A couple of days ago I noticed that the kitchen faucet base was doing some shifting when I moved the handle from cold to hot. Tonight the faucet is completely detached from the base. It is a single hole, center mount. I found a plate of some sort and part of a severed washer under the sink. I know the plate anchors the unit but I can't figure out how so I guess I will have to enlist the skills of a plumber. Someone will have to remind me exactly WHY I thought owning my own home would be a good idea. I miss having a landlord!!
