Not 'Earthed' but bonded. No earth bonding is required if plastic pipe is used for flow and returns to radiators. The water in the pipe can neither introduce a voltage or act as a path to earth.

All other copper or metallic pipes / metalwork does require bonding to comply.

What you have is a tail piece coming down from your sink. Onto that is a slip nut that simply slips over the end of the tail piece, with the threads facing down. Then a semi-transparent gasket referred typically as a washer, which is tapered, is pushed onto the tail piece to hold on the slip nut. This washer makes a type of compression seal between the slip nut and the threaded end of the j-shaped pipe (called the trap). When you push the trap up onto the tail piece, depending on how the pipes line up, an inch or more of the tail piece will be inserted into to trap. Then you push down the washer, with the tapered side facing the openning of the trap, so that it fits in like a wedge. Then you slide down the slip nut, and tighten, but no too tight. These nuts are known to actually split and/or strip. And also the washer can get shredded or bound up in a way that you don't get a good seal if you overtighten. Even when it's propertly installed, if you push down hard enough of the trap, the connection will seperate... remember its just a very light-duty compression fitting. For this reason, the tail piece has to be cut long enough so that it extends down into the trap below the point where the slip nut is connect to the trap threads. It is very unlikely you need to replace your trap unless the male threads are stripped... more likely the washer is fragged. Possibly the slip nut may also need replacing. And... if the tail piece was cut off too high, then you need to install a new tail piece (they come in a couple of standard lenghts, and then the plumber will cut them off to the right lenght with a hacksaw on site); the tail pieces sold in places like Home Depot or Lowes usually comes in a whole kit with the sink strainer. They are pretty cheap even for the kit. You do need some plubers putty to make a gasket with your sink, and for that job, you should really get your maintenance guy to do it. Regardless, you should not be using any pipe dope or teflon tape anywhere on these drain connections. Good luck.

Some of you are a hazard (not all)!!! Do you actually know what you are talking about. My simple answer would be to contact a COMPETENT person!!! Plumbing in a property should be bonded (earthed) in the correct way. Legally Gas and Water HAVE to be. Earthing merely moves the voltage to a safe place (ground) through the cable and NOT YOU! I have been on a job where a washing machine case has blown a hole in a cold water pipe! NO SUITABLE EARTH the cause! Stray voltage can happen for a lot of reasons. Heating systems can normally be earthed actually at the boiler piping. If in doubt consult and elctrician, not wannabes as seen here!

A radiator is not an electrical appliance, merely a distribution device for warming the surrounding air from the hot water within it. The electrical device which feeds it, the pump, should be earthed as should be the boiler which feeds the pump.If in any doubt consult an electrical engineer.

It would not be possible to earth a radiator with plastic pipe, in fact it could be dangerous in certain circumstances.

I wouldn't think so the Rad's I've fitted with plastic pipes haven't been earthed

Quite simply NO.It is not necessary to carry out supplementary bonding if tubed with pvc pipes.

Presumably these are water-filled radiators. No need for earthing.

I don't think so as the water system is earthed further back, you could add a earth strap but it would be hard to find any where to connect it.

No they do not have to be earthed even with copper pipes.
