Gerber 99-770 Flapper
Just what I was looking for
By 
My Gerber Avalanche toilet came with a Gerber 99-770 flapper. After about four years of service, the original flapper started leaking. I tried a Corky 3" universal flapper, but that new one leaked also. So, I looked for an original Gerber flapper and none of the big box stores carry them.
The price at Grigg Industries was the lowest even after including shipping, even lower than at Amazon. When I received the flappers (yes, I ordered five!), I was pleasantly surprised to see that these new ones are a bit larger than the original and completely covers the tank opening. These flappers work extremely well. It almost seems like these have magnetic closures.
You cannot go wrong with these flappers from Grigg. Material quality is top notch, design is perfect (easiest to adjust the chain length, easiest to attach to flushing lever) and the price and the delivery time was awesome. Thank you Grigg Industries for making these available to the public at a very reasonable cost.

Excellent product and service

During my search for a replacement Gerber Toilet Flapper, Grigg Industries stood out as having many positive customer reviews stating this product was high quality and worked as it should and that the company was great to work with. Like many of those customers, I had purchased a replacement elsewhere that did not fit right and continued to leak. This flapper looks exactly like the old flapper Gerber 99-770. It fits tight, has good weight, and has not leaked at all. Shipping was fast and I appreciated the prompt and courteous communication from the supplier. I would definitely purchase from Grigg Industries again.

Do not buy the universal ones! Buy the original :)
By 
Like many other reviewers, we tried several universal flappers and none of them worked. Still leaked. We decided we needed to get the original. We picked Grigg because of the reviews. I was very nervous because I am very Amazon loyal. But all of the reviews were 100% true. I ordered on a Sunday, and it shipped two day shipped Monday morning. Flapper installed quick, and works perfect. We bought several for when our other toilers go south. Also, do NOT use the Clorox tabs. I love them so much, but it is the reason my flapper died after 2 years.

Tank flapper
By 
I made several trips to various stores and had to take back the product every time because the toilet still leaked. I went on line to try to get it locally but to no avail. I ordered and received this within 1 week. This fit perfectly and no more leaks. I couldn't afford to pay a plumber to do this as their minimum fee just to come out is $50. The part and shipping was less than $20 so I saved myself the money. This will save me at least $10 on my water bill. Thanks so much.

Good 3" flapper
By 
The Gerber 99-770 flapper was a perfect match to replace the original flapper (same part number stamp "WDI B4802-1"), and now the toilet no longer leaks into the bowl. The price was exceptional ($5.87 + $7.95 shipping = $13.82), much lower than the Amazon price ($11.49 + shipping). Grigg's shipping cost was the same for either 1 or 4 flappers, so I ordered 4 to have some spares. The previous flapper lasted 4 years before leaking.

Correct part

Needed a part for our water-saver toilet tank. Ordered from
Griggs and received it in a few days! didn't expect it so soon, but we were thankful it came so quick, as the tank was leaking all the time and costing us money, also wasting water. We were not able to obtain the part at our local hardware. I will deffinately order from Griggs when we need another part.

Perfect

I couldn't find this product anywhere, not at Ace, Home Depot, or Lowe's. I ordered it from another site and it never showed up after 2 weeks of me waiting with a broken toilet. I found it on this Griggindustries website and purchased it from them. It showed up extremely fast and worked perfectly! I am very thankful for this website and their quick service!

I needed this part for my toilet that is only a few years old. I was unable to find this part anywhere else. All the big box stores did not carry anything but one brand. Even the plumbing suppliers did not have one. I ordered from Griggs and it was in my mailbox in three days. Great service and reasonable price.

Work great!

These flappers are the perfect fit replacements for the flapper in all the toilets in my home. I've had to replace two, so far, and these were an easy change to make. I ordered enough to have a back-up for each toilet and they were shipped and I received them in just a couple of days.

My original Gerber flapper went bad after many years and I had replaced it with a Korky Universal. I eventually got rid of the Universal flapper as it was intermittently leaking water by. Since I replaced the flapper with the same original Gerber flapper I haven't had any issues.
