Plumbing question

stranger12

Hi guys,

I was told by a plumber that too much flux can put a whole into a pipe overtime as it rots. He said it needs to be removed when hot

Is that true? My experience while doing plumbing all of my plumbing work was you need sound amount of fluz so the solder is released easy

I have done all of my soldering and did wipe it off aftwr when cold but can see green bits in some areas. I tried a water and cloth and all come off.

Should i use some stronger cleaning material?

Thanks

What does it say on the tin/tub of flux?

My plumber blamed too much flux when I called him to fix a pinhole in a pipe in the loft. I've never lived in a house long enough to know if I use too much!

How would you remove it?

Soapy water.

I thought there was more than one kind of flux, one of which wasn't as corrosive? You can neutralise acid flux with bicarbonate of soda from what I understand.

Yup, two basic types of flux out there. Rosin flux is non-corrosive and is normally used for electrical work - The trade off is that the parts to be soldered must be very clean.

Acid based fluxes can be used on slightly corroded/grubby parts and should be cleaned off with warm soapy water afterwards - Because the acid fluxes are more soluble in water, they are preferred for general plumbing work. Rosin fluxes will leave tap water tasting funny for quite a while.
