All you need for an easy Tank Repair
Where do I start, this is the end all for toilet repair kits. Instructions were amazing detailed and even had steps for other brand toilets as well as the dedicated ports for them if needed. The kit included everything you would need to do the job except for the towel and sponge for cleanup and a level to make sure the tank is set properly. It included the tools to remove and install the parts, even a catch basin for the tank water to drain into. Installation was easy and something anyone could manage using the items in the kit. The tools in the kit are good enough quality you could use them many times if needed. My install was leak proof and I really liked the dial on the bowl filler line outlet. Made it super easy to dial bake the flow rate. Ther outflow was much faster than my old filler and was very surprised at the amount of water it put out. The top task filled fast and was very easy to adjust the items in the tank to get the water at the right level. I have bought several tank repair kits over the last 25 years and never been this happy with a kit.

A Sure Fix
I tried 3 different flappers, but the water continued to disappear from my toilet tank. Finally, I ordered this complete rebuild kit; and it solved the problem. It even included special tools for removing old connections. It also came with enough hardware to do a complete renewal; but I used a couple of extra nuts and washers to secure bolts directly to tank. The instructions were clear and easy to read. Drain the water from your toilet tank and make sure you can see the screwdriver slots across the heads of the thru-bolts. If those bolts are badly rusted or corroded, you might need professional help. Otherwise a complete rebuild is simple enough to be done by the average home owner. When you lift the tank off the bowl, check to see if your toilet used small spacers. They are easily overlooked and lost.

Better than what I could have asked for.
Best flush valve replacement/set I could have asked for. Instructions made it very clear as to what I needed to do resulting in an easy install process. They were clear enough for me to complete the install without hitting any “road blocks” and/or issues; and the set really does have everything you need. The packaging was even designed so that you can use it to catch any water coming from the tank which is genius thinking on their part. The manufacturer will be my go-to moving forward.

Give It a Try- You Coukd
At 60 plus years old, this was my first time trying to change out the valves. It went pretty smoothly. Instructions are clear and easy to follow. I think they should tell you to plan on updating the water supply line when you’re doing this as I couldn’t get my old one to connect properly to the new fill valve and ended up stripping it and having to buy another fill valve plus the water supply line. Do yourself a favor and measure for the water supply line/hose and buy that as well. You can always return if you don’t need it. Also the replacement handle is very cheap and wouldn’t come back up after pushing it down to flush. If you run into the same issue, you may need to purchase a different handle.

Just buy the whole replacement kit.
My toilet kept filling periodically because the flapper was leaking. I bought a couple of different flappers and they didn't seal and the problem continued. My brother said, "Just buy the whole replacement kit"!!! So, I did and this one is great, and its not expensive, and it will work on any toilet.

Leak fixed hands protected
The tools in this kit make all the difference. It's great to have wrenches and whatnot around the house, but when you don't have long man arms, it's difficult to use those tools effectively. The two plastic gadgets covering all toilet parts were a knuckle saver. I wish it had a screwdriver in it, but it's still a pretty great value, and I would highly recommend it.

45 minute install
Took 45 minutes from opening the package, reading instructions and doing the job, pretty good deal in my opinion. This is all plastic including lever and lever arm (except the chain), but no points off because that’s what I paid for. Been in for a day and no leaks and working fine. Also much quieter than my old one with the float arm.

Easy and directions work
First I wanna say I’ve never fixed a toilet in my life. This kit made it easy and the directions provided a step-by-step. I was able to make my toilet last, probably a year or too longer if not more and it only took me an hour to replace.
