By the turn of the 20th century, compression valves that required several turns to reach maximum water flow were being replaced by newer models that required no more than a quarter turn. This exerts much less torque on the compression gasket, further reducing wear and extending the life of the gasket.

All commercial faucet manufacturers specializing in heavy-duty faucets for restaurants, hotels and medical facilities design their heavy-duty faucets around very durable right-angle rotary compression valves as standard water control technology. Although direct descendants of the original Guest & Chrimes, these valves are modern incarnations with durable synthetic seat gaskets and detachable seats. Some, however, have remained unchanged for the better part of a century. For example, the venerable Quaturn® compression valve used in faucets manufactured by the Chicago Faucet Company has been in continuous use for more than a century and shows no signs of disappearing anytime soon.

If you delay replacing the gasket, the seat may be scratched or damaged, and polishing the back of the seat to its original smoothness may require the services of a plumber, or at least a DIY-ER with a polished and precise touch. Gasketless valves revolutionize the piping landscape, making it possible to mix single-handle taps. Before the Moen valve, all faucets were double faucets. The hot and cold ends are operated separately. Use moen cylinder valve, only one handle can control hot and cold. Today, 40 percent of all faucets sold in North America are single-handle, and in kitchens, that number jumps to more than 60 percent.
