Water Supply from Washing Machine Feed

No, full bore is fine.
Did you use the correct insert in the plastic pipe?

 

[Armitage Shanker]

I used the insert with the blue o rings because I heard they were better than the standard plastic ones (John Guest Speed fit Super Seal)

Did you tighten up the nut & olive sufficiently? Was the insert fully inserted?

 

[Armitage Shanker]

Insert was fully in and l tightened the nut and olive so there was no sign of a leak when water fully restored. I checked for half a day before allowing washing machine to be used. Maybe it wasn't tight enough given the pressure it was under when washer in use. I guess that is the most likely cause. Is it standard practice to connect plastic to metal iso valves without problems?

Yes it is standard practice. You can connect plastic pipe to any compression fitting as long as you use an insert and compress the olive enough.

When the pipe came out of the iso valve was the insert and olive left in the iso valve?

All a bit of blurr. I think the olive and insert were still on the pipe but not 100%. It could be that the insert was left in the iso. As I say all a bit of blurr given the panic at the time!

Yeah, looks like it wasn't tightened up enough. Is everything ok now you've used copper tails?

Wrong insert you need the one without the blue oring

As the depth isn’t enough for compression

 

[Armitage Shanker]

I appreciate your interest in this issue. Yes, I just put a three inch length of copper into the iso and joined it to the plastic with Speedfit coupler. I feel so much more confident about it and so far no trace of a leak. I saw the idea of using copper on compression joints and then join to plastic on a You Tube discussion thread. The arrangement was labelled as "bomb proof". I was so traumatized by what happened, I liked the idea of "bomb proof".

Thanks, I wish I had known that at the time. Because they have the rubber O rings and they cost more, I assumed they would give a better seal so I used that one in the compression joint and the normal ones in the other joints.
