End Feed Help

[seniorservice]

I try to use end feed fittings as much as possible, but often the fittings look over-cooked. The joints are sound, but the fittings have 'blueing' on them, and look a bit over done. I keep testing with the solder to see if it flows, but by the time it flows, my fittings are multi coloured.

I normally set my Bernzo TS7000 propane at a lowish setting. However, I saw the video below, and his gas is barely turned on. What do the pros do, minimum setting and take your time (as video), or have gas up a bit, and do it quickly? Any tips appreciated.

I cant say im a pro by any means.

my blow lamp is usually on the lowest possible setting, but my soldering is still shyte.

I was always told not to flux the female part of the pipe, only ever the male.

Medium to high flame as soon as you see a slight green in the flame (5-10 secs on 15mm pipe) touch on the solder until it whips around the pipe, practise makes perfect, leave a few seconds then wet rag to tidy up

Thanks for replies.

Think I may try turning gas up a bit first, and using less flux.

once you learn how little flux you need you will be onto a winner, i flux the pipe not the fitting, heat 15mm fitting for about 9seconds, then remove the blow lamp, apply the solder from the opposite side to the heat so that when the solder runs round you know the whole joint is done, clean off excess flux with a damp cloth or spray it with a household cleaner bottle filled with clean water

while im waiting the required one hour to check joint and surrounding area for any damage i complete my hot works certificate

Too much flux can sometimes obstruct the capillary action of the solder! not too much flux and only flux the pipe!

Ive never heard of having to wait for an hour to check the joint, Is this in the regs,

It's quite often a condition of your public liability insurance.

Would anyone happen to know the conditions of BGs PLI? We dont get an hour to hang around and check work

Hot works certificate, says you finish hot works an hour before you leave the site.

That also applies to most PLI.

it comes from the requirements of a hot work permit, which require hot work to be inspected one hour after completion to ensure the work and area are not smoldering away,
