FAQs
How much water can I save by installing water-saving toilets, faucets, and showerheads?
The EPA estimates that WaterSense-labeled toilets use up to 60 % less water than older 3.5–7 gpf models, saving roughly 13,000 gallons per household each year. Low-flow showerheads cut usage from the standard 2.5 gpm to as little as 1.5 gpm, and WaterSense faucets drop flow from 2.2 gpm to 1.0–1.5 gpm. When all fixtures are upgraded, the typical Charleston home can reduce indoor water consumption by 20–30 %, which translates to hundreds of dollars in annual utility savings.
Will a low-flow fixture make my water pressure feel weaker?
Modern high-efficiency fixtures are engineered to maintain a satisfying spray or flush while using less water. Showerheads rely on advanced aeration and pressure-compensating technology to keep the spray forceful. High-efficiency toilets use redesigned bowls, larger trapways, and powerful siphon jet or pressure-assist systems to clear the bowl in one flush. In most cases, homeowners notice little to no difference in performance—only a lower water bill.
What types of water-efficient fixtures can you replace in my Charleston property?
We supply and install WaterSense-certified toilets, urinals, faucets, showerheads, and smart irrigation controllers. For commercial clients we also offer pint-flush urinals, metered faucets, and sensor-activated flush valves. All products meet or exceed South Carolina Plumbing Code requirements, carry manufacturer warranties, and are selected to match your décor, rough-in dimensions, and performance preferences.
Are there rebates or incentives available in the Charleston area for upgrading to water-saving plumbing fixtures?
Yes. Charleston Water System periodically offers bill credits for WaterSense toilet replacements, and Santee Cooper’s Smart Energy program provides rebates for low-flow showerheads and aerators in qualifying homes. Tax incentives for certain high-efficiency commercial fixtures may also apply. We stay up-to-date on local programs and will help you assemble the documentation needed to claim any available rebates.
How long does fixture replacement take and will my water be shut off?
Most residential toilet, faucet, or showerhead swaps can be completed in 1–2 hours each. We shut off only the local supply to the fixture being replaced, so the rest of your home retains water service. For whole-bathroom retrofits, we coordinate the work to minimize downtime and can stage replacements room-by-room to keep at least one bathroom operational.
Are water-saving fixtures worth the investment?
In Charleston, the average combined water and sewer rate is roughly $11 per 1,000 gallons. A household that trims usage by 13,000 gallons saves about $140 a year. With efficient toilets starting around $225 installed and showerheads near $100, most pay for themselves in 1–3 years. Added benefits include reduced strain on septic or municipal systems, compliance with future code changes, and an immediate boost to your home’s resale appeal.
