MUNICIPEX water service


MUNICIPEX® water service is engineered specifically for water service line applications that run from the main to residential and commercial structures.

Manufactured by REHAU, MUNICIPEX water service is offered in diameters 3/4 to 2 in. and in coil lengths of up to 1,000 ft (304.8 m). Backed by a 25-year limited warranty. 

Installation options

  • Compatible with AWWA C800 fittings using standard pipe wrenches. No specialized tools required.
  • 2 in. MUNICIPEX water service can be tapped with a service saddle. See REHAU Technical Bulletin 259 for clarification.
  • Using a squeeze-off tool to temporarily stop the water flow through MUNICIPEX water service will not cause permanent damage or deformation to the service line, and is the fastest and cleanest way to temporarily stop flow.
