TOTOReplacement Valve Cap Assy THU123

If you have a Toto toilet - and you should - you need this. Even if this cap is just a backup. The Toto toilets are much less likely to clog, with better valves and more flush volume. Ask a plumber sometime which toilet he has in his house. About 9 out of 10 will say they own a Toto.But there is a single-point-of-failure in the Toto fill-valve (the blue or green assembly in the tank, which attaches to the handle). Inside that, when you take the cover off, is this valve cap. It tends to fail before anything else. Not that it fails often, just first. You don't need a plumber, the cost of service call, or the effort to replace the entire fill-valve assembly.Just replace this internal cap when you hear that constant hissing of water. Doesn't cost much, and is not hard to install/replace by yourself. Buy one now and save it for later.

Easy to install after I watched a you tube instruction video, but I was momentarily perplexed as to why I now need an overflow tube when my original cap didn’t require one. I wondered if I had made a mistake somewhere until another reviewer also noticed the difference. Not a big deal, I had a little piece of tubing on hand that works fine. I’m jut happy that I didn’t have to replace the entire valve assembly to fix the hissing issue I had.

I was able to replace old unit with this one in a few minutes- works perfectly and no more annoying water hammering

I had a leaky valve that I thought I could repair by just replacing the rubber seal. That didn’t work. For about the same price I got this whole unit and it works like a charm!

Excellent replacement product for TOTO Drake. Easy install. No instructions but just look at YouTube

The original part was severely deteriorated which resulted in an incomplete shut off of the water filling the tank. This part was the exact fit, easy to replace in minutes, solved the problem and reduced my water usage saving me some money.

The replacement solved the issue of the hissing that was due to the age of the original

I used it for my toilet water fill valve it was an easy swap

Works exactly as it should, replaces worn part- easy to install, found a video on line. Bought a similar generic part in a local store but still made a small hissing. This is the right part.

Product fits as advertised but I realized afterwards that Home Depot also sells it for around $5.

It's a necessary replacement part for a squealing, hissing, dual flush Toto toilet yet a Toto distributor told me I couldn't get one because Toto didn't make them anymore. He sold me the entire fill valve which cost more than double the price of the valve cap and diaphragm. So happy I decided to check Amazon.ca. Saved me some money as I needed 3. This product is a genuine replacement part and is really easy to install. Also, got it the next day with Prime so I was able to make sure it worked and got a quick refund from the distributor and informed him that he could direct his customers to Amazon!!

I was able to install this in less than 5 mins m

Super easy to install. Fixed two noisy toilets perfectly. Took 1 minute to swap it out.
