I am installing a brand new shower with a Delta manifold. It has threads for each connection (hot, cold, shower and tub). 1/2 copper also fits into the connections perfectly.

I have already used this same configuration on my other show that I installed, I soldered in the copper pipe. Yes it took a while to get the brass hot enough, but I have not had any leaks for over six months.

I went to the local home depot about getting a plug for this installation, and they told be that I should not have soldered in my copper connections since it was threaded. They said I should have used the screw on connection then solder to that copper fitting.

Can anyone give me any information on the pros and cons of both ways?

The sweat fitting are better for me because it eliminates one solder joint and one threaded joint on each side of the body. But be sure that you take the valve apart and take out all of the parts that heat could damage or distort.

Screw on fitting (female adpator) is to make the job more home owner friendly. Soldering is best but requires a bit of skill and some disassembly as Letmetellu points out. A properly taped and tighten adpator should be fine but I sweat whenever I can.

Hi Mike...

Delta and may other manufacturers are making valves today that can have either pre-soldered threaded female adpaters connected to the male threads of the valve OR can have copper pipe soldered directly into the threaded connection as you indicate you did.

You will have no issue with this the way you have done it! As presented, you did exactly what the manufacturer wanted you to do!

Good luck...

THanks guys!

Glad to help!

I am a bit late but... Basically, manufacturers give you both options. There is nothing wrong with either one of them. Some prefer to solder, some prefer to screw.

Some prefer to solder, some prefer to screw. Given a choice I'm going to chose "screwing" every time. LOL!
