strange thing for a first post but meh here goes.

totally noob grower here, but i have done lots of plumbing.

why wouldn't you just get proper copper t's and copper caps for your sinks, ten solder all of it together?

i just see a major safety issue here.

basically from a plumbing perspective, it looks like a kid tryin ta plug a square peg in a round hole. the fittings do not match the pipe.

otherwise, te idea looks solid.
