hello. i am replacing my kitchen cabinets and need some advice on the plumbing aspect of it. the drainage and the dishwasher shouldn’t be a problem. my question is how to disconnect the sink and leave the new pipes esailly accessible for the new cabinets. the existing set-up is two copper pipes that come through the floor and then through the base of the cabinet on up to the sink. can i cut these pipes just above the base and fit some sort of flexible tubing fitting onto them?? and suggestions would be appreciated.
