use compression or solder?
Hi,
I am wondering how "safe and effective" is to use compression method instead of soldering for joint of copper pipe and fittings? I am not comfortable with soldering, but not sure using compression is "water-tight enough" for joint or not, thx. |

If done correctly the compression fittings are just as good as the soldered connections. I work in a very large plant and we have thousands to millions of copper and stainless steel connections using the compression fittings. Anywhere from a few pounds of air to several hundred psi of various chemicals. |

Mostly used for attaching faucets and toilets to the main line. If I was plumbing a new house today, I'd use Pex tubing. |

For the most part (in typical residential plumbing) hard copper pipe is
soldered except for a few things like supply valves at sinks, After that they are useful for repair but I wouldn't use them in a new setup if only for the vastly higher price per connection. Soft copper tubing usually uses compression fittings. Besides do they even have compression fittings for elbows, tees, 45s, caps. One great advantage for repair is that they can actually be connected without shutting off the water (yeah, its messy and you probably need to open a faucet to keep the pressure low) or completely draining the pipe. wrote in message oups.com...

I like to replace the supply valves for my cloth washer and other supply valves under sink. I guess that soldering may be the better option here. Thx. |

I agrre with all the above posters who would not use a compression
fiting execpt in places where they can see it (although I don't even use them there). I simply don't trust them. |

Probably OK for that but I prefer to solder on a male threaded adapter then attach the valve to that. Makes it easy to change out in the future. |

use compression or solder?
I am inclined to solder, but in a house I had for 35 years, I was
reluctant to solder some pipes near the water meter. I was putting in a "wet" darkroom for photographic work. I made it a point to CLEAN the tubing well, and to lubricate it well (threads, pipe) before using the compression fittings. For the 4 additional years I owned the house, I had no problems at all with the compression fittings. Clean was the trick, I believe. |

I am able install successfuly a water hammer arrester for the dish washer using two soft copper pipes. It seems to me that only soft copper is suitable for compression fittings at least as the Balck & Decker home repair book suggests. But the book also mentions that copper with type M is also suitable for compression fittings. The house I own is over 25 years old, not sure what type of copper was used originally. |

Please write us instructions how to "done correctly".

That makes for a good seal, and also easy service. You can also
compression on a valve. Seen em. -- Christopher A. Young You can't shout down a troll. You have to starve them. .. "PipeDown" wrote in message news Probably OK for that but I prefer to solder on a male threaded adapter then attach the valve to that. Makes it easy to change out in the future. |

Did you also notice that that plant has an entire crew of maintenance workers to constantly check and repair anything that breaks or fails? And hundreds of instruments in the control rooms to let you know when something is leaking or losing pressure? If you have those in your home, and all of the compression fittings are exposed, then I would recommend going with the CFs everywhere. -- Robert Allison Rimshot, Inc. Georgetown, TX |

I've had problematic compression fittings over the years... Often I get fed up enough with them and change them to flared fittings... It seems that with compression fittings, there is a certain amount of force that you can use to tighten the fitting -- too little and it will leak, too much and it will deform the fitting and also leak... With flared fittings, it seems that you can really torque it down and it won't deform and start leaking... YMMV, of course... |
