Fibre plus jointing compound ?????

[CmdrBond]

I reading the installation instructions for the Trevi Boost.

I'm a bit confused by them.

For satisfactory flow performance, the pipework should be a 22mm copper on the hot water supply and at least a 15mm copper on the cold water supply. The connectors should be jointed to the valve body using traditional fibre plus jointing compound. (If PTFE tape is used special care must be taken to ensure the joint is water tight before plastering the wall).

Does this mean Fibre washers and a compound such as plumbers mait or BOS white.

Or does it mean to use hemp? Would the jointing compound be the same as mentioned above?

I'm a bit surprised that they would be suggesting hemp. Is it really better than PTFE? That's the only reason I could see for using it.

If they're referring to a threaded joint I'd use Loctite 55

must be like that green stuff jointing compound that i threw in the bin.

No, 55 is the plumbers dental floss.
