Shower Body Identification

I am adding zones to the existing water heating system. From the picture you can see starting from that pointed thread connection, the new addition is on the right side. From left to right after the male fitting, there are a 45 degree turn, a tee, a 45 degree turn and a tee again. They are located closely. My question is what's the sequence to join them together? I am thinking the following sequence: 1. solder the first short straight section with male fitting offline; 2. put above unit in with thread sealant and tight them; 3. solder the first 45 elbow and others online. does above sequence sound right? at step 2, how to prevent the heat being transferred to the new soldered join and the thread? use a damp cloth? thanks,

Hello all.. I had a leaky Moen single handle faucet. I replaced the Moen 1225 cartridge which seems to have taken care of the leak. Now when I have both the cold & hot water supply on under the sink I can't turn off the faucet. When only 1 of the cold/hot water supply knobs is on, I can turn off the faucet. [COLOR="#0000FF"]Any ideas?[/COLOR] General Question A single handle faucet a. turns left and right (currently turns water on/off) b. shifts up and down vertically (currently doesn't do anything) [COLOR="#0000FF"]What is each of the above actions supposed to control?[/COLOR] [ATTACH]40085[/ATTACH]
