DIY Nappy Sprayer or Diaper sprayer

Hi everyone – welcome to our new blog!

I am going to start the Hatchlings Cloth Nappies blog with a blog post I meant to write over 12 months ago, that is right, I did the research, purchased all the materials and even had a trial run, but as we were having our bathroom re-tiled I thought I would wait till that was done as the pics would be better. Well our bathroom was finished Feb 2012 and I am just getting to it now, well better late than never right?

I shall start the post proper by saying that it is unbelievable that it took me so long to discover the joys of a nappy sprayer. I never bothered to get one when our first daughter was little because our laundry was in our bathroom and it seemed a bit of overkill but now that our laundry is downstairs under the house I needed to make other arrangements. Having tried the nappy sprayer I have nothing to say but OMG where have you been all my life. A nappy sprayer makes dealing with number 2’s so much easier, and you can clean the loo with it too! For those of you who have not seen one, a nappy sprayer is a hose that comes from the back of your toilet that you can use to spray the poop off your nappies directly into the loo – leaving them ready to pop into your nappy bucket or wet bag.

Nappy sprayers are of course available commercially, but the price is getting up there (from $50 to $90 plus postage) and a lot of cloth nappy parents are using cloth nappies to save money so I thought I would have a crack at a more affordable DIY option ($29.28 in materials). Here are the results:

The nappy sprayer is the white hose – you use it to hose the poop off your nappies directly into the toilet.

Pretty neat with all the extra pipes and things tucked around the back.

If you want to have a go at your own DIY nappy sprayer, it does not require any special skills or knowledge, and it does not involve using anything that you can’t get from your local hardware but be warned, I am not a plumber, and this is not meant as professional advice. If you are not confident that you can tackle this project, consult a plumber or purchase one of the many great commercial products available.

Ok, warning done, we can get on with the instructions

What you will need:


  • a shifting spanner (shifter/monkey wrench)
  • something to catch water (a plastic take away container or towel)


I purchased all of my materials at my local Bunnings warehouse and have included the prices I paid for your reference. I have also provided a pic – all be it a bad mobile one – of what everything looks like in the shop so that it will be easy to find.

  • 1 Trigger Sink Spray $17.98
  • 1 Mini Cistern Cock $4.10
  • 3 CP Brass Nipple Hexagon $2.40 ea
  • 1 CP Brass Tee $4.30
  • 1 225 ml flexible water connector $3.90
  • Teflon tape (that’s the white plumbers tape) I got 5 rolls for $3


1. First get everything out and lay it out like the picture below:

There are parts included in the Trigger sink spray that you don’t need – you only need the hose with the threaded connection(you can see this at the bottom of the picture above).

2. Next wrap all the threaded joints with teflon tape – you just wrap it round 5 or more times – I found that it paid to be generous here, preventing leaks later.

3. Screw together the cistern cock, the nipple connectors, and the tee and tighten them up firmly with the shifter.

4. Next go to your toilet and locate the cistern cock already installed that controls the water that fills your toilet cistern –  picture below.

5. Turn this cistern cock all the way off (to the right) and then flush the toilet. Next put your plastic container under the area and you can undo the hose that connects to the existing cistern cock (you might need your shifter) see picture below:

6. Remove the old teflon tape on the existing tap, replace with fresh tape and then connect the flexible water connector(new hose).

7. Connect the other end of the flexible water connector(new hose) to the tee end of the parts you put together at step 3 and the old hose to the other end of the tee.

8. Connect the Trigger hose spray to the cistern cock end of the parts you put together at step 3 and it should look like the picture below:

9. Make sure everything is tight and then your ready to test it out. Slowly turn your cistern tap on, your cistern should start to fill. Once your cistern is full you can turn on the new cistern cock that you installed and test out your spray (into the toilet bowl of course).

10. Make sure you have no leaks then your ready to go. I recommend keeping the cistern cock you installed (not the original one) turned off when your sprayer is not in use, to prevent flooding should the hose fail in any way. It also prevents toddlers from using your sprayer which could be very messy.

We also installed a 3m hook on the side of the toilet to hang the sprayer on when not in use.

  2. Awesome instructions – I installed ours today. Thanks!

    One comment – your photo shows 20mm CP Brass Nipple Hexagon but I think you must have used 15mm (I did).
