Sloan R-1002-A Regal Urinal Diaphragm Rebuild Kit - For use

The Verdict

The fix for a running urinal that actually works — if you buy the right one.

Let’s be blunt: a urinal that won’t stop running is wasting water and driving your water bill up. Before you call a plumber, know this — most Regal urinal flush valve issues trace back to one worn diaphragm. The Sloan R-1002-A rebuild kit is the OEM replacement that fixes it. But is it worth the premium over generics? Here’s the honest breakdown.

What you actually get

This kit includes the critical wear parts for a Sloan Regal urinal flush valve: the rubber diaphragm, the refill tube, and the saddle gasket. The diaphragm is the heart of the valve — when it hardens or warps, you get that continuous trickle or inconsistent flushes. The kit does not include the handle, cap, or vacuum breaker, so if those are cracked, you’ll need to order them separately. As shown in the product image, the components are genuine Sloan-branded, not generic aftermarket parts.

Real-world performance

The install is straightforward if you’ve done basic plumbing. Shut off the water, remove the valve cap, swap the old diaphragm out, replace the refill tube and saddle gasket, and reassemble. Budget 10–15 minutes. The diaphragm seats properly on the first try — no wrestling with a part that’s slightly too thick or thin. One buyer noted, “Fixed the leak immediately. The generic ones I tried before never sealed right.” That’s the core advantage: precision tolerances.

What buyers consistently praise

The 4.6-star rating across 229 reviews isn’t an accident. Recurring themes in feedback:

• Exact fit — “Perfect match for the original. No modifications needed.”
• Stops the leak — “My water bill dropped $40 the next month.”
• Durability — “Installed in a commercial restroom six months ago, still working perfectly.”

Where it falls short

Two honest caveats. First, the price point is steeper than generic kits — you’re paying for the Sloan name and guaranteed fit. If you’re fixing a single residential toilet, that premium might sting. Second, the kit doesn’t include the valve body cap or handle. If your existing hardware is old and corroded, you might end up making two trips to the hardware store. Some reviewers also noted the refill tube can be slightly stiff on first installation, though it softens with heat and water exposure.

Who should buy this

• Homeowners with a Sloan Regal urinal who want a one-and-done fix without calling a plumber
• Property managers maintaining multiple restrooms — the OEM reliability justifies the cost over cheap knockoffs
• DIYers comfortable with basic plumbing who want genuine parts

Skip it if you’re on a tight budget and your valve is ancient with multiple worn components — you may need more than this kit, and a full valve replacement might be smarter.

FAQ

Q: Will this fit all Sloan Regal urinals? A: It fits standard Regal urinal flush valves, but check your model number. If you have a Royal or a different series, this won’t match.

Q: Do I need special tools? A: Just an adjustable wrench and possibly a screwdriver for the cap. No specialized plumbing tools required.

Q: How often should I replace the diaphragm? A: In normal residential use, every 3–5 years. In high-traffic commercial restrooms, expect to replace it annually.

The Verdict: 4.6/5

Buy it if you want a reliable, OEM-grade fix for a running Sloan Regal urinal and value a part that installs right the first time.

Skip it if you’re fixing a one-off issue on a valve with heavy corrosion elsewhere, or if budget is your only concern — generic kits work, but they’re a gamble on fit and longevity.

For most people, the Sloan R-1002-A is the right call. It’s more expensive than the generic alternative, but the water savings and the fact that you won’t be redoing this job in three months make it worth every penny.
