In Rex, most shower valve problems are worn cartridges or seals in single-lever valves, which a plumber replaces through the trim. Because Rex is unincorporated, larger jobs like valve replacement go through Clayton County's permit office. Call the number on this page to be connected with a local plumber in Rex.

What's usually behind a Rex shower?
Census survey figures for Rex put the median year built at 1995, with about 20% of homes from before 1980. Most showers therefore have single-lever valves, many pressure-balancing, whose cartridges wear out after years of use. The older homes near Historic Rex Village may have two-handle valves that need stems and seats instead.
Who handles water and permits for Rex?
Clayton County Water Authority provides water and sewer throughout the county, including Rex. CCWA's service line runs from the main to the meter; the line from the meter to the house is the customer's. CCWA also installs and annually tests backflow devices at customer connections with its own certified staff.
Rex gave up its town charter in 1922, so Clayton County's Community Development building permits office in Jonesboro issues plumbing permits here.
Is a valve replacement worth it over a repair?
Only when needed. If the valve body is sound and parts are available, a cartridge or rebuild is the sensible fix. Replacement makes sense for a cracked body, a leak at a joint inside the wall or an older valve with no parts left. If you're replacing anyway, a pressure-balancing model adds protection against sudden temperature swings.
When the plumber arrives, they'll shut off the water, remove the handle and trim plate and pull the cartridge or stems. Most visits end with a new cartridge or rebuild kit. If the valve body needs replacing, the plumber will look for access from behind the shower before opening tile, and can explain whether Clayton County requires a permit for the work. Plan for the water to be off for part of the visit. Rex's homes span several decades, from the historic village to 1990s subdivisions, so the valve behind one shower can be very different from the one next door. A brand name or a photo of the trim helps the plumber bring the right parts. If the valve is from a maker whose parts are no longer sold, replacement becomes the practical route.
A local note
CCWA has also completed a water service line material inventory with a public lookup portal. That covers the utility-side line, not interior plumbing, but it's useful if you're planning broader work on an older Rex home.
