The ability to unscrew and remove the fitting with ease makes it ideal for areas where it may be necessary to occasionally strip down; waste pipes are the prime example – particularly where there is a water trap fitted to the bottom of a basin or tub. It means that you can easily access the trap for removal and cleaning.
Compressing?
As the name implies, the watertight seal of the fitting is reliant on the compression of a rubber ‘washer’.
It is usually shaped as a near conical, allowing for a better seal with less force applied. As the ‘nut’ tightens up against the fitting, it squeezes the seal into a chamfered area on the fitting, the angle of which matches the conical shape of the seal.
Leaks
It is still possible to get leaks with these types of pp compression fitting, but in our experience, that is usually an error on the part of the fitter; over-tightening the fitting can squash and deform the seal, under-tightening means that the seal isn’t mated to the fitting... less
