Can the Watershed EC550 be adapted to become and under the counter unit?

Your EC550, while it does not come with an under-the-counter adapter, the diverter is “shower” style and shuts itself automatically once the water flow has stopped. (Like the old-fashioned tub/shower diverters – you run the water through the tub faucet, then pull up on a metal tab to divert the water to the shower – the EC550 has “pull-tab” style diverter that works like this – once the water supply is shut off, the diverter closes back again and water goes straight through the tap)
