DIY Tutorial: Make Your Own Diaper Sprayer

Editor’s note: After getting fed up with poopy cloth diapers (even with my awesome flushable liners I use), I decided it was time to look into a diaper sprayer, which is basically a kitchen sink sprayer on a hose which attaches to the toilet’s water line. I wasn’t interested in buying one for $40 from the diaper companies, so we started looking online on how to make one ourselves. Unfortunately I only found a couple of tutorials, with no pictures!

So, David will be offering his first guest post here on the blog with a step-by-step tutorial on making your own for about half the cost. These parts came out to around $20 at Home Depot and it took maybe 20 minutes to assemble. So without further adieu, I’ll let my knight in shining armor take it away.

So Nicole told me one day that she was sick of sticking her hands in the toilet to get Gigi’s poop off those cloth diapers. Before we started using cloth diapers, I would have never guessed that a kitchen sprayer next to the toilet would be so useful (when I told the guy at Home Depot what I was doing, he actually asked if I was making a bidet).

How to make a DIY diaper sprayer

Anyways, here’s a list of the parts I bought for this diaper sprayer. We looked at several versions on the web that used barbed connections and hose clamps. You will find that all the connections in this design are threaded and (probably) less likely to leak.

1) The first thing you need to do is turn off the water that feeds into the toilet supply line.

2) Next, unscrew the toilet supply line from the valve. At this point, I should tell you to make sure that you toilet supply line is flexible. The rest of the procedure won’t be possible if you have a rigid toilet supply line. You can replace your supply line if necessary (or just check all the other toilets in your house until you find a flexible one – that’s what we had to do). It is helpful to have a small dish to catch any excess water that may be left in the toilet supply line.

3) Install the Filter Connector Splicer (fancy name for PVC tube with threaded ends) onto the 1/4″ branch of the T-fitting.

4) Attach the toilet supply line to the upper leg of the T-fitting. For those that haven’t done much plumbing work (which includes me; I am only going off what I have picked up since doing this project), the connection on your toilet supply line is most likely 3/8″ compression threads and that’s what I have assumed as I wrote these instructions.

5) Now you can install the T-fitting onto the valve.

6) To prevent the head of the sprayer from being under constant pressure, install a shut-off valve on the end of the sprayer line.  Install the Compression Connector in the other end of the shut-off valve (you will notice that the 1/4″ pipe threads go into the valve and the 1/4″ compression threads will be free for now). This valve goes in between the Compression Connector and the end of the sprayer line (between the two gold pieces shown below in photo). See next step for photo of the valve.

7) Install the PVC tube onto the 1/4″ compression thread side of the Compression Connector.


8 ) As a general note, I was instructed by the guy at Home Depot (obviously not an Olympian) not to tighten the compression fittings too much. Doing so may shred the washers and leave you with a leaky system. Also, I realized as I was putting the instructions together that it’s possible to install the parts in a different order and still have everything hook up correctly.

9) Once all the connections are properly tightened, turn the water back on to the valve. You will need to play with the pressure to get the right flow out of the sprayer. Also, you may experience some odd behavior from your toilet bowl and tank(running water sounds). I have found that it is just taking the tank longer to fill up (I am not a toilet expert so there may be more to that explanation that I am not equipped to offer).

That’s it. You can now use it to get that poop off without sticking your whole hand in the toilet. And if you are really brave you can start a water fight with your kids (not recommended for bathrooms with carpet).

    Not sure what I missed but every connection except the one from the sprayer is leaking. And I added plumbers tape. So I unhooked everything in frustration after dyeing already frustrated from having to go to Lowes three times to find the right parts. Well now the hose going from the toilet to the water supply is spraying everywhere. What the hell happened?? I am pretty savvy at this kind of stuff so I am just very displeased and between the gas money and money I wasted on all of these parts, I would have just been better off buying a ready made one. Off I go to Lowes for the 4th time to return everything and buy a new hose for the toilet.

  2. Bob the Plumber says

    As a plumber by trade, I have to stand along side the comments by the other plumbers. A backflow preventer of sorts is crucial to the safety of the public health. While the probability that nothing will be contaminated is very low, the possibility is there and if it WERE to happen, could be catastrophic for those affected. Why do you think your tub spout is a couple inches above the flood level rim of your tub?? For backflow prevention!! Why do you think your sink faucets are above the flood level of your sink?? Ya, it helps to get a pot under for filling, but the real and most important reason is backflow prevention.
    Backflow prevention devices are in place and required under Board of Health and plumbing codes for a reason. People have died because of public water supply contamination.
    Don’t beat down your plumber. He has been schooled and licensed. The plumber protects the heath of the nation.

      And what back flow prevention device is installed on a garden hose? Or on a kitchen sink flexible extension hose? Can you conceive the possibility that this flexible extension head is dropped (submerged) into the kitchen sink filled with dirty water?

      Backflow prevention is mandatory WHRE IT IS APPLICABLE. In this particular case it does not appear so.

    • C. Nelson says

      I don’t doubt what you’re saying, but I think you’re really sensationalizing things for your own (or your colleagues) benefit. Plumbing is not rocket science. You don’t need a license to do it.

  3. Horton says

    It would be helpful if you had a picture or diagram of the entire setup assembled. Thanks for doing what you have though. This is a great idea.

  4. Candice says

    It seems that the back flow preventer is in fact necessary. Someone asked a question in this thread that was on my mind as well. If a back flow preventer is required by plumbing code, wouldn’t manufactured diaper sprayer kits include one? The answer is yes. I did a google search for diaper sprayers and found 2 brands that include 2 back flow preventers each. The first one is made by Bum Genius
    And the second one is made by Aquaus

    Now, the trick would be is if you could use these DIY plans, include the necessary back flow preventers, and still end up paying less than one that is already on the market. If someone has done it, let us know!

    Thanks for the instructions, but beware that the shut off valve you linked to may contain lead. When I ordered it through Amazon, it came marked “Warning: This product contains greater than 2.5% Lead and cannot be used in potable water systems”.

  6. Mommy of 2 says

    Would it be possible to have a detachable hose to hook up to the sink next to the toilet and just use that? The water supply lines are not flexible in our house.

    • says

      at one time we had a hook next to the toilet, but otherwise we just had it laying on the floor with the sprayer head sitting in a little dish behind the toilet. :)

    I got everytthat you suggested and it’s leaking from every thibg i put together. I dont know what to do. I tightened it as much as i could. Any thoughts appreciated


  1. […] We attached a diaper sprayer to the side of our toilet. This way we can easily rinse the waste from the diapers into the toilet without having to get the entire diaper and/or our hands wet. Spayers can be purchased from many companies but they can also be made. I found a great blog which gives step-by-step instructions for making your own diaper sprayer attachment. The website and instructions can be found HERE.  […]

  2. […] For poos, when baby was exclusively on breast milk her poo was pretty loose and so I would rinse the insert and outer if required under water in the laundry sink before putting it in the bucket. Now that baby is onto solids her poo has changed consistency so it can be put down the toilet and if needed I do a quick rinse in the laundry before adding to the bucket. (I’m looking at attaching a small hose to my toilet to help with this job) […]
