It is important to note that if you’re unsure, seek professional help and guidance on anything listed in this article.

Understanding Push Fit Flexible Hoses

Push fittings are the simplest connection to be fitted straight onto copper or plastic pipework as they can be fitted in a tight space without the need for tools. Whereas compression fittings need to be tightened with a spanner. This can often be difficult in confined spaces in a cupboard under a sink or when connecting a new bath. There are countless types of pushfits from many different suppliers, they can be metal or plastic which are commonly supplied by John Guest Speedfit Range to the plumbing market. Hydraflex can offer Plastic John Guest fittings or our own metal fittings depending on your application, temperature and pressure requirements.  

Tools and Preparation

There is not an exhaustive list of tools that are required when disconnecting and fitting a flexible hose with a pushfit connection but like most tasks the better preparation leads to an easier installation process. Tools that would be helpful for this are as below:

  • Torch 
  • Pipe Cutter 
  • Deburring Tool 
  • Appropriate PPE 

It is important to note for this blog that it will focus predominately on the fittings of a Hydraflex pushfit assembly onto copper pipe work and there may be some differences if being used on plastic piping or fittings. Normally a pushfit for plastic pipe requires the appropriate insert. 

Step-by-Step Guide to Removal

This is all dependent on what type of assembly or connection you currently have, in this example we will be looking at removing a like for like pushfit hose. For any other assemblies or connections, it is recommended to review the manufacturers instructions on how to do this. Ensure the water is shut off and the system is drained before beginning this process. If there is space to do so it is always a good idea to place a bucket under the pipework to catch any remaining water that may still be in the assembly; or a towel to mop up any additional water.

  • Step 1: Identify where the push fit connection is on the pipework and remove any collet clips or locks.
  • Step 2: Hold the body of the fitting in one hand and the collet in the other. 
  • Step 3: Apply pressure on the body towards the collet while gently pushing the collet to the fitting.
  • Step 4: Pull both the collet and body of the fitting away from pipework to release the fitting. 

On occasions original installers can create future issues with a set-up that’s virtually inaccessible post-installation. In this situation, hard-to-reach hoses are tough to remove or replace. It might be necessary to use a pipe cutter and then dismantle the push-fit fitting to remove its remnants. Then, either a replacement pushfit pipe or going in a different direction, this is the ideal application for a Hydraflex pushfit tap flexible hose. 

When discovering fundamental issues with plumbing installations, it’s best to seek the help of professional plumbers. They’ve seen these kinds of issues before and can make sensible recommendations on how best to proceed.

After Removal – What Next?

There are a few things to look out for when you are ready to fit a new hose, it is essential that these are checked before you attempt to fit the assembly. This does not just apply to the pipework as there are several things that need to be checked on the assembly. These include but are not limited to:

  • Are the end connections correct, do the fittings and the size of them match what you are trying to connect?
  • Is the hose long enough for where you are trying to fit it? It’s important to remember that flexibles hoses should not be fitted tight and there should be a bit of slack in the hose for movement in the application. 
  • Is the pipework clean, undamaged, burr free and not misshapen? If not, would it be best to cut the pipe back and then deburr it? A burr on copper pipe work can be sharp enough to cut the seal of a pushfit connection when fitting, this could mean an immediate or future leak after installation. 
  • Is there any flux on the pipework? If so, it is critical to remove this as flux is very aggressive to the plastic collets and stainless steel braid. This will cause failure over time, which could be weeks or years, so it is crucial to be certain.

Step by Step Refit

Now that the pipework is free of flux, clean and not damaged with no burr it is time to fit the new hose. This is a simpler process than removal and is only three steps once the pipework is prepared. 

  • Step 1: Ensure that there are all parts in the pushfit that is required, this includes a washer, an O-ring and a collet. On occasions there can also be a clip, this must be removed before the next step. Hydraflex’s metal pushfits will already come assembled for easy installation. 
  • Step 2: Push the fitting onto the copper to ensure that there is good purchase on the pipework.
  • Step 3: While holding on to the pushfit gently pull the fittings back away from the collet to cause a grip onto the pipe work. If a clip is supplied, then it should be applied between the collet and the top of the fitting to secure the pushfit. Pull down on the fittings to make sure it is connected as a final check. 

Conclusion

These steps should ensure that you are able to complete the changing of a Hydraflex flexible hose with a pushfit, by following the two step by step processes. It is important to have confidence in this task but approach it with the caution and preparation for issues along the way.
