Identify Valve Type: Determine if you have a single-control, dual-control, or pressure-balance valve
Before adjusting your American Standard shower valve for hotter water, it's crucial to identify the type of valve you have. American Standard offers various valve types, each with distinct mechanisms and adjustment processes. The three primary types are single-control valves, dual-control valves, and pressure-balance valves. Understanding which one you have will guide you in making the correct adjustments safely and effectively.
Single-control valves are the simplest type, typically featuring one handle that controls both water temperature and flow. These valves are often found in older shower systems. To identify a single-control valve, look for a single lever or knob that moves in a circular or linear motion. When adjusting for hotter water, you’ll need to focus on the valve’s temperature limit stop, which is usually located inside the valve cartridge. Accessing this requires removing the handle and possibly the cartridge itself, depending on the model.
Dual-control valves feature two separate handles: one for hot water and one for cold water. These valves allow for precise control of both temperature and volume. To determine if you have a dual-control valve, check for two distinct handles or knobs, often labeled "hot" and "cold." Adjusting for hotter water in this system involves ensuring the hot water handle is fully open and checking for any obstructions or issues with the hot water supply line.
Pressure-balance valves are designed to maintain a consistent water temperature, even when other fixtures in the house are in use. These valves typically have a single handle that controls temperature and a separate dial or lever for volume. To identify a pressure-balance valve, look for a handle that moves up and down for volume and rotates for temperature control. Adjusting for hotter water in this system often involves recalibrating the temperature limit stop, which may require removing the handle and adjusting the internal mechanism.
To confirm your valve type, inspect the shower handle and surrounding trim. American Standard often labels or marks their valves with model numbers or type indicators. If visual inspection isn’t enough, consult your shower’s manual or contact American Standard customer support with your model information. Proper identification ensures you follow the correct steps for adjusting your valve, avoiding potential damage or safety risks. Once you’ve identified your valve type, you can proceed with the appropriate adjustment method to achieve hotter water.
