Toilet Flush Valve

I built my own house and put in 3 Toto Aquia one piece toilets and 1 Toto Aquia two piece toilet. They look great, but I’ve been really disappointed in how they function right from the beginning. They have been prone to leaking and running constantly and just a huge disappointment considering how much I paid for them. I called Toto to complain about 2 of the 4 toilets, and they sent me free of charge, 2 new original TOTO THU338N, as replacements. They worked and resolved the leaking problem. It’s been almost 10 years, but a few months ago, that same leaking problem started, so I tried replacing the rubber gaskets and parts but nothing seemed to work so I bought this off brand product and replaced the whole assembly with it. It fits and works like the original Yes you can try replacing the gasket and other rubber parts that wear out over time that cost $10+ when you include the shipping, but for $25 for the whole assembly, with all the rubber parts, it’s really the better way to go. Save yourself the hassle and just buy and replace the whole assembly from the beginning. I’m going to buy a couple more just to have, who knows what they will cost in the future.

We have a Toto toilet that was leaking. This fit perfectly and fixed the problem. Seal was tight, easy to install for a novice. Seems to be as durable as the original old one.

It works perfectly fine. The plumber had to cut the length of the inlet section but its good.

I received it super fast and it worked perfectly in my Toto toilet

I have an older dual flush water ridge toilet from Costco and water ridge does not make the replacement flush valve assembly or even just the flush valve anymore. This was perfect . I did not need to replace the whole assembly just the dual flush valve that is blue/yellow. You turn the flush valve to lock into position on the existing assembly. I don’t know how long this will last as I just did this today . I wouldn’t buy dual flush toilets anymore . I prefer to have a standard toilet , just makes it easier to find simple parts at the local hardware stores.

Works great in the older Wateridge toilet from Costco.

At first, I thought this unit wouldn’t work on my Toto one piece dual flush. It seemed to be made for a lid where the flush buttons were stacked front to back. I needed side by side. But upon further inspection I realized the top part of the unit can be locked down by rotating it in either direction. One does side by side, the other way does front to back. Works like a charm. Easy install.

It was had to find good info on the web, but I took a chance and it paid off, this fit my Swiss Madison 1 piece toilet perfectly and solved my running toilet problem. at this price I should buy another and store it for future replacement
