What did i do wrong?

[Luggsey]

So, first plumbing job in years, bought solder, flux and MAP gas as shown.
15mm copper pipe, shined up, fluxed, absolute failure!
I'm a sparks by trade and solder a lot but not with a flame.
Am I right to assume map is far to hot for an amateur to work with, I cooked the pipe!
Advice where I'm going wrong please, I cant afford a plumber!
Cheers.
Paul.

As a follow up, these bits are for a shower mixer, can I use JG speedfit for the link to the shower head with the supplied compression fitting or must I use a plastic fitting?

 

[snowhead]

Waaaaay tooo hot.
MAP on 15mm is overkill but with care will work.

 

[Luggsey]

I thought so, better get a propane bottle then I suppose if that will work better for me?

 

[JCplumb]

You're using the wrong insert on that shower connection.

 

[Luggsey]

Is it going to get complicated and require bits?
I struggle to get out obviously at the mo.
Is it better to use copper and teach myself how to set copper pipe or is there an easy way to use the plastic?
Cheers

Way to hot bud 🔥 you can use it adjust the flame lower on your torch if possible , as for shower connection I would fit copper into the shower mixer then use a speedfit fitting to plastic . Regards kop

Too hot, way too hot. Mapps fine, it's all I use but turn your flame down and keep pulling away from work and test with solder. Get yourself some lead free solder as well if you're working on potable water.

That's a super seal insert you've used on the speed fit. Not suitable for compression fittings and wont be covered by warranty if it all goes breasticles up.

 

[Luggsey]

Second go with less heat, not good enough but I'll persevere.
Thanks for advice!

 

[Chalked]

Too much heat with the soldering. And the top shower connection
looks like it needs a swivels connector or a female adapter. It hasn't got a machine face for the compression ring.

Plus that’s leaded solder and mustn’t be used on potable water. You need lead free.
you will have better results with lead free solder too.

 

[Luggsey]

Its a Bristan and the compression fittings came with it?

 

[ShaunCorbs]

Sharp Stanley blade and cut the top side of the oring

 

[Luggsey]

Found this fitting, this looks like the right one?

 

[ShaunCorbs]

I would say it’s a compression end eg nut and olive straight on

 

[Luggsey]

Found enough plastic fittings and non return shut off valves, not sure how much support these pipes need, would one clip for the head feed and one clip above each shut off valve be about right?

Rather than apply the heat to the joint run the flame from say 1inch away accross the whole peice from inch away. Gently build the heat up until the solder just runs freely. Mapp gas gets up to 1600c and needs carefull experienced application. Go get a micky mouse diy propane To compare and start teaching yourself it’s a good skill to have. The opposite is butane in a cold house in mid winter took ages. Centralheatking

I tried as advised with the MAPP torch on the lowest flame it would stay lit with and had much better results, still not getting good solder flow but much better.
I just did a set in 15mm to replace the plastic feeding the shower head as it sticks out to far, not as good as my sparky tube but ok for a first go!

 

[ShaunCorbs]

Is it blobbing or sucking into the joint ?

 

[SimonG]

Plenty of flux on it and make sure its 100% clean. Plenty of practice as well. 👍👍

 

[Luggsey]

Both!
I think I need to shine the tube further past the fitting and use more flux!

 

[ShaunCorbs]

Are you cleaning both the fitting and the tube as for flux just a light coat all the way round the tube is more than enough

I'm gonna get plenty of practice, five bed new build, done 150sq m underfloor heating downstairs now starting on the showers!

Yep, shining them up but maybe I need to shine the pipe more outside the fitting.
I'll get there with help!

 

[ShaunCorbs]

It could be you have the flame too small now and all the flux is burning off before your adding the solder try turning the heat up a smidge maybe 1/3 of a turn on the valve

also Your using leaded solder switch to unleaded as you can’t use lead on water pipes these days

I will try that tomorrow.

I like the bracket for the fixed head

I didn't know the accepted way of doing it so I got creative, really easy to be honest!
