Product Overview

The HydroStop replaces flimsy rubber flappers with a sturdy tower, it is engineered to eliminate the most common toilet problems. Unlike the angled, floating close of a flapper, the HydroStop drops vertically and solidly onto the flush valve opening to create a better seal and eliminate the possibility of leaks. The EPA estimates that 20% of all toilets leak up to 200 Gal. of water a day, mostly because of faulty flappers. While ordinary flappers are connected to the handle with a thin chain that is subject to improper tension tangles and breakage, the HydroStop features a durable stainless steel cable that is stronger, lasts longer and is less likely to break. The HydroStop also features patented S.T.O.P. Technology (Safe Toilet Overflow Protection) that helps prevent bowl overflows. In the event of a clog, lifting up on the handle immediately drops the HydroStop tower and closes the flush valve so that water does not continue to drain from the tank into the bowl.

  • Handle activates spring loaded S.T.O.P. technology to immediately prevent overflows
  • Eliminates the guesswork about buying the right type and size of flapper
  • Permafit silicone seal is chemical resistant and will not warp
  • Drop-in installation with no tools or tank removal needed
  • Light touch handle allows for an easier flush
  • Fits standard 2″ to 2-1/2″ flush valves

Broken Knob of flapperless toilet

The knob is broken, Can I get replacement knob?
Asked by: sant
Same here. Specifically, the plastic rod that connects the handle to the flush actuator. Seems to be a design or manufacturing flaw. Stronger part (better able to withstand repetitive torque of operation over months of use) would be desirable. Called DANCO support number as described in other post. They are sending me a replacement handle. Otherwise, the system works well.

Yes since the lever is connected with flexible rubber instead of metal rod

Asked by: karen
Check and confirm the seal on the tank is clean and not damaged. If it is damaged it will have to be replaced prior to installation. Pour some water confirm the seal is tight. If it leaks reset before proceeding.

I've installed two of them. Easy and quick to install -- do read the instructions though, makes it easier (get it seated on the pipe and then push that wedge in, etc.). First one I installed was after repeated attempts to get different flappers to seal, and none of them would seat properly. That's when I first used the HydroStop, and it's great. Seals the tank nicely and easily, and it also flushes with a nice smooth and easy pressure on the handle. Two years and it's still working great. I'd give this six stars if I could -- it's that much of a problem solver! Very highly recommend it to anyone!

This replacement flapper was very easy to install, however, if you have an older tank and the rubber part that goes to the bowl may be worn, then you need to replace that. You will also need to seat the replacement unit in different positions to make sure there is no slow leak. The lever works well and we like the feature that you can turn the lever upward to immediately stop the flushing. We had the unit installed for about 2 months now and it is still working great. We had an older version that uses the push button instead of lever, and that unit lasted a good 3 or 4 years before we had to replace it.

Pretty easy to install and works well.... until the cable between the handle and device gets sticky. Then there is nothing you can do but replace the whole gizmo. Might as well get something different and skip this item. One year service doesn't make sense in my book.

I was frustrated trying to get the right adjustment on the traditional flapper and chain assembly. Decided to replace it with this system. It was easy to install and worked perfectly the first time. Installation time 10 minutes with no leaks.

I installed four of these on two different make toilets. The volume of water per flush is adjustable and the units seem to work better on toilets with deeper tanks. On the toilets with shallower tanks, even at the maximum flush setting, the handle has to be held down until enough water enters the bowl to start the flush action. Otherwise, not enough water is released from the tank to complete the flush action. These replacements have stopped toilets running continuously due to flappers hung up on chains.

I was a little skeptical at first, but after reading the reviews on it, decided to give it a try. The unit was pretty easy to install. I did it twice only because I still had a leak, which ended up being the fill/overflow tube (it had a crack). I installed it a couple of months ago and it is still operating well. I'm hoping it lasts a long time. One feature that I really like about is that it can stop the bowl from continuing to fill by returning the handle to its original position.
