A loose shower handle is usually the easy one. There’s often a small screw under the cap in the middle, and once it backs out, the handle rocks. If the screw is tight and it still spins, the ridges inside the handle, or on the cartridge stem it grips, are worn smooth, and the handle or cartridge is the fix.
Close to three in ten homes in the City were built before 1960. In the rowhouses of Old Town and Del Ray, and the 1940s and 50s brick houses around them, plenty of tubs still have two or three handles on the wall, with no pressure balancing behind them. Those drip at the stems and washers, and they jump hot when a toilet flushes. We can rebuild them, and we’ll tell you when a new valve is the better spend.
Alexandria’s water is on the hard side for this area. Virginia American Water, which buys it from Fairfax Water, reported 4.6 to 11.2 grains per gallon in 2025, and Fairfax Water reported 3.0 to 10.8 on the county side. That leaves scale on cartridges and heads. A handle that gets stiff, then starts dripping, is often a cartridge that scale has worn down.
More than half of the City’s owner homes are condos, and in the West End towers, a shower often can’t be shut off by itself. Swapping a cartridge can mean the building engineer closes a valve for a whole stack, so we schedule with management first. On the Mount Vernon side, in Fort Hunt, Groveton and Hybla Valley, many split-levels and ramblers have the tub against a closet or a panel, which makes a full valve change a lot easier.
