Mansfield Maverick Two-Piece Elongated 1.6 GPF Heavy-Flush Toilet

Mansfield Maverick: The Heavy-Duty High-Flush Volume Two-Piece

The Mansfield Maverick Two-Piece Elongated 1.6 GPF Heavy-Flush Toilet is Mansfield Plumbing's high-volume flush specification — designed for installations where stronger flush performance is required: older homes with smaller drain pipes, low-slope waste runs, commercial use, or specific user preference for high-volume flushing. Mansfield has been a US plumbing manufacturer since 1929 and is best known among plumbers for robust mechanical construction and reliable trade-grade products. The Maverick at $189-$249 retail is a practical choice where 1.6 GPF flush volume is preferred or required.

Why 1.6 GPF Instead of 1.28 GPF

WaterSense 1.28 GPF is the dominant US toilet standard, but specific scenarios call for higher 1.6 GPF:

• Pre-1992 homes with original 2-inch drain pipes that benefit from higher flow velocity
• Older homes with extended horizontal drain runs to the main stack
• Properties where existing 3.5+ GPF toilets are being replaced and drain pipes were sized for higher flow
• Light commercial installations with higher use intensity
• User preference for stronger flush performance regardless of WaterSense status
• Regions where WaterSense requirements don't apply to existing installations

Mansfield's Trade-Grade Heritage

Mansfield has been making US toilets for 95+ years — the brand is one of the oldest continuously-operating US plumbing manufacturers. Mansfield's positioning is trade-grade reliability with broad plumber familiarity, similar to American Standard or Gerber. The Maverick reflects this heritage with robust mechanical construction and parts availability through plumbing supply houses indefinitely.

Elongated Bowl

Elongated bowl shape (~18.5" length) provides more comfortable seating than round-front alternatives. Standard for most modern bathroom installations where space permits.

1.6 GPF Single-Flush

Mansfield's flush valve assembly is rated for higher use intensity — engineered for residential and light commercial applications with longer service life expectations.

Frequently Asked Questions

• Will this fit my bathroom? Standard 12-inch rough-in fits most US homes built after 1970. Measure from the finished wall (not stud) to the center of the closet flange before ordering. For unusual rough-ins (10" or 14") or non-standard floor depths, verify dimensions against the product spec sheet before ordering.
• How long does installation take? Typical installation runs 1.5-2 hours for an experienced installer. Add 30-60 minutes if the closet flange needs replacement or repair, and 1-2 hours if the existing supply line stop valve needs to be replaced.
• Is the toilet seat included? Some configurations include a soft-close seat; others sell it separately for $20-$60. Check the SKU listing before purchase to confirm.
• How much will this save vs. my existing toilet? At 1.6 GPF, this two-piece toilet uses meaningfully less water than older designs. Replacing a pre-1992 3.5 GPF toilet typically saves $70-$110 per year in water utility costs, depending on local water rates and household flush volume — payback on the toilet purchase price within 2-4 years is realistic for most households.
• What's the realistic service life? Expect 20+ years for the vitreous china (lifetime warranty backs this expectation) under normal residential use. Internal flush components (fill valve, flush valve, flapper) typically need replacement around year 7-10 — these are universal hardware-store parts costing $15-$45 total.
• Can I install this myself? Most experienced DIYers can complete installation in 1-2 hours with basic plumbing tools. Hire a licensed plumber if you're uncomfortable with closet flange work, supply line connections, or if your plumbing is older than 1980s and may need flange replacement.
• What's the return policy if it doesn't work for my space? Most retailers accept unused toilet returns within 30-90 days (Home Depot 90, Amazon 30, specialty plumbing 30). Installed toilets are NOT returnable — measure twice, install once.

Step-by-Step Installation Overview

1. Turn off the water supply at the toilet stop valve (the small valve behind/beside the toilet). Flush the tank to drain residual water, then sponge out any water remaining in the tank and bowl.
2. Disconnect the supply line from the bottom of the tank. Have a small bucket and towel ready for any drips.
3. Remove the old toilet: unscrew the two closet flange bolts at the base, rock the toilet gently side-to-side to break the wax ring seal, and lift it off the flange. Have a second person help with the lift — the bowl alone weighs 50-90 lbs.
4. Clean the closet flange thoroughly. Scrape off old wax residue with a putty knife. If the flange is cracked or below the finished floor surface, replace it before proceeding (flange replacement adds ~$25 in parts and 30-60 minutes of labor).
5. Install new closet flange bolts in the flange slots (most kits include these; verify before starting). Place the new wax ring on top of the flange (or on the bottom of the new bowl, depending on installer preference).
6. Set the new bowl over the flange, aligning the bolts through the bowl mounting holes. Press down firmly with even pressure to seat the wax ring. Don't twist or rock the bowl after seating — that breaks the seal.
7. Tighten the closet flange bolts alternately (a few turns on each side, then back to the other) until the bowl is firmly seated. Don't over-tighten — porcelain cracks from excessive bolt torque.
8. Place the tank-to-bowl gasket on the bowl. Set the tank on the bowl, aligning the mounting holes. Insert the tank bolts from inside the tank and tighten alternately until the tank is snug against the bowl (don't over-tighten).
9. Connect the supply line to the bottom of the tank. Turn on the water supply, let the tank fill, and test the flush. Check all connections for leaks.
10. Install the toilet seat (if not pre-installed) by inserting the seat bolts through the bowl mounting holes and tightening the nuts from underneath.
11. Final leak check: flush several times, run a tissue paper test around the base for any seepage, and verify the toilet sits firmly without rocking.

Tools you'll need: adjustable wrench, channel-lock pliers, putty knife, sponge, small bucket, towels, and a level. If you don't have these, expect to spend $40-$60 at a hardware store on a basic install kit.

10-Year Total Cost of Ownership Estimate

• Initial purchase + installation supplies: typical $15-$30 in wax ring, supply line, and flange bolts on top of the toilet price.
• Plumber labor (if not DIY): $150-$350 for standard floor-mount install, $250-$500 for smart toilet, $1,000-$2,000 for wall-hung.
• Replacement seat at year 6-8: $25-$50 for a Bemis or branded replacement.
• Replacement flush internals at year 7-10: $15-$45 total in parts (fill valve, flapper) — universal Fluidmaster/Korky parts at any hardware store.
• Water utility cost (1.28 GPF average, 5,000 flushes/year): $400-$600 over 10 years depending on local water rates.
• Annual savings vs. replacing a pre-1992 3.5 GPF toilet: $70-$110/year ≈ $1,300-$1,800 over 10 years — frequently exceeding the entire toilet purchase + install cost.

Warranty Registration and Care Best Practices

Register this two-piece toilet with Mansfield Plumbing within 30 days of purchase to ensure warranty coverage — most brands require online registration plus original receipt for any future warranty claim. Save the receipt as a PDF and email it to yourself for cloud backup; physical receipts fade and get lost. Photograph the model number sticker (typically inside the tank or under the tank lid for one-piece designs) as part of your warranty documentation.

Common warranty exclusions across all toilet brands:

• Impact damage from dropped tools or items falling on the bowl/tank lid
• Freeze damage in unheated vacation properties or unheated bathrooms in cold climates
• Installation damage from over-tightened bolts (cracks at the flange mount), uneven floors causing rocking, or missing wax ring seals
• Damage from in-tank cleaning tablets (these chemically degrade rubber flapper seals and stain the porcelain)
• Hard water staining (cosmetic, not structural)
• Cosmetic scratches from abrasive cleaning products (especially on matte finishes)

Routine cleaning best practices: Use standard porcelain bowl cleaners (Lysol, Clorox, Soft Scrub with Bleach) for the bowl interior. Microfiber + mild dish soap for the exterior, lid, and seat. Avoid steel wool, abrasive scrub pads, and powdered scrub cleaners (Comet, Ajax) that scratch the glaze over years of use. For hard water mineral deposits, apply CLR or Lime-Away with a 10-15 minute dwell time, scrub with a bowl brush, then flush — repeat for stubborn buildup. Wipe water spots on the rim and seat hinge promptly to prevent permanent mineral etching, especially on matte black or matte gray finishes where mineral staining shows visibly faster than on glossy white.

If a warranty claim becomes necessary, contact Mansfield Plumbing customer service with: photographs of the defect from multiple angles, the model and serial number, your purchase receipt, and the installation date. Expect 5-10 business days for initial review and 15-30 days for claim resolution if approved.
