Also,
In general, the joints of AMERICAN push-on pipes are purposefully “tight,” and most joints require an assembly force of about 100 to 200 pounds or more of assembly force per inch of pipe diameter (i.e. a 12" joint might require about 12 x 100 or 1,200 pounds of assembly force).
In addition, A restrained joint is a special type of push-on or mechanical joint that is designed to provide longitudinal restraint. Restrained joint systems function in a manner similar to thrust blocks, insofar as the reaction of the entire restrained unit of piping with soil balances the thrust force.
Next,
generally, flanged is used above ground. Mechanical is usually used where thrust restraint is needed. The more common type is bell and spigot joints which are the cheapest and easiest to install. These are only suitable for long runs of straight pipe where thrust restraint is not necessary.
Consequently,
The only advantage over push-on joints is that in pipe sizes commonly used in distribution systems (say 16” and smaller) mechanical joints have a slightly larger allowable deflection. The water supplier should have standard details that would cover almost all common situations (tees, valves, bends, hydrants etc.).
