DQ water system change

Dear All,
I have a question about which could be the necessary steps of revalidation for a change in a PW distribution system. The system is subjected to layout change consist in sample piont valve and relative tubes. Can I validate my new system just with IOQ and PQ or it could be better to consider also a new DQ step?
Kind regards

Hi, I would definitely recommend a DQ. Challenge the updated design before it is done in real life. This might save you some serious issues (not to mention costs) should the updated design prove to be faulty.

Many thanks
