Here is what I've installed.
Here is what leaks. It's Blue Monster Pipe Thread Sealant.
Only the hot water "in" leaks. but I'm assuming this is not how it's done. I should have probably soldered the fittings after tightening them the best I could?
If soldering this close to the plastic workings inside do I remove them like I did for the mixing valve?
Any help/scrutiny/criticism is welcome and much appreciated.
