We would rather not mar up our new counter top with the standard dishwasher drain "air gap". We have heard there is a code compliant back-flow prevention device for this purpose that can be mounted under the countertop.
However none of the plumbing supply stores we have contacted so far know of such a device. Nor have I been able to find one by doing a web search.
Does anyone one on this forum know where such a device can be purchased? Any brands or models?
Tod, I've talked to a few companies who work for me as plumbing subcontractors and have even called some of their suppliers all to no avail.Two suppliers informed me that back flow preventers wouldn't work due to the initial high dicharge pressure and the food particles in the water.Scott
The airgap I installed fits in the spare hole of the Elkay stainless sink. Some people use that hole for other things (such as lotion dispenser or spray nozzle). Does your sink have such a hole?
The new solid surface counter top has two holes: One for the regular faucet and one for the filtered water faucet. The under mount sink has no supply side holes.
We could drill a new hole in the counter top for the air gap, but would like to keep the clean, uncluttered look if possible.
