Research: Showing the flow of running an IF/else statement.

I was able to find proper clear hosing at Bunning’s warehouse but was stuck on whether to use regular hosing valves or ball valves. After extensive research into different types of valves to use I was unable to one with one input and two outputs that could only have one on at a time, so I decided to go with the second best thing; having one input with two outputs that have the option of having the left flowing by itself, right flowing by itself or both at the same time.

After talking to the workshop technician she had the suggestion of drilling a hole in the side of the ball valve so that I could insert the sponge inside and have easy access to re-soaking them with food colouring and also have a good way of secretly containing the sponge from sight. This was taken into serious consideration.
I decided to go with the regular hose fitting because it would be much more cost effective than paying for brass ball valves which would almost double or triple my budget.
