Hilton and Starwood will soon allow guests to unlock their rooms via a smartphone app. Starwood, owner of the Sheraton, Westin and W hotel chains, has upgraded 30,000 room locks in nearly 150 hotels so they can be unlocked with the new app. Hilton is planning to enable guests to do the same thing in its 600,000 rooms next year. That hotel chain will begin by piloting a smartphone app at 10 U.S. properties in early 2015. Also, in early 2015, Hilton's HHonors mobile room key app will be enabled at all U.S. properties of Conrad Hotels and Resorts.

Question: The inspector who checked the home we're selling reported that the dishwasher needs an air-gap device on the drain line. The problem is that we have no place to install an air gap because the hole on the back rim of the sink is being used for the water purifier. Instead of an air gap, our handyman has installed a check valve in the dishwasher drain hose below the sink, but the home inspector says this does not comply with code. The handyman says air gaps and check valves are equally effective and that even a high-loop drain line can be used to prevent back-siphonage.
