Hot Water Manifold
OK, this is NOT the most beautiful plumbing job I have ever done, but its functional. There are 8 separate Hot water connections coming out of this. 2 legacy connections, 5 connections to the new addition and 1 spare.

Why a manifold? It wall boils :-) down to how fast you can get hot water at the faucet. Each faucet in the addition is on it own 1/2 pex line all of the way back to this manifold. Now if we had installed this using traditional methods of 1 - 3/4 inch line with taps off of it, you would have had to run an additional 2 1/2 gallons of water down the drain to get hot water at the sink as compared to this home run setup. AND, if I had used 3/8 PEX, which is not that common around here, the water saving would have been even greater.

I soldered this up out of copper fittings instead of a manufactured manifold, partly because I couldn't find the number of outlets I wanted, and COST, those factory manifold are EXPENSIVE.

The reason there are 1/2 compression valves in there is because HomeDepot was clearing out their stock of valves and I got these valves for around $2.50 each. Cheap I know..
