Pressure and water check
Incoming pressure and water quality are checked, because reverse osmosis needs adequate pressure and a suitable feed to perform.
Plumbing Service · Hermitage, TN
Reverse osmosis gives one tap in the home truly filtered drinking water, removing the dissolved solids, chlorine taste, and odours that a pitcher filter only partly addresses. It needs correct pressure, a drain connection, and filter changes on schedule to work, and we install and maintain it as a system, not as a box under the sink.
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
Reverse osmosis gives one tap in the home truly filtered drinking water, removing the dissolved solids, chlorine taste, and odours that a pitcher filter only partly addresses. It needs correct pressure, a drain connection, and filter changes on schedule to work, and we install and maintain it as a system, not as a box under the sink.
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.
Incoming pressure and water quality are checked, because reverse osmosis needs adequate pressure and a suitable feed to perform.
The unit, storage tank, drinking-water faucet, and drain connection are installed neatly, with shut-offs and access for filter changes.
Prefilters, membrane, and postfilter change intervals are left in writing, with the first change date noted.
The system is leak-checked, flushed to the maker's instructions, and taste-tested at the tap before handover.
Hermitage homes
Reverse osmosis is a point-of-use system: it serves one drinking-water tap, usually in the kitchen, rather than the whole house. That distinction matters in Hermitage homes, where whole-house hardness and scale need a softener or entry filter, while drinking-water taste needs filtration at the tap. We explain which problem each system solves before quoting, so a homeowner does not buy a whole-house solution for a one-tap problem, or the reverse.
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 |
|---|---|---|
| Taste and chlorine concern, city water | Carbon plus reverse osmosis at one tap | Install |
| Whole-house taste concern | Point-of-entry filtration, not RO alone | Filter the entry |
| RO unit slow, filters overdue | Filter service, not replacement, usually | Service |
| RO unit leaking from fittings | Fittings or housing fault | Repair |

Questions
It removes a very high proportion of dissolved solids, chlorine taste, and many contaminants, but no system removes everything. We explain what the system is rated for and what it is not, in plain language, before installation.
Prefilters and postfilters need changing on schedule, commonly every 6 to 12 months, and the membrane less often. We leave the schedule in writing and note the first change date.
The drinking-water tap flows from a storage tank, so normal use is fine. Heavy continuous use can outrun the tank and membrane, which is why sizing and pressure are checked at installation.
Most kitchens can take one, provided there is space under the sink, a drain connection, and adequate pressure. We check access and pressure before quoting.
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.
