Toilet Replacement & Upgrade Services

Repair vs. Replacement: When to Upgrade
How do you know if you need a simple toilet repair or a total replacement? Trust the experienced team at Jim Dandy to provide an honest, accurate assessment.
We recommend a Toilet Replacement if:
High Water Consumption: Your toilet was manufactured before 1994 and uses more than 1.6 gallons per flush (GPF). Upgrading to a modern, high-efficiency model will quickly pay for itself in water savings.
Frequent Clogs: If you consistently need a plunger or professional drain cleaning, a narrow or defective trapway in your fixture may be the cause.
Cracked Porcelain: A crack in the toilet bowl or tank compromises the structural integrity and seal, posing a major risk of leakage and is not safely repairable.
Foundation Issues: The flange or drain components under the toilet are badly worn, often discovered when the toilet is rocking or leaking at the base.
If you are unsure whether to repair or replace your toilet, call Jim Dandy today. We provide upfront diagnostics to help you make the most cost-effective decision for your home.

Comfort-Height Toilets: These fixtures feature a slightly taller seat height, which makes sitting down and standing up easier. They are an excellent upgrade for seniors and those with limited mobility.
Dual-Flush Technology: These efficient toilets allow users to select a low-volume flush for liquid waste or a full flush for solids, optimizing water use with every flush.
Bidet Toilets and Seats: We offer professional installation of modern fixtures that include integrated bidet functions, providing an advanced upgrade in personal hygiene.

Frequently Asked Questions
Why is my toilet running constantly, and how do I fix it?
A constantly running toilet is one of the most common residential plumbing issues, and it's a significant water waster. The problem is usually caused by a faulty component in the toilet tank, which prevents the flush cycle from sealing completely.
The solution depends on which component is failing:
Faulty Flapper/Flush Valve Seal: This rubber or plastic seal lifts when you flush and then drops to seal the water in the tank. If the flapper is old, warped, or covered in mineral deposits, it allows water to slowly leak into the bowl. This causes the fill valve to kick on frequently to replace the lost water.
Fix: Replace the flapper with a new one that matches your toilet model. This is often an inexpensive and easy DIY repair.
Improperly Adjusted Fill Valve: The fill valve controls the water level. If the water level is set too high, water will spill down the overflow tube, causing the tank to constantly try to refill.
Fix: Adjust the water level screw or clip on the fill valve so the water line sits about one inch below the top of the overflow tube.
Worn Fill Valve (Ballcock): If the fill valve itself is old, it may fail to shut off the water completely, causing a continuous refill or a slight trickle.
Fix: The entire fill valve mechanism needs to be replaced.
What should I do if my toilet is clogged and a plunger isn't working?
If a standard plunger (which should have a flange, or collar, to create a tight seal) fails to clear a clog, you need to step up to a mechanical tool to physically break up or retrieve the blockage.
Use a Toilet Auger (Closet Auger): This tool, specifically designed for toilets, is a flexible cable with a coiled end protected by a rubber sleeve. You insert it into the toilet trapway (the S-bend at the bottom) and crank the handle to manually clear the blockage without scratching the porcelain. If you are unable to do this yourself it is likely you will need to contact a plumber to clear the issue.
Clear the Main Drain (If Necessary): If water backs up into other drains (like the shower or sink) when you flush, the clog is likely past the toilet and in the main drain line or sewer line. At this point, the problem is beyond an in-home fix. Avoid using chemical drain cleaners, as they rarely work on large sewer clogs and can damage your pipes or pose a health hazard to you or your plumber. You will need to call a plumbing or sewer professional to use professional-grade drain snakes or hydro-jetting equipment to clear the blockage deep within the system.
Are "flushable" wipes really safe to flush?
No, despite what the packaging says, "flushable" wipes are generally not safe to flush and pose a significant risk to residential plumbing and municipal sewer systems.
Standard toilet paper is designed to break down almost instantly upon contact with water, rapidly dissolving into tiny fibers. "Flushable" wipes, however, are typically made of materials like polyester or rayon and are often held together with resins. While they may clear your immediate toilet bowl, they do not disintegrate in the same way.
These wipes will travel through your drainpipe and can snag on small imperfections, grease, or roots inside the pipe. Over time, they accumulate into large, dense masses often called "ragging" or "fatbergs," which are the leading cause of expensive sewer line clogs and municipal sewer backups.
The rule of thumb for safe plumbing is: Flush only human waste and standard toilet paper. Everything else, including wipes, cotton swabs, and dental floss, should go into a trash bin.
What does "low-flow" or "high-efficiency" mean?
The terms "low-flow" and "high-efficiency" refer to modern toilets designed to save water compared to older models, without sacrificing performance.
Federal Standard (1.6 GPF): Before 1994, toilets typically used between 3.5 and 7 gallons per flush (GPF). Federal law mandated that all new toilets manufactured use no more than 1.6 GPF.
High-Efficiency Toilet (HET) / Low-Flow (1.28 GPF): This is the current best practice for water conservation. An HET uses 1.28 GPF or less, which is at least 20% less water than the federal standard. Many are certified under the EPA's WaterSense program, which guarantees both water savings and effective flushing performance.
The Benefit: By upgrading an old 3.5 GPF toilet to a new low-flow 1.28 GPF model, the average household can save thousands of gallons of water per year, leading to a significant reduction in monthly water utility bills.
