There's a lot written on this! I have a top floor bedroom with a roof above it that is in two sections - one side is pitched with felt and tiles, the other is 'flat' with boards and felt. The tiled side appears to be ventilated, the 'flat' side is unventilated and cannot be ventilated. I...

Hi all, I cannot find a version of the Isar HE24 manual that refers to the older metal body type diverter valve. Does anyone know: To replace a faulty one do you need to change the whole manifold or is there access to remove the valve mechanism below the actuator, without removing the brass...

Which Seal is better?

Cat amongst the pigeons.....They have got that detail wrong. That's the whole fun of it. No government official or scientist has made rule of law or accepted theory on this. Perhaps a religious scholar can enlighten us?

"Thread sealants such as joint compound (pipe dope or thread seal tape such as PTFE tape) are unnecessary for sealing purposes on compression fitting threads, as it is not the thread that seals the joint but rather the compression of the ferrule between the nut and pipe. However, a small amount...

A fair few, I imagine, and smoked the lot all by himself.

High qualiity professional plumbing work requires compression joints that are tightened to the correct tightness, so that the pipe is not distorted and the olive can still be removed with an olive puller. It is also important that it is tight enough to prevent the possibility of the pipe blowing...

A small drop of olive oil works wonders.

That shut everyone up, including the pro's...!

One of the main advantage of Boss White (or similar) is that it acts as a lubricant so that the backnot turns more smoothly, rather than in jerks and squeaks, allowing the professional to asses the tightness as he (or she) tightens it. It also acts as a seal at microscopic level. I used to...

Fine, if you live in a Bodger's Hovel.

Fair dinkum, in times of trouble.....I prefer to renew the pipe end ideally, even sometimes I tell the client that if they don't want the whole heating circuit drained they can have a push fit on the radiator pipe at skirting board level.....

No but it is assisting the seal so the cowboy wot tightens it may not tighten it as much as they should - I have come across a few where I can undo the nut with my hand and slide the olive off freely.

"They" say that if you can look down the inside of the tube and see any slight indentation from the tightened olive, then it is overtightened. I would argue that a slight indentation is better than the risk that the fitting is not tight enough and may leak of blow off under pressure. The...

Better slightly overtight than undertight, IMO. http://en.wikipedia.org/wiki/Bodging

When it was said, in this thread, that PTFE was for bodgers, they were specifically referring to its use in compression fittings, not its other uses.
