easy water solution for a dog grooming bathtub

I got tired of being stranded with no way to wash a dog when I was out mobile with broken plumbing so I came up with this solution for emergencies. I liked it so much I modified it a little for permanent use and abandoned my traditional plumbing entirely and now use this system for my every day plumbing. Now I never have to chase down mystery leaks anymore. I can see my entire system easily and fix it myself.
For my permanent every day use I did set it up to run from the tank to a hot water heater, have hot and cold water available, and come from a faucet with an actual dog sprayer. All of that is done with simple hoses on the back of the tub. Easy to access and easy to replace. Plumbing doesn't have to be complicated. You can do it yourself!

This is a great idea, where did you get the foot peddle?
