It was not a Chinese knockoff. Rather original Tethford part. I found it rather hard to install. Had to disassemble 3 times, but finally got it right. Instructions were lame.

Worked as described. Fixed my problem. I was ready to replace the toilet, but the seals went out on both of my toilets at the same time. Great buy.

Water valve not shutting all the way off. Slowly adding water to toilet bowl. Easy repair with quality parts. Instructions could have been better but plenty of videos on you tube.

My Thetford Toilet continued to run after flushing. Found out that the little valve rubber thingy (technical term) with the spring in it had hardened up after four years of use. While it wasn't necessary to take the whole toilet apart I did to give it a good cleaning. The only thing I would add is to make sure that when you install the valve gasket, you slide it up the valve tube until it stops at the ridge at the top (see picture). DO NOT SLIDE IT UP ON TO THE RIDGE!All works well again.

Noticed a few drops of water after flushing near the pedal of the toilet. This kit fixed the problem. Installation is fairly simple. In my installation there was just enough room to replace the parts while leaving the toilet installed. Only requires basic tools.Product is made in USA.

Parts looked identical to the ones replaced. The O-ring fit and sealed exactly like it should contrary to some of the other reviews.
