CPVC is resistant to water temperature

  • 93⁰C for SHORT term application

  • 82⁰C for CONTINUOUS application

It keeps hot water hotter and cold water colder than copper plumbing

INSTALLATION PROCEDURE FOR CPVC FOR SOLAR APPLICATION

a. Installation guidelines for using cPVC piping with Solar Water Heaters

  • Connect minimum 1 mtr. length of metal pipe to the outlet of hot water tank.

  • Ventilation – proper air-venting on the hot water outlet side is a must

  • Use of expansion loop is highly recommended to avoid snaking effect caused due to expansion and contraction of pipe.

  • Although CPVC has the lowest thermal conductivity amongst all alternate plastic plumbing systems, however to maintain thermal efficiency, it is recommended that the pipes be insulated. PE foam may be applied over the pipe to provide adequate insulation.

b. Horizontal and Vertical spacing for pipe supporting (clamping of pipes)

Assembly

  • a. Dry fitment – check joint of pipe to fitting without solvent cement should fit up to 60 – 70%

  • b. Cold fusion joint (cold welded joint)

  • c. For diameters ½” to 2”, single step solvent cement.

  • d. For diameters 2½” to 4”, 2 step solvent cement (Primer + Solvent Cement)

  • e. Primer helps to clean the surface of pipe & fitting and softens the material.

  • f. Set time – After application of solvent cement, it takes some time for the joint to set, subject to atmospheric conditions and pipe diameter

Average initial set schedule for CPVC solvent cement

Temperature Range Pipe size ½” – 1¼” (20mm – 40mm)
16⁰ – 38⁰C 2 minutes
5⁰ – 16⁰C 5 minutes
– 18⁰ – -5⁰C 10 minutes

  • g. Cure time – Curing time is longer time than the set time. Curing means the joint has completely matured.

Average joint cure schedule for CPVC solvent cement

Relative Humidity 60% or less Pipe size ½” – 1¼” (20mm – 40mm)
Temperature ranges during assembly & cure periods Bar
