I recently finished plumbing my system using a combination of flexible and rigid PVC. The ideal method for adhering is to clean all surfaces to be glued, apply primer to both the male and female parts (you can use clear priming if you prefer the look of purple primer).
While ABS is a little bit tougher and can withstand a larger shock or impact, PVC pipe is more flexible than ABS. PVC also has the benefit of being better at reducing the sound of water flowing through the pipework.
However, in terms of cost, ABS and PVC pipes are often about equal. Although priming is needed to install PVC piping, which is an extra expense that tends to level the overall price point or make PVC marginally more affordable, the prevailing consensus is that ABS may be slightly more expensive.
When notable price variations occur, it's typically because one type's delivery is more expensive than the other. The primary distinction between these materials is that the PVC method requires two steps for pipe connection, whereas the ABS pipe has a single step.
PVC is also much harder on tools, and when it is cut, there are more burrs that need to be smoothed out before priming, which takes even longer. Therefore, ABS will still be less expensive over time despite the initial price differential.
While joining ABS to PVC is technically feasible, it should only be done mechanically-not with glue.
PVC has a maximum service temperature of 140° F for pressure applications and is only meant to be used with cold water. Not only is CPVC more temperature resistant than PVC, but it also performs better within PVC's operating temperature range.
Despite PVC's great rigidity, this method lets you bend it at angles of up to 90 degrees without it kinking. PVC pipe is frequently utilized for irrigation and as electrical conduit.
A thermoplastic extrusion polymer used in a wide range of plastic profiles is called flexible PVC.
The following bending techniques will be encountered: roll bending, rotary draw bending, compression bending, and mandrel tube bending. Depending on the goal, each of these procedures produces a precise bending that qualifies the pipe for use.
