are these materials safe to use for water changes ?

[stevediaz1]

hello I'm trying to create a system with a dual outlet y valve for my water changes to make it easier and i want to know if the materials I'm using are safe for my aquarium I'm not sure wether the materials I'm using are metal,brass & also the store had a zinc y valve but i didn't purchase it still i would like to know wether its safe to use so will some one tell me if its safe to use or not i tried to find plastic because its the safest i think but i wasn't available at home depot

Brass contains copper, copper is bad. I don't think I'd run zinc either. I prefer to have no metal in contact with water going into my tank.

It's not too hard to build something like that with plastic parts. I would use 1/2 inch pvc and pvc ball valves. Costs a little more than what you are looking at, but it's known to be reef safe. No risk of various metals leaching into your tank.

I wouldn't use any metal at all would stick with pvc or you can just get a python water changing hose set up can change it if you wanted so you could put a pump to return your ro or salt mix back to your tank .but defently no metal unless use use high end stainless.
