I am going to assume of the cost is minimal is a factor but how much quicker and easier to do a single drop header vs what I see here a lot which is a double drop header, on small residential ( union steam 125,000 btu ) is it necessary to use a double, my supply house says just go with a single and that is his own opinion, he also says that even just a single drop header is giving the customer a better product.
