Shower and tub valve repair
Call NowTemperature swings, a dripping showerhead and handles that won't shut off usually come from a worn cartridge inside the shower valve. Most can be replaced from the front; a failed valve body needs access from behind the wall.

First step
Identify the valve
Every shower has a valve inside the wall that mixes hot and cold. Its cartridge wears out, and when it does you get drips, stiff handles or water that suddenly runs scalding when someone flushes.
The plumber identifies the valve brand and model first, so the right cartridge is used and the trim still fits. If the valve body itself is failing, the repair is planned to open the smallest possible area of tile — or work from an access panel on the other side.

Shower & Tub Valve Repair: common questions
Why does my shower keep dripping after I turn it off?
The cartridge or valve seals are worn and no longer seal completely. Replacing the cartridge usually fixes it; turning the handle harder won't.
Why does my shower get hot when someone flushes?
Older valves without pressure balancing can't compensate when cold pressure drops. A pressure-balance or thermostatic valve prevents it.
Why is my shower pressure low?
Mineral buildup in the showerhead, a worn or clogged cartridge in the valve, or a partially closed shutoff are the common causes. If the tub spout has good flow but the shower doesn't, the showerhead or diverter is the problem.
Can a shower valve be replaced without removing tile?
Often the cartridge can be replaced from the front after removing the trim. Replacing the valve body itself needs access, ideally from an adjacent closet or a small tile opening sized to a trim plate.
What is an anti-scald valve?
It's a pressure-balancing or thermostatic shower valve that holds the water temperature steady when pressure changes, such as when a toilet flushes. Most codes require one on new and replaced shower valves.
What is a pressure-balancing valve?
A shower valve that adjusts the hot and cold mix when pressure changes, such as when a toilet flushes, to prevent sudden temperature swings. A failing or missing one causes those swings.
Does replacing a shower valve mean opening the wall?
Often only from the front, through the valve opening or an access panel. Full valve replacement may need a small opening behind the trim or from an adjoining closet.
