Hi, I just joined this site and of

You need a certficate of impianto - and its unlikely that the plumber will sign off on work he hasnt done.  If you dont have the certificate you cant sell the house.   But, there is nothing to stop you doing it yourself. 

Thanks modicasa! But is there nothing at all you can do yourself in the way of plumbing without a 'certificazione impianto'?

You could do everything yourself, but it would cause you problems when you later want to sell or rent out the property. The certificazione also protects you should there ever be any serious problems. Many have found them selves with problems because they don't use professionals or take professioanl advice.Italians included!

I understand what you are saying, but do you need a certificate for every little thing to be able to sell or rent? I guess you don't need a certificate to change the filter in the faucet, but is that the limit?

No just do it and if you ever sell sort it then... I'm sure that's what Italians do....

I probably will do just that. I just thought there might be a clear set of rules for d.i.y. like they have it in, for instance, England, Germany and Scandinavia.

Well, strictly its the impianto that is certfied - if you change a toilet then you arent touching the impianto - so its a flexible interpretation!   i would quite happily do everything that isnt tubing/boilers/sewage without a 'professional'

Sorry, I should have added I wouldn't touch any plumbing work, but that's just because I'm useless at it!

Thanks modicasa! That is also how I interpret 'impianto'. And it's also how it's interpreted in the 'rulebooks' of the northern european countries.
