Building regulations have forced facilities and homes to stop allowing polybutylene pipes for water supply lines from being installed. But what do you do if you already have these pipes and you have a faulty shut-off valve? According to eHow.com the valve can be cut off the line and replaced with a CPVC shut-off valve. The CPVC pipe attaches to each side of the vale, which in turn connects to the polybutylene pipe with adaptor couplings. For instructions visit ehow
Once you’ve fixed your valves it’s critical to mark all your pipes. Almost every industrial and commercial piping system contains hazardous fluids and gases, and their release can cause severe personal injuries or property damage.
