the flarer nis good for pipes that have been frozen youll not get those in a compression coupling

I did mean to use compression when you have imperial pipe work and want to convert to metrick Steve ! However I don't know after a pipes base been fleared how do you join them ?

When adding inhibitor or cleaner to a system, shut off both sides drain a few litres or so then use a 15mm compression elbow in the top of the rad to pour inn your chemicals...

To people in the know this is probably obvious but to me it's not, how does the 15mm elbow connect to the top of the rad?

i meant to solder especially where ya cant get at it again, the only prob with comp is that 3/4 to 22mm is proper baggy and needs to be tightend to death.

it only works on compact style rads with a 15mm bleed point/ plug you can remove Look back i posted a similar one to use a bent f/i and auto airvent body

No No No!!!

Never use a 22mm olive on 3/4" pipe as you must use a 3/4" olive on 3/4" pipe.

If you simply try and bodge and screw up a 22mm one tight or there's a good chance it will leak or the joint won't be tight when fully screwed up.

If you want to flare the pipe, heat the pipe end until really hot and allow to cool down naturally so as to soften it and leave it less likely to split when flared.

behave how many new plumbers keep 3/4 olives on their vans. a 22mm comp fitting will make a good seal if tightened enough and its not a bodge by any stretch of the imagination....like i said use flaring kit if you havent got end feed converters solder all the way...

It is a bodge. 22mm olives will not tighten properly onto 3/4 pipe. They are not designed for it, should there be a leak you will be held entirely responsible for using an inappropriate fitting. There are lots of things that new plumbers may not have on their vans but that is not an excuse for not doing the job properly. When you've turned up to a job, fitted a new boiler, fired it up and a fitting has blown off the other side of the house because it is a 22 fitting bodged onto 3/4 pipe you will know what a bodge it is.

re: Hints, tips & secrets of plumbing - No Banter please!

I always have 3/4" olives and 1" olives in my van as do my other plumber mates. A 22mm olive is a bodge. Crimp them up and there's a good chance they will crease and not seal properly or blow off - I have come across this after other "plumbers" have been on site. Exactly the same way as you don't try and solder a 22mm fitting onto 3/4" pipe but use a 22 x 3/4 reducer.

These details and others like them make the difference between a bodger and an expert.

I always keep stock of 3/4 olives and metric to imperial end feed couplings.

i keep a few convertor olives in the olive box tied together with a bit of solder same with the couplings saves digging through to find the right ones
