Aligning.
The procedure of setting one part on or against another, such as a socket on a wall, with the help of a measure and spirit level in order to obtain a good line and fit. Feltham Plumbers carry out this action.
Airlock.
An airlock is a trapped pocket of air in a pipe which cuts off the water supply to a tap. This possible cure is to get a length of garden hose, slip it over the affected tap and the kitchen cold water tap and turn them both on to clear.
Cistern.
This is another name for a water storage tank. For example, both the tank behind the WC and the cold water storage tank in the loft can be called cisterns.
Draincock.
This is the lowest tap in an appliance (such as a boiler or radiator) or system, from which water can be drained. To drain the system, you simply slip a garden hose on the drain cock, run the other end of the hose out into the garden and then turn on the tap.
Rising main.
This is the cold water pipe that runs from the water suppliers stopcock to feed water (under pressure) to the kitchen tap and cold water storage tank in the loft. This should be the first valve to be closed in an emergency.
PTFE Tape.
This is a thin, ribbon-like plastic material used to seal threaded fittings. In action, the tape is wrapped around the thread and the joint is tightened up so that the tape fills the ‘V’ section part of the thread. Many plumbers prefer to use the traditional method of wiping the thread with a mastic made from putty, and then finishing by winding over a thread of hemp fibre. A Feltham Plumber uses this tape.
Fused connection unit.
A unit that allows a junction between a higher rated cable and a lower rating cable or flex, with a fuse that will blow to prevent the smaller cable being overloaded.
