AquaPex Piping
Most of our water pipe distribution systems are type L copper tubing and fittings. However, there has been a great demand for the newly MA approved AquaPex type systems. These systems are installed using plastic tubing for reduced installation labor. These systems offer many benefits including greater resilience to freeze damage, reduced labor in installation, and routing preferences that isolate fixtures in the mechanical room. We have installed several of these systems and are happy to further discuss the benefits of AquaPex.
