What does DZR stand for in Plumbing terms?
Dezinctafication process
Do you need a dielectric fitting for all different metal to metal connections such as copper to galvanized and copper to brass?
Yes, and make sure it has the DZR stamp of approval.

What is dzr brass made of?
Dezincification is a process of removing Zinc from the Brass,In potable water containing chlorine the zince from the brass gradually reacts with the chlorine in water leaving rich and porous copper exposed, to prevent this arsenic or tin is added so that the Zinc contain in brass is not exposed and so the copper Regards Ronald pate(Pune,India )
What is special about DZR plumbing fittings?
DZR fittings are brass fittings. Brass is an alloy made of copper and zinc.Zinc costs less than copper.Therefore, most brass plumbing fittings and valve these days contain too much zinc, not enough copper.The safe zinc content for brass is usually around 15%The problem it creates is called "Dezincification": when a brass alloy contains more than 15% zinc, there is too much zinc to "fit" into the copper matrix (between the copper atoms), therefore the zinc slowly dissolves and leaches out of the part. Visually, you may see a white powder at the surface (zinc oxyde) and very red metal (copper rich brass). The copper rich metal that is left is very porous because it has lost its zinc ! It becomes brittle and weak and brakes eventually.DZR fittings are garanteed to contain proper amounts of zinc.Dezincification is nothing new, except that manufacturers play the numbers game and prefer to occasionnally pay for losses and damages when a part fails rather than sell their stuff at a higher price. To them its only a matter of bottom line. To you, it can mean thousands of dollars of damages and hassles.
Are copper pipes better than iron pipes?
Red Brass = 85 % copper /15 % zincYellow Brass = 60% Copper 40 % ZincCopper TP is threadless pipe diameterCopper tubing Type K / L/ MSo what is tyhe application and working pressure?BEST application would be Brass (RED) and brazed joints with TP fittingsI would tend to agree but only if the brass has been DZR (dezinctified) treated, otherwise use copper.ONLY "Yellow BRASS" is subjected to dezinication as the 40% zinc causes piping failures as the pipe becomes more brittle over time
Can you mix brass pipe tee with galvanized pipe?
No you cannot mix the fittings, the properties from the galvanised pipe will weaken the properties in the brass. It is always best to either change or repair a pipe or fitting with the same material.
