Whether you are a DIY enthusiast looking to install it yourself or a homeowner comparing options for a renovation, this review provides the data and insights you need to make an informed decision. Let’s dive into why this Gerber combination is making waves in the American plumbing market.

What Makes the Gerber Allerton 1.28 GPF Stand Out?

When searching for a new toilet, the sheer number of options can be paralyzing. The Gerber Allerton series distinguishes itself through a blend of reliability and efficiency. But what exactly makes the Gerber Plumbing Allerton 1.28Gpf Bowl W He-28-580 Tank White a superior choice?

The Power of 1.28 GPF Technology

The “1.28 GPF” stands for 1.28 Gallons Per Flush. This is a significant upgrade from older standard toilets that used 3.5 or even 1.6 gallons per flush.

• Water Conservation: By using only 1.28 gallons, you reduce water consumption by approximately 20% compared to standard 1.6 GPF models.
• Cost Savings: For an average family of four, this can save thousands of gallons of water annually, directly lowering your monthly water bill.
• Eco-Friendly: Reducing water usage contributes to broader environmental conservation efforts, a key factor for many modern homeowners.

According to the Environmental Protection Agency (EPA), high-efficiency toilets (HETs) like the Gerber Allerton are crucial for sustainable home infrastructure. While we often look to general knowledge sources like Wikipedia for the history of sanitation, the practical application of HETs in modern US homes is where the real value lies.

The HE-28-580 Tank Advantage

The tank model HE-28-580 is specifically engineered to work in harmony with the Allerton bowl. It is not just a container for water; it is a precision instrument designed to deliver the right amount of hydraulic pressure.

• Optimized Flush Valve: The tank features a large flush valve that releases water quickly, creating a strong siphon action in the bowl.
• Adjustable Water Level: Homeowners can adjust the water level within the tank to fine-tune performance, ensuring you never use more water than necessary.
• Durability: Gerber is known for using high-quality vitreous china and durable internal components that resist wear and tear over time.

Design and Aesthetics: Does It Fit Your Bathroom?

A toilet is not just a functional item; it is a visible part of your bathroom’s design. The Gerber Plumbing Allerton 1.28Gpf Bowl W He-28-580 Tank White offers a timeless look that complements various interior styles.

Classic Contours with Modern Efficiency

The Allerton bowl features a traditional elongated shape. This design choice is intentional:

1. Comfort: Elongated bowls provide more seating area, which is generally considered more comfortable for adults than round-front bowls.
2. Hygiene: The extended shape helps keep the user further from the bowl’s edge, promoting better hygiene.
3. Visual Appeal: The smooth, white vitreous china finish is easy to clean and reflects light, making smaller bathrooms appear larger and cleaner.

Dimensions and Space Requirements

Before purchasing, it is critical to measure your existing space. The Gerber Allerton is designed to fit standard rough-in dimensions.

Note: Always verify your rough-in distance (the distance from the wall to the center of the floor bolts) before ordering. Most US homes have a 12-inch rough-in, but older homes may vary.

Installation Guide: Step-by-Step

Installing the Gerber Plumbing Allerton 1.28Gpf Bowl W He-28-580 Tank White is a manageable DIY project for those with basic handyman skills. However, if you are uncomfortable working with plumbing, hiring a licensed plumber is always recommended.

Tools You Will Need

• Adjustable wrench
• Screwdriver (Phillips and Flathead)
• Putty knife
• New wax ring (or wax-free gasket)
• Level
• Bucket and sponge

Step 1: Remove the Old Toilet

1. Turn off the water supply at the shut-off valve.
2. Flush the toilet to drain most of the water. Use a sponge to remove remaining water from the tank and bowl.
3. Disconnect the water supply line.
4. Unscrew the caps at the base of the toilet and remove the nuts from the closet bolts.
5. Carefully lift the old toilet and place it on an old towel or cardboard.
6. Scrape away the old wax ring from the flange and clean the area thoroughly.

Step 2: Prepare the Flange

Inspect the closet flange for damage. If it is cracked or broken, repair it before proceeding. Install a new wax ring on the flange (or on the bottom of the new toilet outlet, depending on the type of ring used).

Step 3: Install the New Bowl

1. Carefully lower the Gerber Allerton bowl onto the flange, aligning the bolt holes with the closet bolts.
2. Press down firmly to compress the wax ring.
3. Place the washers and nuts on the bolts. Tighten them alternately and evenly. Do not overtighten, as this can crack the porcelain.
4. Check the level of the bowl. If it rocks, use plastic shims to stabilize it, then trim the shims and caulk around the base (leaving the back open to detect leaks).

Step 4: Attach the HE-28-580 Tank

1. Insert the tank-to-bowl gasket and bolts into the bottom of the HE-28-580 tank.
2. Lower the tank onto the bowl, aligning the bolts with the holes in the bowl.
3. From inside the tank, secure the bolts with washers and nuts. Tighten evenly to ensure a watertight seal.
4. Connect the fill valve to the water supply line.

Step 5: Final Adjustments

1. Turn the water supply back on.
2. Let the tank fill. Adjust the water level if necessary using the adjustment screw on the fill valve.
3. Flush the toilet several times to check for leaks at the base and the tank connection.
4. Install your chosen toilet seat.

Performance Analysis: Pros and Cons

To help you decide if the Gerber Plumbing Allerton 1.28Gpf Bowl W He-28-580 Tank White is right for you, here is a balanced look at its strengths and weaknesses.

Advantages

• High Efficiency: Uses only 1.28 gallons per flush, saving water and money.
• Reliable Flush: Gerber’s gravity-fed system is known for consistent performance without the noise of pressure-assisted models.
• Easy to Clean: The smooth glaze on the vitreous china resists staining and buildup.
• Standard Parts: Replacement parts for Gerber toilets are widely available in hardware stores across the US.
• Aesthetic Versatility: The white finish and classic design fit almost any bathroom decor.

Disadvantages

• Seat Not Included: Most Gerber toilets do not come with a seat, requiring an additional purchase.
• Gravity-Feed Limitations: While effective, gravity-fed systems may not handle heavy waste as aggressively as pressure-assisted toilets (though they are much quieter).
• Installation Weight: Porcelain toilets are heavy; two people are recommended for safe installation.

Frequently Asked Questions (FAQ)

1. Is the Gerber Allerton 1.28 GPF clog-resistant?

Yes, the Gerber Allerton is designed with a fully glazed trapway. This smooth surface reduces friction, allowing waste to pass through more easily and reducing the likelihood of clogs. The 1.28 GPF volume is sufficient for most household needs when paired with the efficient HE-28-580 tank.

2. Can I adjust the water level in the HE-28-580 tank?

Absolutely. The fill valve in the HE-28-580 tank is adjustable. You can raise or lower the water level to customize the flush power. However, keep in mind that lowering it too much may compromise flushing performance.

3. Does this toilet come with a seat?

Typically, no. Gerber sells the toilet bowl and tank as a unit, but the seat is usually sold separately. This allows you to choose a seat with features you prefer, such as slow-close hinges or ergonomic designs.

4. How does 1.28 GPF compare to 1.6 GPF?

A 1.28 GPF toilet uses 20% less water per flush than a 1.6 GPF model. Over a year, this can save a family of four approximately 3,000 to 4,000 gallons of water. Modern engineering ensures that 1.28 GPF toilets perform just as well as their higher-consumption counterparts.

5. Is professional installation required?

While professional installation is recommended for those unfamiliar with plumbing, many homeowners successfully install Gerber toilets themselves. The process is straightforward if you follow the manufacturer’s instructions and take proper safety precautions.

6. Where can I buy replacement parts for the HE-28-580 tank?

Replacement parts, such as fill valves, flappers, and flush valves, are widely available at major home improvement retailers like Home Depot, Lowe’s, and Amazon. You can also contact Gerber customer support for specific part numbers.
