Common property vs own plumbing changes

Hi All

I am hoping to get some advice on the following issue I am facing with my unit.

We renovated two bathrooms and relocated a laundry from upstairs to downstairs.

The strata is now asking us to have the bylaw amended so that we are responsible for any future plumbing issues that may occur in both my unit and the one beneath, for example a burst pipe that leads to flooding.

When we did the renovation, our architect was under the impression that as we were not creating any new ingress or egress to the property, but merely extended existing plumbing services that there was no need for a bylaw amendment, but rather that all we needed was a building certificate to demonstrate that the work was professionally done and comes with a seven year builders warranty.

Can anyone please advise if we are indeed required to have the bylaw amended, that in all likelihood will have an effect on our being covered by the strata home insurance policy?

If we are, can we insist that there is a seven year limit on the bylaw based on std builders warranty as it seems unfair if there is no end date to the bylaw for both us and future owners?

Thanking you in advance
