Review: Effective and Quickly Installed - My original Geberit toilet was purchased as I remodeled a small space. It was a rare solution to the small geometry of bathroom space. It worked great for 20 years and then filled too slowly to be practical. I ordered the part and found a senior plumber who installed it quickly. It is obviously a newer design for that part. It works smoothly with the original unit.
Review: Easy fix for dripping Geberit toilet - Quick fix for my leaky Geberit wall toilet. Had a slow constant leak which was immediately stopped with this seal kit. Even an amateur diy-er can replace this part with a screwdriver and 20 minutes. Geberit’s design is very intuitive. I thought it would be intimidating becuase I’ve never fixed an in-wall toilet, but YouTube has excellent videos. Just as easy to fix as a standard toilet.

## Questions & Answers

**Q: Where is the gasket that is failing on the Toto fill valve? I have pulled out my in wall fill valve but am not sure which part I need to replace.**
A: Thanks for your question, I was confused as well.  There is another gasket  on the TOTO fill valve at the water inlet side (the one visible when you remove the yellow compression clip).  It is NOT this gasket.  What you do is to gently unsnap the top blue cover on the fill valve, unsnap the levers, then give the white plastic disc a turn with pliers.  Go easy.  The black rubber diaphragm on the TOTO pulls out and you can discard it and replace with the silicone one from the Geberit assembly.  The plastic pieces on the Geberit are of no use.  Unless the thing is cracked, the TOTO assembly will work perfectly!

### ⭐⭐⭐⭐⭐ Easy fix for dripping Geberit toilet
*by R***N on August 18, 2020*

Quick fix for my leaky Geberit wall toilet. Had a slow constant leak which was immediately stopped with this seal kit. Even an amateur diy-er can replace this part with a screwdriver and 20 minutes. Geberit’s design is very intuitive. I thought it would be intimidating becuase I’ve never fixed an in-wall toilet, but YouTube has excellent videos. Just as easy to fix as a standard toilet.

### ⭐⭐⭐⭐⭐ I used the white gasket included to fix my Toto in-wall toilet/Toto THU134
*by T***E on March 7, 2024*

My 8 year old Toto in-wall toilet uses Toto THU134 water fill valve ($130). The black gasket located inside the THU134 had a big tear and the symptom was constant water running or leaking in the tank and bowl. I decided to purchase this $13 Geberit because it included a very similar gasket, but white in color. I exchanged the gaskets in my THU134 and it works so far on Day 1! It was not an easy job, but there are a couple of YouTube videos that will show how to remove the parts inside the wall unit. Saved myself $120!
