Picture of How to build a diaper sprayer
If you are cloth-diapering your wee one, you’re quite used to being called a loon.  If you are planning to build your own diaper sprayer, you can add at least one more person to the folks who think you insane, the plumbing associate(s) at your local home improvement store.
This DIY will show you how to build a higher quality (and safer) diaper sprayer than the commercially available units for the same price or even a bit less.
A diaper sprayer is basically a sink sprayer connected to the toilet which allows you to spray the poopy mess into the toilet while keeping your hands cleaner than the old dunk and swish technique.  Many of the commercial units are just a sprayer tapped into the toilet supply.
My improved design has a shut off valve to take the pressure off of the sprayer when it is not in use and a check valve to prevent fecal contamination of your household water supply. This assembly uses a length of tube so that it can be mounted away from the existing toilet supply valve. The remote installation ensures that when you turn the valve several times each day, you are not transmitting forces to a valve designed to be used a few times per decade. The entire thing is mounted to the wall using bell hangers.

Wow, I have often wondered if I could make my own diaper sprayer as I think $40 is WAY too much to purchase one. I've often reverted to taking the messy ones outside & washing them out in our grass with the hose sprayer. THANK YOU! Some how, I am going to have my husband or father do this project for me. Awesome Instructable.

Straycatmeow, This cost me about $30. It would have been more than $40 if I had to buy the sprayer head. That being said, none of the commercial sprayers have the check valve which prevents fecal contamination of your plumbing. It's a very low probability event, but it is possible, either through splashback or dropping the sprayer into the toilet bowl. Also, the commercial units I've seen for $40 are all plastic. the reviews often mention leaks.
This doesn't get the pressure you're getting from the garden hose, but it is a lot more convenient. Also, I wouldn't want to use the garden hose in January. When you do use the hose, make sure you're not in the same spot every time. Your lawns can deal with a limited amount of feces, but when you overload it, your family and neighbors will be very irritated.
Thanks for the all the info. I am lucky enough to have not 1 but 2 builders in my family. My father and father in law both build custom housing/ commercial properties. I will 1st check with both of them to see what materials they have on hand that I can use. Besides, I'm hoping to sweet talk my dad into doing the whole thing for me. You are right bout' not using the garden hose during winter though, usually I cheat and go with disposables during part of the winter months because I have a heck of a time drying the diapers. As for neighbors, I have none really. I am out on a farm.
$40! you got to be kidding! over here it's like 2 to 3 dollars...of course if you bang it up or pull the lever up too much as kids tend to leaks...but all in all ...compared to the price over there...i think it's ok :-)

I plan on sending the link to DH, who has wished for a bidet forever. No room for one makes this a great alternative.

Please share this 'structable.
The only issue I would have with using this as a bidet is that this water is going to be COLD!!!!
I don't have any hot water pipes on this side of the bathroom, but DH might want to see about adding a mixing valve if there is a convenient hot water line to tap into.

Okay I'm pretty much on the side of those who see cloth diapers as a looney idea in this day and age, except for using them (new and unspoiled) as a polishing cloth for my 1930's vintage Model A.

However...this idea has a lot of practical applications for (modern) bathrooms above and beyond your stated purpose. I have a shower (no tub) and find it messy just to fill a bucket with water. The steam vac is another good example of that - the reservoir doesn't fit in my basin, so to fill it I have to use the shower and try to aim for the little fill hole. Having a sprayer like this would be VERY handy.

It could also be a great self-defense tool in case someone walks in on you when you are indisposed! :)

Very, very well written 'ible. Keep up the good work!
Cloth diapers have several advantages over the disposable ones: no plastic, reusable (meaning over the long haul they are cheaper), keeps the landfill load down, and my fave: they make the best rags for refinishing furniture - or polishing it - when worn soft.

Now, that's not to say that disposables whilst camping and the like are a bad thing because there are times when cleaning facilities just don't exist, but on the whole, there is a very large place for cloth diapers. Cleaning them's no worse than cleaning a cat box.

You drive an eighty-year-old car, but think cloth diapers are loony? :-)
Yes, this will be used for filling the humidifier come fall. Also, I'm looking forward to having these diapers used to polish a classic car when my wee beastie is done with them.
Also, there are two reasons for the isolation valve; the first is to keep pressure off the sprayer when not in use; the second is to make it less likely that a toddler discovers a squirt gun that never needs to be reloaded.

Not sure, but you might be able to enter this in the Water Challenge.

Thanks for the heads up, Browncoat. I posted a comment to enter, waiting to see if the folks at Shift feel it qualifies.

This is GENIUS!!! My mother would have killed to have one of these back in the day. She had 9 children most of which she used clothe diapers for. I remember her using the dunk & swish method. I myself use disposable diapers but I have friends who use the clothe diapers. I will have to pass this along for sure! Thanks for the awesome share!

Thanks for the feedback, Mygibzone. Having used this for a few days now, I can say it is awesome. It almost makes me look forward to a dirty diaper. I'd be more than happy to answer any questions that your friends have.
