I'm installing a dishwasher and was told I need an airgap between the
diswasher output and the garbage disposal connection. I've seen these
at the local home centers yet I never see these in any of the kitchens
shown in remodeling magazines or on any of the remodeling shows on TV.
The counter tops usually show the facet, maybe a soap dispenser, etc,
but I have never seen an airgap on the fancy kitchen remodels.
Is there another type of airgap that is hidden under the counter top?
or is there a special one way valve that can be subsituted for the above
