How to Install Danco Next Duo Flush Conversion Kit and Review

Quick install, saves water, reliable, but a tight fit for smaller tanks. CORRECTION: I misspoke about the green mini-valve that controls the bowl re-fill level at 3:45: down is fully OPEN and up is fully CLOSED. I had it reversed in my explanation. Sorry for the error!

This is the only KZbin channel I subscribe to. Phil is great because he gets right to the point, does a much better job than the manufacturer of pointing out critical details, and doesn't play dumb background music. If multi-million dollar manufacturers could do 70% as well as Phil, Phil would be out of the video business.

Very helpful video. 1 tip for everyone that I missed, is that the nut on the handle is reverse threaded. The longest part of the install was figuring out the reverse thread. Beyond that, it was super easy to install this kit. One thing I would have liked to have seen in this video was how the handle itself worked to select the flush option. Thanks.

This video was very helpful. I could not get the quick flush to come even close to draining the bowl but based on the tips in this video, I tried increasing the height of the fill valve to be a bit higher than the top of my tank, while still fiting under the lid, and that fixed the problem.

[@patrickniemeyer5795]

This is really helpful. I installed the push-style flusher in the two bathrooms in my home about 7 years ago. Recently one has started to "ghost flush" and I can see a slow leak from the tank to the bowl. I disassembled it to try to isolate the leak and inspect the gasket (I'd heard that the material can blister) but the material still appear structurally sound. I don't have the old manuals but I think I can tell from your video that there are some adjustments I should make to the way I create the seal with the cam and adjust the flusher to my overflow tube that may solve my leak. That or I'll just need to install a new one. Thanks for posting!

[@ReviewedByPhil]

You're welcome! Yep, I think I had to make some minor adjustments after it was a few years in service. Eventually a plastic piece broke in the fast-fill valve and I had to replace that part, but at least it was sold separately and I was able to get the same part from a big box store. Good luck with the repair!

This is an excellent video! I watched it several times to familiarize myself with all the aspects of replacing the flush unit. The only thing I noticed was that at 2:53 when you put the flush converter back together you say to screw it in with a clockwise turn, but your video shows a counter-clockwise turn. At 2:18 you mention turning the base clockwise to disassemble the converter so it makes sense to turn it counter-clockwise to put it back together. Phil what do you do for a living? Your presentation and insights are awesome as shown in how you put this video together. I watched several videos from others, but yours is way better and concise.

The larger side of the handle only separates from the smaller side past a certain point. If you press down only on the outer edge of the handle and hold it down, does it still not separate from the smaller section? Try removing the handle and see if the pieces are somehow stuck, glued, or taped together. Mine weren't, but they should separate too when not installed, which could indicate a possible defect if it doesn't.

If I am understanding correctly, the split handle should be able to function with both parts together and also with the larger one functioning separately...but mine is not doing that.

This video made the installation super simple. Thanks a bunch for making it. I couldn’t have done it with just the instructions that came with the product. I do have two issues though - 1) the flush is very weak and 2) I made a pencil mark at the water level as explained in the video, but I can’t seem to lower the water level after the installation. It’s about a inch above the pencil mark. Any help/ideas are highly appreciated.

[@ReviewedByPhil]

To lower the water level in the bowl after a flush, you'll need to adjust the height of the float by turning the thumbscrew shown at 3:19 and lower it. The water level inside the toilet tank is directly correlated to the water level in the bowl after a flush, so lower the height in the tank should lower the amount of water in the bowl correspondingly. Hope this helps!

[@testtesttesttesttest884]

Thanks for the great video Phil. I recently purchased a house and one of the original MSJI Hydrorights was installed. It kept adding more water every 30 minutes and making a loud jet plane sound. I took the unit apart and there is a small bubble on the light blue seal the interfaces of the bottom of the toilet. I'm guessing that's where the leak is coming from as maybe the shape is too irregular to make a complete seal. when there was still water in the tank I tried wiggling the whole plastic cylinder on top of the blue seal every which way but the slow leak back into the bowl continued. Any thoughts?

[@ReviewedByPhil]

Hm, without looking at what the bubble looks like I can't tell if maybe your rubber gasket is deformed or not. If so, perhaps you could exchange it and see if the new unit also has this "bubble." One thing I did notice once when installing one of these units is that if I pushed down too much when installing it, it would create a "wrinkle" in the seal that allowed water to leak down into the bowl. It may seem counter-intuitive, but lifting up on the unit slightly may eliminate the leak by allowing the gasket to meet all the edges of the drain hole for the tank. The unit only needs to be pressed down enough to create a good seal. Pushing it in further, past this point, for "a tighter fit" could actually backfire.

[@db64lifeisback]

So every time I flush the flusher controller adjust and I have to readjust it how can I fix this it’s quite annoying the flusher doesn’t go back into position

[@tfed315]

Loved your video, but I have an old house with 3 large toilet tanks from 1954 that are 21" across, 7" deep and 17" wide. I've installed 2 Danco's alreadyThe water comes up to 4" below the overflow pipe! But everything works. I'm having trouble adjusting the fill valve. it doesn't want to higher or lower.

[@ReviewedByPhil]

To adjust the valve height, grasp upper portion placing your thumb on gray side of the mini-valve and push clockwise ¼ turn. Then slide the upper body to adjust it up or down (see 1:21).

[@mariadanielle7023]

Hi thank you for the fabulous instructions. However I have a little problem with my thin water pipe that connects to the unit so the water leaks. What can I do?

[@ReviewedByPhil]

Hm, usually 2-3 wraps of plumber's Teflon tape on the threads of the connection that is leaking will be sufficient to stop a small leak. Wrap the tape in a clockwise direction (same direction as you turn the connector to tighten it) and be careful no to leave any excess tape hanging off past the last thread. Using too much tape can also cause the threads not to catch and the connection to leak.

[@markwidawer3890]

Excellent video. Much more helpful than the written instructions. I successfully installed one of these and it worked perfectly. I ordered two more and again followed your instructions to install them…but this time the Small Flush uses as much water as a full flush in both toilets. For both, I set the water fill levels set to minimum (moved them up) to try to fix the problem, but that didn’t help. Any ideas what could be wrong? Did I make a mistake, is there a setting I forgot, or are they both faulty?

[@ReviewedByPhil]

So there are a couple things to try. It sounds like you've already tried adjusting the fill float level (see 3:14) by raising the float and allowing more water to fill the tank. If that hasn't worked, try adjusting the water usage floats (green and blue). Move the blue float up to use less water (see 3:24) during a quick flush and push the green float down to use more water for a full flush (see 3:34) and hopefully you'll be able to see a bigger difference in the volume between the two flushes.

[@christianbatista7974]

The bottom section won’t fit snug on my tank. Anyone else have this issue?

[@tyrehester5550]

Good explanation in this video. I’m still not sold on why anyone would want a dual flush toilet though, since you proved it might not work. Water is a cheap and abundant resource.

[@ReviewedByPhil]

True, in the US, water is inexpensive and averages out to less than a penny per gallon, so from a cost savings standpoint it may not seem like a great incentive. But viewing water as an unlimited resource ignores the fact that many parts of the US experience periodic or frequent droughts (roughly 30% of the country experienced some measure of drought as recently as last month according to the US gov't drought monitor) making water conservation essential in those communities during those times, which can last for months on end, or years in some states. Abundant may be the overall trend, but isn't always true for localized points in time in all places. Plus I think folks feel good about saving water to preserve the environment by way of reducing the energy required to process and deliver water, minimizing pollution vectors, and conserving related fuel resources. A quick note on why I think the dual-flush didn't work in our guest bath: we already had a water conserving tank on that toilet (hence its shorter height) and since it used less water than a standard tank (3.5 gpf), the dual flush wasn't really an appropriate modification because there wasn't enough water in the tank to make it function correctly and the conservation benefit was not as pronounced, though this was not realized until after I completed the installation. The conversion kits works quite nicely in our standard-sized toilet tank.

[@casaMN]

Hey Phil really cool review! thanks for doing it. I just installed one last night and have to hold the handle down to fully flush. do you know of any adjustments to make? or is it because my toilet tank is too small? Thx again!

[@ReviewedByPhil]

Yeah, it sounds like it's not getting enough water per flush. If you raise the float it'll allow you to get more water overall in the tank which might fix the problem (see 3:19 for adjusting the float leveler), but if you're already at or around the overflow tube level you won't be able to get more water in the tank which indicates the tank size is just a tad too small. The other option is to allow more water per flush, by adjusting the blue and green water meters (see 3:24 and 3:36, push them down for more water).

[@casaMN]

ReviewedByPhil thx Phil! I didn’t try to adjust the float!! I was just messing with the blue and green adjusters!!

[@sarahuhler6885]

Thanks for this you just saved my sanity

[@bruceluyendyk6053]

You didn't cover adjusting the mini-valve to avoid extra water filling the bowl. Why not?

[@mitchellmanor1970]

I have an old American Standard toilet with a date stamp of 1933. I installed the dual flush and the quick flush uses as much water as the full flush. So I put the blue quick flush adjustment all the way up and no change. I am wondering if there is something wrong with the linkage so that no mater which handle is use it operates as a full flush. Any suggestions?

[@ReviewedByPhil]

Hm, the quick flush is the inner "smaller" lever. If the blue float is all the way up and it's still using all the water in the tank, perhaps the handle is getting stuck on something? If the handle is held down or stuck and the flap stays open this would potentially use all the water in the tank every time. Perhaps the Danco techs can better help you out? www.danco.com/support/

[@mfengoog]

Don't know what the J-tube nozzle at the bottom of the valve for. You did not touch it in your video. Any idea what's it for? Thanks a lot.

[@ReviewedByPhil]

My kit didn't come with the optional J-tube so I could not cover it in the video. The J-tube basically stirs up the water that settles at the bottom of the tank each time you flush in order to help prevent residue/sediment build up in the bottom of the toilet tank, so its purpose to to keep the tank clean.

[@colindylan100]

Hi Phil , great video bud . But after installed , I still have some leaking and the water refilled itself after 20 minutes or so . Where should I checked to stop this issue ? Thanks so much.

[@ReviewedByPhil]

Leaking typically means the seal between the fill valve and opening in the tank is not watertight. This can be due to insufficient contact between the blue rubber seal and the rim of the hole (left a little gap) so pressing down a bit on top may help create a better seal. Just be careful not to overdo it because pushing the gasket in the hole too far can also cause leaking if the seal gets wrinkled. In this case the unit would have to be backed out slightly until the gasket is secure against the open but not forced down into it. I hope this explanation is clear.

[@cwaa5556]

Mine must be broken. It has the same flush for both options full and quick. I'm going to return it.

[@zubairmorshed]

Hi Phil your step by step instructions are awesome. I have installed mine last night,. It went pretty well except the fill valve keep on filling up every 5-7 minutes. I have tried to install the blue gasket into the drain so many times but nothing is working. Seems like there.is tiny leak somewhere. Do you have any advice?

[@ReviewedByPhil]

Hm, sometimes I've found that some folks were pushing the blue gasket in too hard into the hole which was causing it to warp/wrinkle. Pulling it out gently to relieve the excess pressure allowed the blue gasket to form a better seal. You should be able to tell if it's leaking there into the bowl because you will see the water in the bowl moving/rippling after the tank is filled. If you're confident that the leak isn't around the blue gasket for the main flush valve, is it possible that the water is overflowing into the overflow pipe because the float is set too high?

[@zubairmorshed]

Appreciate your reply, it turns out my toilet is not compatible when I contacted Danko.

[@sandyadams8580]

The hardest part was removing the fill valve nut on the old one. I had to cut it off because it would only unscrew about 1/4". The second hardest was adjusting the level of tank water because the fill valve and float wouldn't adjust to a higher setting. The J valve is the next frustrating thing. The instructions were not clear enough as to when to attach it and what function it serves. After reviewing 4 KZbin installation videos I took out the other part where the old flapper was to install the j tube. I'm not much of a repairman so some of the frustration is my inaptitude for this kind of thing. Now we will see how long it last as some comments are saying it will not be working within 3 or 4 months. One More Thing: Plumbers are worth their weight in gold!!😡

[@darrenclark5902]

Just installed one of these to fix a leaking toilet. Easy peasy to install following your directions, but still leaking. Any thoughts? In any case, thanks for the amazing helpful video.

[@ReviewedByPhil]

Thanks for the compliment! But I'm sorry to hear ti didn't fix your issue. What I found with the rubber seal gasket on the Duo flush is that it can be either too loose or too tightly seated in the hole that empties into the toilet bowl. If you adjust its position while the tank is full of water it might be easier to determine when you have a good seal. Trying pushing the entire flush control assembly down a little more to see if the seal is simply a bit loose; if the water stops leaking into the tank, be sure to slide the rubber retention ring over the overflow pipe down so it maintains the downward pressure on the assembly. However, if the rubber gasket is seated too tightly, this could cause a "wrinkle" or slight fold in the seal with the tank hole which can also lead to leaking water into the bowl. You can check by sliding your hand around the seal and feeling for any bumps along the edge. In this case you'd have to lift the assembly up slightly and see if it stops leaking. The other thing to look for is whether or not the tank is over-filling and the water level is too close to the top of the overflow pipe and water is running into the tank from there. You can adjust that by lowering the float.

[@richardtate5337]

[@ralfwinter2221]

@@ReviewedByPhil However the small valve that connects to the J-valve seats on top of my 'Tank Liner'. Even if I were to cut a small piece out of the liner to allow for the valve, the water stream would go under the liner, and thereby causing sweating on the tank. All installations that I have seen so far, are tanks wit out the liners in the tank. So my question is the same, does Danco have other models available without the J-valve?

[@ReviewedByPhil]

Hm, once that top o-ring on the overflow tube section has been removed, you'll need to remove the gap cam first (2:30), then you should be able to pull up on the bottom of the base assembly, and it should slide out of the tank hole.

Hi Phil great video! Say I installed one of these today and the flush converter is too tall by about 1/2 inch. I have an angled rubber gasket the bottom of my tank. Can I swap that out with a flat gasket to buy myself a few extra inches of clearance? Thanks.

Hm, I'm not sure. Typically the flapper seat is part of the overflow tube assembly, so if you want to convert from an angled flapper seat to a flat one, you may need to replace the entire overflow tube (of course, if the flapper seat is separate, this is not an issue). I know the Duoflush is designed to be compatible with both styles, so it's possible that you'll get a bit more vertical room by making the switch, though I can't say exactly how much.

Thanks Phil!....I did solve my problem though. I simply removed the top of the plastic housing with a screw driver. There are a few notched clips that make this easy. I then clipped off the top of the blue low flush ruler by about 1.5" and that did the trick. Its been in and working now for about a week.
