This something that has always done my head in.
Commercial COCN1.
After a boiler service is a tightness test something that HAS to be done, or can you just leak detector fluid the last connection to the boiler.
Obviously a let by/tightness test is done beforehand, but if you turn off the supply to the boiler then dissconect at the boiler, do I then have to do another tightness test or is LDF ok.
I know people will say you should do one for your own piece of mind, I fully appreciate that, however this is something that I have always wondered about!
