Valve cartridge & pressure balancing
Shower cartridges and pressure-balancing valves are replaced and adjusted, so temperature stays steady when other fixtures run.
Plumbing Service · Hermitage, TN
A shower that drips, scalds, or barely trickles is usually a valve problem, and a tub that drains slowly is usually a drain problem. We separate the two, fix the right one, and test temperature and flow at every setting before we leave.
Mon–Fri: 7AM – 7PM · Sat: 8AM – 4PM · 24/7 for emergencies. Burst pipe or flooding? Shut off the main water valve first, then call.

What to look for
A shower that drips, scalds, or barely trickles is usually a valve problem, and a tub that drains slowly is usually a drain problem. We separate the two, fix the right one, and test temperature and flow at every setting before we leave.
If you have one of these symptoms, describe it when you call (615) 436-9486. The symptom, the fixture, and whether water is still running help us prioritise your visit and tell you what to shut off while you wait. If water is flooding, shut off the main valve first – see our emergency plumbing page for the steps.
How we fix it
Every visit follows the same pattern: find the fault, show you what we found, price the options, and only then do the work. No part is replaced on a guess.
Shower cartridges and pressure-balancing valves are replaced and adjusted, so temperature stays steady when other fixtures run.
Showerheads, tub spouts, diverters, and trim are repaired or replaced and sealed against the wall.
Tub drains, overflow gaskets, and P-traps are checked for leaks and blockages, including hair and soap buildup.
The shower is run at full flow and checked below and behind, because a valve that only leaks while running is easy to miss.
Hermitage homes
Many Hermitage bathrooms were built with single-handle shower valves that rely on a cartridge to balance hot and cold. When that cartridge wears out, the shower scalds or goes cold whenever another fixture runs. Replacing the cartridge and setting the temperature limit is a straightforward repair that makes the shower safe for children and older adults, and it is one we do often in older ranch and split-level homes.
Homes across Hermitage and Davidson County vary widely in age and plumbing material, so the same symptom can have different causes in different streets. That is why diagnosis comes first: a slow drain in a newer home and a slow drain in an older home with mature trees in the yard are not the same job, and they should not get the same quote. We explain the cause we found in your home, in plain language, before recommending a repair.
| What we find | What it usually means | Our recommendation |
|---|---|---|
| Drip from showerhead, valve under 10 years | Cartridge failure | Repair |
| Scalding when other fixtures run | Pressure-balancing valve failed or missing | Repair / upgrade |
| Valve body corroded, parts obsolete | Replacement valve needed | Replace valve |
| Tub leaking through the ceiling below | Drain or overflow failure; inspect first | Inspect & repair |

Questions
Your shower valve is not balancing pressure. A pressure-balancing or thermostatic valve holds temperature steady when other fixtures draw water. A worn cartridge is the usual cause.
A drip is usually the valve cartridge, not the showerhead. Replacing the showerhead alone rarely stops it. We test the valve first.
Usually hair and soap buildup in the drain, the overflow, or the trap. We clear it and check flow. If several fixtures drain slowly, the main line may be the cause instead.
Treat it as urgent. Do not use that shower until it is checked, and call us. A valve or drain leak above a ceiling damages drywall and framing quickly.
Call (615) 436-9486 and describe the symptom, the fixture, and whether water is still running. We give you a time window, tell you what to shut off while you wait, diagnose the fault on site, and quote an upfront price before any work begins. Emergencies are answered 24/7.
Still unsure? Call (615) 436-9486 and describe what you are seeing. We would rather answer a question than have a small leak become a large repair.
