Thank you both,brothers - Shahid & Ibrahim, for excellent suggestions.

Our problem is - in piping walk down audit window, we can't have major changes accepted easily.

Moreover, our core area of specialization is pipe supports and pipe stress - mechanical integrity.

When condensate water hammer breaks pipe support, it is our issue, where the slope maintenance and drip leg location fixing are piping layout concern.

So, what we should do -we can't sometimes!
