If the Speedfit pipe has been cut correctly the insertion mark on the pipe will be level with the collet head Pull to check connection is secure and test the system Twist & Lock Fittings Twist the screwcap until it touches the body flange. This increases the O-Ring seal around the pipe and locks the pipe into position If you are not using collet clips, ensure that the screwcaps are in the locked position. Pull to check it is secure Premium Piece On every product John Guest Speedfit make, you’ll find the JG monogram proudly stamped, as a mark of trusted authenticity and quality.

Review: Perfect item works with no issues - From the time I got my pipe cutting tool out, turning the mains stop cock off and fitting this item it took all of 8 minutes to complete the job. So very simple to fit and use. I recommend watching some of their speedfit videos to see how well made these are and how simple it is to fit. Sometimes you hear of plumbers moaning about speedfit but it is only because speedfit have made a product that members of the public with limited knowledge can use these thus doing some plumbers out of money. Provided you use the recommended parts for what it is your project needs there is no problem. I am certainly no plumber believe me and when last year I fitted lengths of piping under the floor boards from the front of the house to the rear garden my wife had visions of our garden furniture floating down the street. No worries whatsoever, not a drip from any of the connections etc and it has been through the 2018/19 winter without any problems. Fully recommend this to anyone.

Flow can be variable, so I would say the answer is yes. **Q: Does it turn off clockwise ? So stiff I cant move it and dont want to force it.** A: the JOHN GUEST - 15MM EMERGENCY SHUT OFF TAP does turn off clockwise, the stiffness is to ensure that no excess water is dripping through the tap. **Q: Can these be used on a rubber cold water pipe?** A: They could but its not 100% what its designed for **Q: Would this be suitable for between an hot water tank & inlet to shower pump?** A: I can’t see why not. I have them fitted to my shower and generally have had no problems with JG push fit fixings or plastic piping so far ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect item works with no issues *by M***H on 22 December 2019* From the time I got my pipe cutting tool out, turning the mains stop cock off and fitting this item it took all of 8 minutes to complete the job.
