FAQs
What is a dual-flush toilet and how does it save water in Monterey?
A dual-flush toilet is equipped with two buttons or levers: a low-volume flush (about 0.8-1.0 gpf) for liquid waste and a full-volume flush (1.28 gpf or less) for solid waste. Compared with older 3.5-gpf toilets common in pre-1990 homes, a dual-flush model can cut indoor toilet water use by 50–70 %. In a drought-sensitive region like Monterey County, that translates to thousands of gallons saved per household each year and lower monthly water bills.
Are dual-flush toilets compliant with California and Monterey Peninsula water regulations?
Yes. All models we sell and install are WaterSense-certified and meet or exceed the California Energy Commission’s maximum of 1.28 gpf. They also satisfy Monterey Peninsula Water Management District (MPWMD) retrofit requirements, which mandate high-efficiency fixtures for home sales, remodels, and certain commercial permits. Choosing a compliant model ensures you avoid fines, inspection delays, and extra retrofit work later on.
Will a dual-flush toilet fit my existing plumbing and bathroom layout?
In most cases, yes. Modern dual-flush bowls use the same 12-inch rough-in and standard 2-inch trapway found on the majority of U.S. toilets. If your home has an older 10-inch or 14-inch rough-in, compact and offset models are available. Our technicians verify rough-in distance, flange height, water-supply placement, and clearance around the bowl during the on-site estimate to ensure the replacement will fit without costly floor or wall modifications.
What is involved in upgrading or replacing my current toilet with a dual-flush model?
1) On-site assessment: We confirm measurements, check flange condition, and review any code or ADA requirements. 2) Model selection: We help you choose a style, height, and color, explaining flush performance ratings and warranty coverage. 3) Removal: Your existing toilet is drained, unbolted, and hauled away for eco-friendly recycling. 4) Installation: We install a new wax or rubber seal, stainless-steel bolts, and supply line, then level and secure the bowl and tank. 5) Testing & tutorial: We verify leak-free operation and demonstrate both flush modes. Typical labor time is 1.5–2 hours, and your bathroom remains usable the same day.
How much does a dual-flush toilet installation cost in Monterey, and are rebates available?
Pricing varies by brand and features, but most homeowners spend $525–$750 total, which includes the fixture ($250–$450), installation labor ($175–$225), and permit/haul-away fees ($50–$75). MPWMD currently offers a $100–$125 rebate per qualifying high-efficiency toilet, and California’s Save Our Water program periodically adds bonus incentives. We handle the paperwork and deduct the rebate from your final invoice when eligibility is confirmed.
How do I maintain and troubleshoot a dual-flush toilet after installation?
Routine care is simple: (a) Clean the bowl with non-abrasive cleaners; (b) avoid in-tank tablets that can degrade seals; (c) inspect the dual-flush valve seal annually and replace it if it shows wear—no tools required. If you experience a weak flush, first check that the water-supply stop is fully open; next, verify that the adjustable flush valve hasn’t shifted from the factory setting. For continuous running, shut off the supply, remove the canister seal, rinse debris, and reinstall. Our installations include a 2-year workmanship warranty, and most manufacturers provide 5–10-year parts coverage.
