Push fit fittings – Plumbing Tips


Plumberparts.co.uk Honest reviews and advice. Hello. This instructional video will show you how a push fit fitting works and how to install one. Let’s look how the push fit fitting is assembled. There is the main valve body, the rubber seating washer, the washer jumper that holds the rubber washer in place, the pipe clamp that holds the pipe in place, and the end nut that holds all this tightly together in one piece. The rubber washer is first inside the fitting, then the washer jumper, the pipe clamp, and finally the end nut. If we look closely at the pipe clamp we can see it has metal teeth that grip the pipe one way so you can push it on the pipe but not pull it off. Push fit fittings can be used on both copper and plastic pipe. Plastic pipe requires a small metal sleeve to be inserted into it. This prevents the pipe from collapsing. Push the nut over the pipe and fully insert the pipe into the fitting. Tighten the nut. If we remove If we remove the pipe from the fitting we can see that the rubber sealing washer is successfully around the pipe creating a watertight seal. And that’s how push fit fittings work.

  1. one observation a made is that the fitting was assembled on the pipe, as far as my knowledge on Hep2o goes. being a pushfit, the backnut should be left in place and not removed to form a joint. so the fitting should be fulle assembled and the pipe pushed into the fitting to ensure a correct joint. the fitting should also be clean. i realise that this was probably for the purpose of the video. Hep2o is a great product.

  2. Thanks for showing the internal parts of the fitting! Even though the model I bought isn't exactly the same, you helped to give me a general idea of how to put mine back together again after it accidentally fell apart. Great information, and again, thank you!

  3. Good vid and easily understood. Can those fittings hold under 60-80 lbs of pressure or are they just good for lower pressure pipes like sprinkler systems?

  4. Going to Home Depot and see if they have it.I bought compression fittings but they didnt hold.Will try this over the weekend.Thnx plumberparts.

  5. I've rarely ever used these – only when supplied with showers or water softeners (when I cant get a compression fitting on). Over in Ireland we only really use Tec-Tite or compression fittings for such connections – although I prefer to solder or silver solder any hot connections.

    Any idea on what pressure they'll hold when hot water is run through them?

  6. I suggest you read the instructions that come with the fittings. They are called push fit for a reason. You show them being used as a compression fitting but they should not be taken apart before fitting them to the pipe.

  7. I was referring to the part in the video where you instruct the user to "push the nut over the pipe and fully insert the pipe in the fitting before tightening the nut."

  8. plumbers…they're all cowboys now !!!!!. Push fits & flexibles. Makes you wonder how many can actually bend a pipe & make a soldered joint. 🙁 !!

  9. Never trust plastic fittings, been let down too many times by them. As said below the generation of plumber these days struggle when it comes to working with copper yorkie, outer lite fittings. And it's actually a laugh when they try to use a bending machine.

  10. Just what I was looking for. Need to replace my worktop and this is what holds the sink pipes together. Cheers for the info.

  11. Created an assembly out of these (T junctions pipe and elbows) that took water from entry black pipe into the house from the floor, to control: cold sink tap, dishwasher feed, washing machine feed, outside tap, cold water out of kitchen to other parts of the house and tank. One of the elbows busted twice creating small flood. Eventually on 3rd attempt so far it holds together. Quite worried about it, turn the water off at night. It vibrated an bam!! it came apart shooting the pipe backwards.

  12. I think from reading this page's comments that most people are successful for radiator jobs. I had a huge scare on mains pressure. It would seem to me that ensuring a 90 degree bend is clipped so it cannot move is important because otherwise with the bangs of pressure from water mains and closing and opening of taps it can get undone. So can we really trust it for mains pressure applications?

  13. Mistrust in plastic is irrational. Copper gets expensive. Plastic: easy to cut, bend, work with. Fittings are watertight – even cold main isn't very high pressure, after all. Most problems from bad technique, cutting pipe clumsily or omitting pipe end stiffener! Professionals use plastic. Of course, if pipe might come apart thru stress, copper is an option. It's mechanically end/end stronger than pushed on connector. But push-fit is much better when breaking and re-making a joint. No flame!

  14. They can take a bit of practice if you are new to them. It's easy to make a joint with these that leak if you don't understand how they work under pressure. For instance I did everything by the instructions but joint leaked, and I found it was because the pipes were pushing together with the way they were sitting when I was done, so the fitting was loose. I found that the ends of the pipes need to be pulling apart from each other otherwise the seal doesn't form.

  15. Thanks. Nothing has not leaked since. I made a slight mistake. I chose one of those plastic Venturi type Speed fit valves for the hot but they are not full bore and on gravity it reduced my hot water flow. Was going to replace for a full bore but maybe am going for a 150 litre high pressurized hot water tank in combination with my system boiler. Once the pressurised hot water is in place I have to see that Speedfit stuff holds. Still, the plastic valve has a temperature limit another concern.

  16. Yeah, the temperature limit isn't good. I have push fit valves at the ends of my tap fittings and they have a max temp of 65c. I've seen my boiler get very close to that even though I've got the temperature turned all the way down (I don't think the regulator works) so it's always a worry

  17. There exists a metal version full bore pressurized fitting. I have got it but I am waiting for the opportune moment to swap it over.

  18. Thank you for these wonderful tips! I think the speed of making a connection with push fit fittings is perhaps the biggest advantage. In an emergency you can quickly cap or repair a pipe by simply pushing on a push fit fitting.

  19. Blimey mate, your vids were as boring as everyone else's back in the day! Glad to see you sorted it though, best plumbing vids on youtube now.

  20. Great Videos PP. I've learned bundles from them. Question though – If I'm teeing off from a flow and return to fit a new rad', can I use plastic push fits Tees going from existing copper to plastic pipe and back to copper again for the pipes that will be on show?

  21. Different types of pushfit/speedfit fittings for example the common one "john guest" my question is are some push fittings better than others? Or do they all do the same job? Cheers

  22. I had a PVC pushfit cap but I didn't understand what it was or how it worked. Just fidgeting, I slipped it over the end of a stick that's part of a $200 exercise device and was completely surprised when I couldn't get it off. Is there any way to get it off, or is that exercise device ruined? (It's just 2 weeks old.)

  23. This is the old hep2o system. They changed to a white system a good few years ago and now you need a tool to get pipe out once inserted. Speedfit is by far the best and easiest system

  24. o-rings have been used in automotive applications for years, operating under very arduous environmental conditions. So this type of joint seems very natural to me.

  25. I am looking to purchase this type of fitting in Melbourne Australia & so far no luck. Anyone who can help. Really appreciated.

  26. is there such a thing as a reducing pushfit… need to go from twenty five mil copper to fifteen mil plastic or polyplumb

  27. I dunno about hep20 fittings, but I know if you install polyplumb fittings in this way, the warranty’s void cos you’ve dismantled it, they say you’ve gotta leave the nut on when pushing the pipe into the fitting.
