Sweat vs Threaded Valve

[supernewbie]

I'm trying to remodel my small bathroom and I'm at the stage where I need to replace the shower valve. The shower valve I purchased was a moen posi-temp shower valve from Lowes which is threaded. So far most of the comments on the internet favors sweat valves over threaded valves. I just wanted to know what your opinions are on threaded vs. sweat valves.

I also saw a video where a guy connected a male/male coupler onto valve and a male adapter to his hot and cold lines then connected the two with a braided line. Would you guys recommend this?

I personally like this idea as a quick way to replace the fixture, but just understand it will be the "weak link" in your water system because their life expectancy is much shorter than copper lines directly attached.

I don't have a problem with threaded joints. Make them up properly, test them well, and it shouldn't ever be a problem.

As far as the braided lines. You are still going to have to sweat the adaptors onto the copper pipe. Why not make a few more sweat joints and be done with it? Just make sure to sweat a short piece of pipe into the male adaptor before you thread it into the valve so that the thread sealant doesn't get exposed to high heat.

using flex connectors probably not a good idea. Soldered joints would be the best way, less fittings. The threaded adapter still has to be soldered.

Hi

I personally feel that threaded valve is the best to use.

Why do you feel that way?
