Wnen I decided to install a bypass selenoid valve on the toilet my first thought was a single valve used on dishwashers, mounted it and I wasn't happy ,the volume was too low, then I went to plan "B" a larger valve , evidently a dish washer doesn't need a fast fill. I went to amazon and found this

This valve has great flow ,can half fill the toilet bowl in 4 seconds. The valve is available in 12 or 110 volts, I had already wired the first valve at 110 V if I did it again I'd use 12V one.
I cut the white plastic hose on the toiles in the center, added a "T" fitting , I cut the cold water "pex" supply added a "T" , the valve is installed between the "T's" . I found a power supply and used a momentary push button switch .
My 5th wheel has a basement under the toilet so doing the plumbing and electric was easy.
Wish I did the modification a long time ago, it's soo convenient.
