Difficulty accessing compression nut between joists.

[Madrab]

It's not that it isn't recommended, it just shouldn't be needed if the compression joint is made correctly.

Why don't you tell us johnyd?

Stronger mechanical fixing I believe was your bulls**t.....sorry, mantra.

Let's not start this argument again! As I said in my reply. In my opinion.....

Each to their own. If it reassures a plumber to use ptfe on their compressions. Then fair enough. But I would be expecting those fittings not to leak in the future. And in the op's case. They have leaked.

Not blowing my own trumpet in any way. But I don't use ptfe on my compressions and they don't leak. Maybe it's just luck

BTW Mr D, if I could be bothered to stalk a fool like you around, I'd be in some of the other sub forums.

As long as your appearances here are limited; in all your various login credentials; and you're well out of the cc, then fine by me.

A basin wrench should get in OK to tighten the nuts. I hope they're not over compressed??!!

Got them tightened up using a combination spanner (24mm and 32mm spanner). Got a basin wrench aswell for future use.

Getting someone in to replace with soldered joints.

Thanks for replies.
