About five years ago we got a diaper sprayer and hooked it up next to the toilet. It was some brand bought off of Amazon. That sprayer worked perfectly up until about a month ago, when I noticed drips on the floor. I tightened up all the joints several times, but the drip seemed to get worse. Last Saturday I investigated in earnest and discovered a hairline crack in the stainless steel body of the diversion valve. My wife went on Amazon to see if we could buy a replacement valve, but it looks like that brand has gone dormant, everything is out of stock. So I asked google for diaper sprayer reviews, and that just listed various brands on Amazon. So then I searched for "diaper sprayer tvalve" and it sent me to
Potty Pail.com
Specifically, it sent me to their parts page. They make complete diaper sprayers, in the USA, with a lifetime warranty. But they also sell their parts. They say that their valve has a 1/4" NPT fitting that accepts almost all aftermarket sink sprayers. So I am going to check the sprayer that I have to see if it will fit. If it will, I will give their adapter and valve a try.
