To gap or not to gap?
In the process of replacing my kitchen faucet config and have been shopping for a Waterstone set up. I notice all their suites have air gaps. It's been many years since I had an air gap and really did not know what they were. Having now (somewhat!) educated myself here by reading threads, I wonder if it is advisable to have one.
Our state code apparently does not require it, and I've never had an issue with our "high loop" under the sink. We had first a Fridgidare DW I think, and now Bosch, but will be changing that out soon for possibly a Kitchenaid. I have only 4 holes drilled in my granite, and want to use them judiciously. Should I reserve one for an air gap to be safe, and be a good citizen? And does the necessity for an air gap vary with DW brands, or is it all a matter of the high loop under the sink?
No RO system in use. Still, I would hate to special order faucet configs and DWs that were incompatible. Many thanks.
