Water filter under sink:
If you are going to be installing an under sink water filter and a bench mounted filter tap place another cold female wingback next to the dishwasher wingback. To be a separate feed for the filter unit. The placement of this extra wingback will simplify the fit off later.
If this wingback is not provided you will have to provide a ½-inch (15 mm) brass tee and a
small inline ball fix valve to go to the filter after branching it in to the cold line feeding the kitchen sink tap.
