The polytetrafluoroethylene tape range comes in gas grade and potable (drinking) water grade and is available in singles or multipacks.As it doesn’t set solid any exposure to pressurised water can easily just wash it straight out of the joint. Clean all threads: The first task is to clean everything fully and remove any dust, debris or grime that may be in any of the threads.

They’ll make sure the job is done right so you don’t have to deal with the headache of a leak down the road. In terms of this it is recommended that you don’t use any more than 3 complete wraps of PTFE tape around a thread. Just make sure the water is off, then unscrew the shower head and arm and wrap the male threads 2-3 times with plumber’s tape, then screw everything back together and test the shower. You’ll find the tape material is stretchy, allowing you to wrap it tightly while the material is able to conform to the threads of the pipe.As we have discussed above, PTFE tape can be used on pretty much any domestic water-based plumbing system to help prevent the potential of any future leaks forming. That being said we have found in many situations that despite not tightening a compression joint too much and doing everything that’s required to ensure a successful joint, the slightest pin prick hole can cause a leak and adding a little PTFE tape to the thread can certainly prevent this. Screw joints together: Run your finger over the loose end of the PTFE tape and push it down into the threads to prevent it coming out when you start screwing the joint up. it would also do a poor job of shielding you from electrical shock, so don’t use them interchangeably. If any more than this is used, as the joint is screwed together it can cause the tape to ruck up in the thread and in turn create a void that can then easily lead to a leak.

When wrapping PTFE tape around a thread each revolution or layer should over lap the last one by roughly a half to ensure a good seal. Although it may seem that you can use PTFE sealant tape with pretty much any water, fuel or gas system, this isn’t quite the case however as pretty much all compression fitting manufacturers recommend it should not be used on any form of compression joint.One important point to note is that Plumbers Mate should not be used in any areas where is it exposed to pressurised water.

The most comprehensive and detailed guide on how to troubleshoot and fix any problem your electric water heater may have. For example, hold the pipe fitting horizontally in your left hand with the threads facing your right hand, then position the tape with the end facing down, so you will wrap the tape away from you. Piping systems and additional piping that use oxygen need a specialized thread tape for their sensitive system.

You don’t need to use plumber’s tape on unthreaded joints, which you should use a liquid sealant for. As you overlap the tape, work gradually away from the end of the pipe to completely cover the threads. Shower heads and arms, which are the metal tubes that shower heads attach to, are another area that tend to have problems with leaky connections. PTFE tape is more of a preventative measure employed to help minimise the risks of any leaks forming in the future.
