Going to attempt to install this myself after the tile guy does the demo. I looked at the instructions tonight and have these question. Did search the forums first, but had over 200 hits. So, here goes...
1.) There is a metal black filter screen in the brass body. I am confused on what this does as the instructions say to remove this when done and leave it in when you solder. It also says that to much heat can damage it while soldering. I want to just remove it while soldering. Why would it tell me to leave it in while soldering? And what does it do while flushing, are there internal passages I cannot see? Because it looks like the filter screen just runs to the 1/2 inch shower head pipe.
Here are the instructions that are confusing me:
"Remove bonnet (1) and test cap (2) before soldering. Leave screen (3) installed. Warning: Avoid soldering at high temperature. Exposure to high temperatures may damage screen."
"After flushing remove filter screen (5) and reinstall cap, bonnet and cover."
2.) It came with this reusable test plug. This plug will not fit in with the filter screen in place and if I put in the plug then the filter screen, the filter screen will not seat. Here is what the instructions say for this plug. "Used to plug one inlet side (Hot or Cold) to prevent cross flow when checking for leaks before the cartridge is installed. Insert into the inlet, place test cap and use the bonnet to secure in place." I do not understand this cross flow problem and why I need to stop it for leak testing.
3.) In actually testing for leaks, do I need some kind of valve on the shower head pipe to let the air out? Or will the water pressure be enough to get the water to the end of the shower head pipe?
Thanks, Tom

This is not the plug. This is a cap that comes with the valve that allows crossover. To prevent crossing over, this should be replaced by the plug.
