Dismantle a new joint and slip a cap nut over the end of one pipe, followed by an olive. Look carefully to see of the sloping sides of the olive are equal in length. If one is longer than the other, that side should face away from the nut. Push the pipe firmly into the joint body, twisting it is likely to ensure it is firmly against the integral stop. A
Waterloo Plumber can use compression joints.Slide the Olive up against the joint body, and tighten the nut by hand. The olive must be compressed by just the right amount to ensure a watertight joint. As a guide, make a pencil mark on one face of the nut and on the opposing face on the joint body, then, holding the joint body steady with a spanner, use another spanner to turn the nut one complete revolution. Assemble the other half of the joint in exactly the same manner. Some plumbers like to wrap a single turn of PTFE tape over the olive before tightening the nut, to make absolutely sure the joint is watertight. However, a properly tightened compression joint should be watertight without it.
Waterloo Plumbers use these joints.A Quick Note on Metal Push Fit Joints.Metal push fit joints are available as an alternative to the plastic variety. Made from brass alloy, they have a one-piece body that incorporates a stainless steel grab ring to prevent the fitting coming loose under pressure. A release mechanism is incorporated to make them easy to remove. They are quick to use, less bulky than the plastic counterparts and better able to withstand higher water pressures, but they are more expensive, especially if you are carrying out a major project.
