FAQs

What is dual-flush technology, and how does it work?

A dual-flush toilet is designed with two flushing options: a low-volume button or lever (usually 0.8–1.1 gallons per flush) for liquid waste and a full-volume button (typically 1.28–1.6 gallons per flush) for solid waste. The mechanism uses a specially engineered valve and bowl geometry to clear waste efficiently at both settings, giving you control over water use every time you flush.

How much water and money can I save by upgrading to a dual-flush toilet in Philadelphia?

Most pre-1994 toilets use 3.5–7 gallons per flush (gpf). Switching to a WaterSense-certified dual-flush model can reduce usage to an average of about 1.1 gpf. For a household of four flushing 15–20 times per day, that equates to roughly 10,000–13,000 gallons saved each year. At Philadelphia Water Department’s current average rate (around $0.007 per gallon for water and sewer combined), that’s $70–$90 in annual savings—plus lower demand on the city’s treatment infrastructure.

Do I need a permit in Philadelphia to replace my existing toilet with a dual-flush model?

Under Philadelphia’s Department of Licenses & Inspections (L&I) rules, a like-for-like toilet replacement that doesn’t alter the plumbing layout is considered "ordinary repair" and does NOT require a permit. However, if your project involves relocating the fixture or changing drain sizes, a plumbing permit and work by a licensed Philadelphia Master Plumber are required. Our team handles all permitting if your upgrade goes beyond a simple swap.

Are there rebates or incentives for installing high-efficiency dual-flush toilets in Philadelphia?

Yes. The Philadelphia Water Department (PWD) periodically partners with the Energy-Star and WaterSense programs to offer rebates—typically $50–$100 per qualifying toilet—when you install a WaterSense-labeled dual-flush unit purchased through participating retailers or installed by a registered plumber. Funds are limited and offered on a first-come, first-served basis, so we always verify current availability and help you file the paperwork at the time of scheduling.

Can a dual-flush toilet be installed in any bathroom, or are there compatibility issues?

In most cases, a dual-flush toilet fits the existing 12-inch rough-in (the distance from wall to waste outlet) found in Philadelphia homes. Where the rough-in is 10" or 14", or where cast-iron waste lines are older than 50 years, an adapter flange or minor drain adjustment may be needed. During our free on-site assessment, we inspect the flange height, shut-off valve condition, and supply line to ensure compatibility and provide an upfront quote for any ancillary work.

How long does a typical dual-flush toilet replacement take, and what should I expect during the service visit?

A straightforward replacement takes about 1.5–2 hours. Our licensed plumber will: 1) protect the work area with drop cloths, 2) shut off water and drain the old toilet, 3) remove and recycle the unit under PWD guidelines, 4) inspect/replace the wax ring, closet bolts, and supply line, 5) set and level the new dual-flush toilet, 6) test both flush modes for leaks and performance, and 7) haul away debris. You can use the toilet immediately; we just advise avoiding harsh cleaners for 24 hours while seals fully seat.
