<p>An electronically-controlled faucet has a hot-cold water mixing valve disposed in a cup-shaped housing with an open end of the housing accessible from the top side of a deck to which the housing is mounted. Water supply and discharge lines are connectable to the housing. A spacer between the closed end of the housing and the mixing valve supports check valves that prevent cross flow and reverse flow. The spacer also supports a filter screen located downstream of the mixing valve. The filter screen has a wetted area greater than the cross sectional area of the water supply lines and ports. A removable cap covers the housing. All of the mixing valve, check valve and filter components are accessible from above the deck without disconnecting any of the water lines.</p> |
