Install · Water Softener

Reverse osmosis (RO) under-sink install

An RO system needs a cold-water feed, a drain saddle on the sink drain above the trap (away from the disposal), a dedicated faucet (often an air-gap faucet where code requires) and the storage tank. Flush the system per the instructions before drinking.

Install · Water Softener

Water softener install with bypass valve

Install the softener after the main shutoff (and usually before the water heater) with a bypass valve so water can run while the unit is serviced. Run the valve drain to an approved drain with an air gap, run the brine-tank overflow separately by gravity, and never join the two.
