You are not dumb, you got this far.

 

@Nickfromwales was meaning loosen the nut against the tap a little this will allow it to spin,

Then if you have the spanner handles close to each other so when doing up they close up the gap(kep fingers out of the gap it can hurt if it slips😂). You should not turn the pipe, then tighten nut to tap.

 

Did the tap and all pipe work spin under the floor? As nick said get this connected and see if the other leaks.

 

 

I tried that I got it as tight as I can get it.

by god it was hard to do for some reason.

It’s not leaking at the moment. Just seems alien to me that the olive isint compressed into the pipe. 

yes the pipe work did spin under the floor multiple times believe it or not when I was trying to tighten the nut.  

I assume this is bad? 

The brass that the olive is trying to compress into is harder than the olive so won't deform, it's normal.

 

It may have a joint under the floor that is designed to spin hopefully. You will just have to keep checking for leaks. Is this a concrete or wood floor, if wood can you take any up to check it?

No it’s osb decked. It’s all in press fit.  If that makes any difference? I haven’t noticed any leaks yet or random booster pump cycling.

1st floor or ground floor?

 

@SimonD can press-fit elbows spin? 
 

Who else uses these? Anyone?

Not sure as I "don't do pressfit".....

 

The two nuts can be pulled towards each other and the pipework below can be kept 'still', if you connect the flexi only a few turns hand tight onto the bath tap first, then finish tightening, and then go back to do the final tighten on the bath connector last.

 

You can balance how much you pull on each spanner until tight, without transferring any rotational force 'down below'.

 

The answer to the question "have I fecked it?", will be answered when the pump kicks in fella. Just suck it up and whack it on, the worst thing that can happen is in that link.

 

Crack on   

That’s it now as right as I can get it with reasonable sized spanner’s. It’s came to a hard stop.

The olive still can slide off the pipe when I reopen the joint to check.
This is expected with brass? So won’t blow off on me? Thanks

The press-fit I can see earlier in this thread are MLCP - and yes, the pipe can spin in these fittings.

If any of it is copper press-fit then no, but there are times when brass press-fit level ball valves can 'wobble' on the copper pipe they're pressed onto (it's a bit nerve wrecking but fine).

Cheers 🤝👍🫡

Nickfromwales has given you the right steer here. That braided section right at the connector is exactly the spot where I see these flexis let go later on, so replace it while it is on your mind. It is a cheap part and it is worth it to not have that worry hanging over you.

Are corrugated stainless steel flexi connectors a better type, or are there any downsides?

I ordered a sample from them - arrived a couple of days later - I have to say I am quite impressed

All the advantages of flexi's but with a larger internal bore compared to a std flexi which means my gravity feed taps will like them

I will be ordering them for the kitchen replacement as I've been replacing flexis on a regular basis (5 years) since one failed
