Bathroom Plumbing Services in the Tri-Valley
Over 20 Years of Trusted Residential Plumbing
A bathroom that does not drain properly or a shower valve that scalds one minute and freezes the next makes your morning miserable. Barnett Plumbing and Water Heaters repairs and replaces showers, tubs, faucets, drains, and fixtures for homes across Pleasanton, Dublin, Livermore, San Ramon, Danville, and the Tri-Valley.
Shower and Tub Repair
A dripping showerhead or a tub faucet that will not fully shut off usually points to a worn cartridge, a corroded valve body, or failed seals inside the wall.
We open the valve, identify the failed component, and repair it with manufacturer-spec parts. If the valve body itself is too far gone, we replace the entire assembly and patch the access point.
For tub drains that barely move, we clear the blockage and inspect the overflow and drain shoe for corrosion.
Tub drain assemblies in older Tri-Valley homes often need full replacement once they start leaking at the shoe gasket.
Bathroom Drain Repair and Clearing
Slow bathroom drains are usually caused by hair, soap buildup, or a partial blockage in the branch line. We clear the clog and inspect the P-trap and drain fittings for leaks. If the drain assembly is cracked or the pop-up mechanism has failed, we replace the parts and test for proper flow before leaving.
Recurring drain problems sometimes signal a deeper issue in the main branch line. If clearing the drain does not hold, we recommend a camera inspection to see what is happening further down the pipe.
Bathroom Plumbing Problem? We Can Help.
Bathroom Fixture Replacement
Replacing a bathroom faucet, showerhead, or tub spout is straightforward when the supply lines and valves behind the wall are in good shape. When they are not, the project gets more involved. We assess the condition of the existing plumbing before quoting, so there are no surprises once the work starts.
We install all major fixture brands and handle everything from single-hole lavatory faucets to multi-function shower systems with diverter valves.
Toilet Work
We handle toilet repairs and replacements too. Running toilets, weak flushes, wax ring failures, and complete toilet replacements are all part of what we do. For detailed information about toilet-specific services, visit our toilet repair page.
Bathroom Remodel Plumbing
Moving a shower drain, adding a second vanity sink, or converting a tub to a walk-in shower all require plumbing modifications behind the walls and under the floor. We rough in new supply and drain lines, set the fixtures, and pressure-test the entire system. We coordinate with your general contractor or work directly with you on smaller projects.
Frequently Asked Questions
How do I know if my shower valve needs replacing?
If adjusting the handle does not control the temperature properly, or if you see water seeping from behind the handle plate, the valve cartridge or body is likely failing. Our plumbers open the valve, inspect the internals, and let you know whether a cartridge swap or a full valve replacement is the right call.
Can you convert my bathtub to a walk-in shower?
Yes. Tub-to-shower conversions require relocating the drain, adding new supply lines, and sometimes modifying the subfloor. We handle all the plumbing work and coordinate with your tile contractor or general contractor on the finish side.
Why does my bathroom drain keep clogging?
Recurring clogs in bathroom drains are usually caused by hair and soap residue buildup in the P-trap or branch line. If the problem comes back frequently after clearing, there may be a partial blockage or pipe damage further down the line. A camera inspection can pinpoint the cause.
What does a bathroom faucet replacement cost?
The cost depends on the faucet type and the condition of the supply lines and valves behind the wall. We quote a fixed rate on-site after inspecting the existing plumbing, so you know the full cost before we start.
Do you work on older homes with galvanized pipes?
We do. Many Tri-Valley homes built before the 1970s still have galvanized supply lines that corrode over time. We can replace sections or repipe with copper or PEX as part of a fixture replacement or remodel project.
