 | Tips on using end-feed plumbing fittings? |

Question: Following swiftly on from yesterday's plea for help using microbore tubing (for which, many thanks for the replies!) I've been to buy various fittings from the plumber's merchants and foud that the range of these is graetly restricted in Yorkshire fittings compared with end-feed items (presumably because that's what the pros normally use). So I've decided it's time I bit the bullet and started using end-feed fittings, Should save myself a few bob too! I'm reasonably experienced with Yorkshire fittings and have no problems using them. What I'm not clear about, in transferring my skills to end-feed fittings is (I think) how you tell whether you've got solder down the copper-copper interface, and enough of it to make a proper joint? Easy enough with Yorkshires, when you see the silver ring appear...
Answer: If anything I find them quicker and easier than solder ring fittings since they (having less metal) get to the right temperature slightly faster. Prep and flux as usual, apply heat to the joint and wait a few secs, then offer up the solder to the joint and touch it on to see if it is hot enough to flow. Once it is, the solder will flow easily. Feed in about half an inch or so (assuming you are using typical plumbing thickness wire). You will actually see the joint suck the solder in. Once you have added solder, withdraw the heat, wait for a few secs and then wipe of any excess with a damp cloth for a neat finish.
