Question for Doitall

[avidfan]

Just finished a commercial refit and the site agent asked if I was going to 'chlorinate' the main. What does this involve? Is it necessary?

 

[kevplumb]

yes it is

it involves disinfecting all the drinking water pipes

and the question should be asked

I hope he is OK as I havent seen him since the 28th November.

Its part of the procedure fpr commercial water supplies in habited buildings to treat with chemicals to kill any bacteria.

Anyone taking on this kind of work is expected to be aware of the requirements.

I think its only custom and practice and if it was not included in the specification of the works might be difficult to be insisted on although it would come within the definition of "good workmanship".

Topics like this are better discussed in the CC !

Cheers Kev. How do I carry this out. What kit do I need. Most of the main is in Hep due to the difficult route.

Does this help?

Noramllay depends on quantity and sizing but if they've actually specified it then why not try ringing Hydrochem.

They'll come out do it and issues all the steralisation certs.Then if it takes forever its down to them not you.Its not just the treating its the certifying afterwards.

do it all is perfectly fine i spoke to him in another forum

Depends on what the building is used for, and whether it is requested in the spec.

Any new mains over 50mm has to be chlorinated, and as well as most public buildings.

You really need to get a specialist Company in to do though as it needs to be tested and certificated.

Thanks for all your replies. Main is 28mm and nothing is in the spec. Think I'll keep quiet on the subject and hope for the best.

Flush any new pipework out with mains water, to avoid contaminating the storage water.
