FAQs

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

A dual-flush toilet is designed with two distinct flush volumes: a low-volume "half" flush for liquid waste (normally 0.6–0.9 gallons per flush) and a higher-volume "full" flush for solid waste (usually 1.1–1.28 gallons per flush). A split push-button or a two-position lever lets you choose the appropriate flush each time, reducing the overall water used without sacrificing performance. The bowl and trapway are engineered to clear waste effectively with these lower volumes, and the valve seals tighter than on older toilets to prevent leaks between flushes.

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

Switching from a pre-1994 3.5 gpf toilet to a modern dual-flush model can save a family of four up to 13,000 gallons of water every year—roughly a 50–60 % reduction in toilet water use. Based on Hillsboro’s 2024 residential water rate (about $5.00 per 1,000 gallons for supply and sewer), that’s an annual savings of around $65–$70 on your utility bill. Even if you already have a 1.6 gpf toilet, the dual-flush upgrade can still trim another 15–20 % off your toilet water consumption.

Will a dual-flush toilet fit my existing bathroom plumbing?

In most Hillsboro homes, yes. Standard dual-flush toilets use the same 12-inch rough-in distance and ⅜-inch supply line connection found in the majority of bathrooms. During our free on-site estimate we verify three things: 1) rough-in distance, 2) clearance around the bowl for the new design (elongated vs. round front), and 3) floor flange condition. If your flange is damaged or your rough-in is 10" or 14", we can recommend compatible models or install an offset flange adapter so you don’t have to remodel the entire space.

Are there rebates or incentives for installing a dual-flush toilet in Hillsboro?

Yes. The City of Hillsboro’s Water Smart plumbing program and Clean Water Services currently offer a $50 bill credit for replacing an older 1.6 gpf or greater toilet with a WaterSense-certified dual-flush model. In addition, Energy Trust of Oregon lists qualifying high-efficiency toilets and may provide an extra $25 rebate when purchased through participating retailers. We handle all paperwork and provide the manufacturer’s WaterSense documentation so you receive any rebates you qualify for.

What does a typical dual-flush toilet replacement cost and how long does it take?

For most homeowners the total project falls between $450 and $750. That includes the WaterSense-certified toilet ($250–$450 for a quality mid-range unit), a new wax or rubber seal, upgraded stainless-steel supply line, haul-away of the old fixture, and professional labor ($180–$250 depending on complexity). We schedule a two-hour installation window, and the toilet is usually back in service the same day. Larger projects—such as moving the flange or repairing a damaged subfloor—can add time and cost, but we provide a detailed written estimate before any work begins.

What maintenance does a dual-flush toilet require after installation?

Dual-flush toilets are engineered for longevity, but a few simple practices keep them working efficiently: 1) Avoid drop-in chlorine bleach tablets, which degrade rubber seals. 2) Clean the push buttons or lever periodically to remove mineral buildup and ensure smooth operation. 3) If you notice the toilet "ghost flushing," it may need a new flush-valve seal—an inexpensive part we can replace in minutes. 4) Once a year, inspect the supply hose for wear. We offer an optional annual plumbing tune-up that includes these checks and a complimentary water-efficiency test for your entire home.
