Shower Valve Repair & Replacement in Lake Oswego, Oregon
A shower that drips when it's off, won't get hot enough, or has a handle that's hard to control usually has a fixable valve problem — not a reason to remodel the whole bathroom. True Flow Plumbing diagnoses and repairs shower valves throughout Lake Oswego.
Shower Valve Service in Lake Oswego
Lake Oswego's higher-end homes frequently request thermostatic shower valve upgrades — systems that maintain an exact set temperature regardless of flow rate or pressure changes elsewhere in the house. These are standard in luxury shower installations and a meaningful upgrade from basic pressure-balance valves. Mountain Park and Palisades homes also commonly need cartridge replacements in 1970s–1980s single-handle valves that have been in service for 40+ years.
🔧 Cartridge Replacement
The cartridge inside a single-handle shower valve controls water temperature and flow — when it wears out, the shower drips, won't regulate properly, or runs either scalding or cold. We stock common Moen, Delta, and Kohler cartridges.
🚿 Pressure-Balance Valve Repair
Pressure-balance valves prevent scalding when a toilet flushes or washer runs — when the balancing element fails, temperature spikes become unpredictable. We repair and replace pressure-balance valves throughout Lake Oswego.
🌡️ Thermostatic Valve Upgrade
Thermostatic valves hold an exact temperature regardless of pressure changes elsewhere in the house — a meaningful upgrade in homes with multiple bathrooms or frequent pressure variation.
🔩 Three-Handle Conversion
Older Lake Oswego homes often have three-handle setups — separate hot, cold, and diverter valves. We convert these to modern single-handle pressure-balance valves for better control and simpler operation.
🛁 Tub/Shower Diverter
A diverter that doesn't fully redirect water from tub to shower — or leaks back into the tub while the shower is on — is a common repair we handle in Lake Oswego.
🏠 Full Valve Replacement
When a valve body is beyond repair or parts are discontinued, we replace the entire valve — body, cartridge, and trim — and restore full function without a full bathroom remodel.

Frequently Asked Questions
Why does my shower in Lake Oswego not get hot enough?
In most cases, a shower that won't get hot enough has a worn cartridge that's restricting the hot water side, a anti-scald limiter set too conservatively, or a mixing valve that's failing. In older Lake Oswego homes, a partially closed hot water shutoff inside the wall can also restrict temperature. We diagnose before we replace anything.
How long does shower valve repair take in Lake Oswego?
A cartridge replacement takes 45–60 minutes in most cases. A full valve replacement — where we're installing new valve body, trim, and handle — typically takes 2–3 hours depending on wall access and the condition of the existing connections. We'll give you a realistic time estimate before we start.
Should I repair or replace my shower valve in Lake Oswego?
If the valve body itself is in good condition and only the cartridge is worn, repair is the right call — it restores full function for a fraction of the replacement cost. If the valve body is cracked, corroded, or the model is discontinued with no available parts, replacement makes more sense. We'll tell you which situation you're in honestly.
