Plumbing pro Art Slegers creates an indoor dust storm as he cuts through old tile in a client's Parsippany, N.J., shower. He's wearing goggles, coveralls, gloves, a dust mask and—no joke—a shower cap. His 4-inch angle grinder reveals the guts of the shower supply, a system that remains a mystery to most homeowners despite daily use.­Understanding what goes on back there can help a handy DIYer diagnose a leak, dispatch a vexing clog or—as Slegers is doing—upgrade from an old three-handle system to a modern single-handle valve, which can precisely control temperature without sudden drops in pressure. The replacement is tricky; this is not the time to learn how to sweat copper tubing. But even if you never plan to step into the stall wielding Channellocks and acetylene, it's worth learning how the flow goes.Behind the Stall Walls A Pressure-Balancing Valve ExposedA pressure-balancing valve like Moen's 3570 Moentrol prevents a temperature swing in the shower when someone elsewhere in the house flushes a toilet or starts the dishwasher.

This cutaway shows how internal valve mechanisms maintain consistent water pressure and temperature in turbulent conditions. 1 Check Stops Spring-driven gaskets at the valve inlets prevent high-pressure hot water from crossing the valve into a cold supply line or vice versa. (Hot water is at higher pressure in recirculation systems.) Screws in the stops shut off hot and cold lines at the shower for work on the valve cartridge.2 Pressure-Balancing Spool Hot and cold streams slide a graphite-composite piston in response to fluctuating hot and cold water pressure. In 0.1 seconds, the piston (inside the chrome sleeve) seals or opens inlets to maintain balanced pressure between the two flows, which are still unmixed. Lab tests to monitor internal movement show the piston constantly vibrating back and forth.3 Cartridge Pulling the shower handle slides the cartridge forward, opening two inlets to let hot and cold water enter and converge. Turning the handle opens one inlet as it closes the other, allowing users to adjust the temperature.4 Temperature Limit Stop Screwed into the cartridge's rod, this stop prevents a child from fully opening the valve to a scalding-hot setting.>Shower Power >>>

The Latest News on the Lowest FlowsEPA WaterSense regulations require shower heads to use less than 2 gallons per minute (gpm) to douse a 5 x 3–foot stall, while setting standards for pressure and coverage to ensure a satisfying shower, not a miserly trickle.

Here's how three manufacturers hit the new specifications.Moen → Water rides on spokes like a bike wheel's to reach the perimeter of Moen's 8-inch-diameter Envi shower head, avoiding the dry zones common in early low-flow models.Delta → A fat 0.26-mm droplet, twice the typical low-flow drop diameter, helps water in Delta's H2Okinetic hold its temperature and feel like heavy rainfall.Kohler → Silicone polymers molded into distinct nozzle geometries let users set models like the Purist to deliver 1.75 gpm in a broad spray, a sharp beam or a wide deluge.

Moen that is now part of the Fortune Brands Home & Security company. The Moen subsidiary is headquartered in North Olmsted, Ohio. Moen was originally part of Ravenna Metal Products of Seattle, Washington. In 1956, it became part of Stanadyne, which was in turn acquired by Forstmann-Little & Company in 1988 and then purchased by the consumer-products holding company Fortune Brands. Fortune Brands then spun off its related product lines to form the Fortune Brands Home & Security company on October 3, 2011.

Most Moen kitchen, washbasin, and bathtub/shower faucets are of the single-handle design, and almost all have used the same basic water-controlling cartridge since the 1960s. Known as the Moen 1225, it is a plastic (older versions were brass) cylinder approximately 4 inches long by 3/4 inches in diameter. As the "engine" in most Moen single-handle faucets, it has undergone at least two revisions since its inception though newer versions remain compatible with older faucets. Pulling up the stem of the cartridge opens the water supply; rotating toward the left opens the hot water passages while rotating to the right opens the cold water passages (using the standard North American convention of the hot water control on the left). Later Moen bathtub/shower controls with single handles use a larger cartridge with a pressure balancing mechanism which compensates for sudden pressure changes in either the hot or cold water supply (as caused by a toilet being flushed while someone is showering).
