Shower and tub valve repair in Sacramento, CA
When a shower swings from hot to cold, the valve is telling you something.
Temperature swings, drips and stiff handles almost always trace to a worn cartridge or a pressure-balance spool. We replace cartridges in place when parts exist, and replace the valve body from behind the wall or through the trim when they do not.
What shower valve repair covers
Modern shower valves include a pressure-balancing or thermostatic part that keeps the temperature steady when someone flushes a toilet. When that part scales up or wears, the shower turns scalding or cold without warning. Older two- and three-handle valves drip as their stems and seats wear.
Most valves can be repaired from the front with a new cartridge and trim. When the valve body itself is failing, or parts are discontinued, we replace the valve. If there is an access panel or a closet behind the shower, the tile usually stays untouched.

Shower Valve Repair in Sacramento: what we see locally
We see a lot of original 1960s and 1970s two-handle tub valves in Citrus Heights, Carmichael and the Pocket area. Parts still exist for many of them, so a rebuild can keep the original tile intact.
Most shower valves are repaired from the front, with the trim off and the tile left alone.
In homes on harder water, cartridges scale faster. If your shower valve needs attention every few years, the water itself is part of the problem.
What you can safely do before we arrive
- Shut off the water to the shower, or the main.
- Note the brand on the handle or trim plate if visible.
- Check whether there is an access panel behind the shower wall.
Shower Valve Repair questions
Will you need to break my shower tile?
Most repairs are done from the front with the trim removed. Full valve replacements are done from behind the wall when there is access, so tile is rarely touched.
Why does my shower get hot when someone flushes?
The pressure-balance part in your valve is worn or scaled and is not adjusting fast enough. Replacing the cartridge usually fixes it.
Can you change my tub to a walk-in shower?
Yes, as part of a remodel. See bathroom remodel plumbing.
