Does Replacing Old Toilets Really Save Water and Money? (A Guide to Water Savings and a $100 Toilet Rebate!)

Wondering if replacing old toilets really saves water and money? If you’re a Renton homeowner, the answer is a resounding yes—and the City of Renton’s toilet rebate program makes it even easier to upgrade. At Trusted Plumbing & Heating, we specialize in helping you replace aging toilets with new, water-saving toilets that bring real cost savings and environmental benefits.

Why Replacing Old Toilets Is Smart for Water and Your Wallet

Older toilets—especially those manufactured before 2004—use much more water per flush than modern high-efficiency toilets. A standard older toilet can use over 3.5 gallons of water every time you flush, adding up to thousands of gallons of wasted water and higher utility bills each year. By replacing your old toilet with a low-flow toilet or WaterSense toilet, you significantly reduce water usage and save money month after month.

Benefits of Replacing Old Toilets:

• Save Water: Modern efficiency toilets use as little as 1.28 gallons per flush.
• Save Money: Reduced water usage means lower water bills.
• Improve Bathroom Performance: New toilets flush better and are more reliable.
• Protect the Environment: Less water wastage supports local water conservation efforts and helps Renton meet its water savings goals.

What Is the City of Renton Toilet Rebate Program?

To make replacing old toilets even more appealing, Renton’s toilet rebate program offers a $100 rebate on the purchase and installation of eligible high-efficiency toilets. Residents can claim this toilet replacement rebate when replacing qualifying older toilets with approved models.

How to Qualify for the $100 Toilet Rebate:

• Check Your Toilet’s Age: Toilets installed before 2004 are often eligible.
• Replace with a High-Efficiency Toilet: Choose a WaterSense toilet or another approved low-flow option.
• Save Your Receipt: Hang on to your purchase and installation receipts.
• Apply for the Rebate: Submit your application online to claim your toilet replacement rebate.

At Trusted Plumbing & Heating, our experts can help you select the best water saving toilets for your bathroom and expertly handle the installation.

How Much Water and Money Can You Save?

By replacing an old, high-flow toilet with a modern low-flow toilet, your household can save thousands of gallons of water annually. That adds up to real cost savings and helps reduce the strain on Renton’s water supply.

• Old Toilet Water Usage: 3.5–7 gallons per flush
• High-Efficiency Toilets: 1.28 gallons per flush (or less)
• Potential Water Savings: Up to 13,000 gallons per year for a family of four

That’s a lot of water, a lot of money, and a big win for conservation.

When Should You Replace Your Toilet?

If you notice any of these signs, it’s time to consider toilet replacement:

• Your toilet is more than 20 years old
• Repeated leaks or constant running water
• Needing to flush multiple times
• Cracks or damage in the toilet

Replacing old toilets isn’t just about saving water—it’s about improving the comfort and reliability of your bathroom, too.
