Fluidmaster K-400A-023 Mansfield Toilet Fill Valve and Flush Valve Seal Repair Kit Multicolor

quick install and works great

So far so good. Installed this in my mom’s toilet yesterday and it works great. Super easy to install.

Fit perfect, works perfect with easy to understand instructions. This is the kit to get to rebuild the Mansfield toilet. Just be really meticulous installing the large red gasket as it has to be in the right grove and fully seated.

This item was easy to install in my toilet, I didn’t need a plumber, but I did watch a video on YouTube first and made sure that the part was the correct fit for my commode. The repair took me about an hour, as I had to remove the tank from the back of the toilet. I wasn’t thrilled with all the plastic, but the product works great and my potty is flushing away without any problems.

So I purchased the whole pack instead of just the little rubbery red ring. Faster shipping.Worked for me. Fixed the toilet with minimal casualties.

Every 20 minutes, my Mansfield toilet briefly made the sound it makes when refilling after a flush, which was likely was due to a leaky flapper valve. I procrastinated for a year until it broke even more when it continued to make the refill sound and never stopped, which was likely due to a faulty refill valve. I was forced to shut the water valve to stop water from being wasted and had no choice but to either call a plumber or to roll the dice and try to do it myself. I figured I couldn’t make it any worse, so I bought this item and followed the simple replacement instructions and it wasn’t messy at all. I also purchased the Mansfield 630-0206 universal flapper valve and swapped it out with the old one. I turned the water back on and refilled the tank and gave it a few flushes and turned the height dial for fine tuning of the water level. At first, it started to make that brief refill sound periodically but that soon stopped and it’s been working flawlessly. I even changed the flush lever with the chromed plastic lever included in the box. I had to shorten the internal portion of the lever by cutting it down to fit properly. I didn’t use the larger red rubber washer that was included. Overall, I think ai saved over $350 by not calling the plumber this time.

I did the install myself and I'm almost 80 years young.

Returned it cause the toilet continued to run. Probably a good product if it worked correctly
