Joints

Making The Joint:

Firstly you should cut the ends of each piece of pipework and make sure they are nice and clean, you can do this with some wire wool and also clean the olives. Take the new joint apart and put the cap nut over one pipe end, then, the olive. Check that the sloping sides of the olive are equal in length. If one is longer than the other, then, that side should face away from the nut. Press the pipe firmly into the joint body and twist to make sure it is firmly against the integral stop. A Hornsey Plumber can use compression joints. Move the olive up against the joint body, and hand tighten the nut. The olive needs to be compressed just enough to ensure a watertight joint. Make a mark on one face of the nut and on the opposing face on the joint’s body, then, holding the body still with a spanner, using another spanner, turn the nut one complete revolution. Put together the other half of the joint in exactly the same way. Plumbers will wrap a single turn of PTFE tape over the olive before tightening the nut, to guarantee a watertight seal. A correctly tightened compression joint should be watertight without the tape. Hornsey Plumbers use compression joints.

Metal Push Fit:
Metal push fit joints can be used instead of the plastic joints. These joints comprise of a one-piece body made from brass alloy, which consists of a release mechanism for easy removal and a grab ring made from stainless steel to keep the fitting secure. This type of connector is very fast to use and not as big as the plastic versions and they also have the capacity to stand very high water pressure. The down side is they are quite pricey.
