Sloan Flushmate BU-100505-K Upper Supply Kit for all series

Fit flushmate 501a. I cut the upper hose clamp with my dremel and heated the hose with hair dryer to release it. Everything worked perfectly. Original factory part

Muy buen producto

Perfect match and installation on my toilet. This part did NOT fix the problem, but that wasn't the fault of the part. If you're having trouble, check your tank itself for pinhole leaks. With some soapy water, I found a tiny, tiny bubbling leak near the top of the tank that was slowly leaking out all the pressurized air. So over a couple days, the toilet would stop flushing properly until I bled it down and started again. So the problem may be something other than these toilet parts. In my case, I dried everything and patched the area with JBWeld.

My parents had a plumber say they would likely have to order parts that would be a lot. Well, I couldn't believe that as it had just been working fine but was moved for some drywall work and put back. I had reset the tank before by shutting the incoming water off, flushing, etc and was able to get it going, so had some exposure to it. They said it was leaking, so I looked and it appeared to come from this supply valve. Apparently, this has a small rubber duckbill [Flushmate Duckbill Valve (Air inducer) - I may have been able to just replace it directly, too.] that may degrade over time. I ordered and replaced this easily and it worked fine. It did make a whistling noise for a bit, but pushing this assembly a little off line stopped it and it hasn't come back. The toilet is working fine and it has been several months. Next time, may just need to replace the duckbill. It looks to be the real wear item here.

Took 5 minutes to install and works great no leaks. If your hose has a compression clamp I suggest loosening and cutting it off, the hose in mine was short enough and cutting it like the instructions suggested would have made it too short.
