I installed a dishwasher...
It's connected by a 3/8 copper water line with a compression fitting. It has a really slow leak...1 drop in a few hours. Should I dissameble the fitting and put some pipe joint compound on the ferrule? Or do I need to go buy another assembly, install a new piece of pipe and start over... I wish I could solder the damned thing together,,,then it would never leak. This sucks

| Pipe joint compound on a compression fitting is useless. If you have the extra in the line cut it out and put in a new one. I would prefer to use a flare fitting or sweat the joint but fittings for 3/8 are hard to come by at home improvement stores. BEST way is to put the propper fitting on the 1/2 supply and run one of the flex hoses for dishwashers over to it and connect it that way. |

If I really have to, I can install a new piece of pipe...it's running off of a 1/2" pipe with a reducer fitting. The new whirlpool dishwashers use a brass garden hose type fitting with a 3/8" elbow with a compression fitting. |

The dishwasher is directly connected by soft copper tubing... I see the reasoning behind why the original installer did this...hoses can burst... |

If you are good with soldering you can swage one side of the tubing insert the other side and sweat it –– the home depot stores usually have a cheap swage inthe plumbing tools section I would try another compression first or just replace the ferrules ––the problem with soft copper is it can be out of round or have a scratch and thats it no matter how tight the fitting it leaks . The stainless steel flex hoses are no more prone to leaking or bursting than copper or compresssion fittings.

I'll just pull it out and do it over

Good luck! A few weeks ago, I spent about six hours putting in a dishwasher. Most of that time i spent in transit. Just as I connected everything, one of the old soldered fittings broke. So I had to start over. I took the fittings to Lowes, and was searching thru the pipe fittings, figuring out how to put it all together, and one of their plumbing "experts" wanted to assist me. After explaining what I wanted to do, she told me that it wasn't possible to connect a dishwasher to a 1/2in copper pipe. I continued searching and found one of those Sharkbite fittings –– worked great. |
