework should be flushed and fully drained down when first fixed so no problems should arise when filled and used after 1 year.

This doesnt happen, just flushed when filled cold flush the warm flushed with cleaner and final warm flush

Just the policy were I work?

 

[ShaunCorbs]

boiler warranty gone before you even start then

 

[Mgrant]

No the pipework will be flushed before any water goes through the boiler

 

[plumben]

If the pipe work isn't flushed and left for a year then yes it could suffer from flux corrosion in that time

How would you flush before filling the system?

How would you flush before filling the system?

I'd use hoses connected to an outside tap and to the system and another section of hose back out to a drain if there was not an easy way to dump the water. Then drain off completely using the drain off cocks and finally a wet vac to get the last of it out.
