Spears® evaluation and review has shown these products to be compatible with satisfactory performance in normal installation of CPVC products. However, the potential for compatibility problems can be present in installations where CPVC materials are highly stressed. Such situations include, but are not limited to, inadequate compensation for thermal expansion and contraction, excessive bending beyond specified limits, improper pipe hanger or anchor selection or installation, over tightening of threaded joints, and other improper CPVC installation practices yielding high stress loads. Proper installation of each product in accordance with the manufacturer’s published Installation Instructions, Spears® FlameGuard® CPVC Fire Sprinkler Products Installation Instructions, EverTUFF® CTS Design and Installation Manual, and LabWaste® CPVC Corrosive Waste Drainage System Installation Instructions is essential. PLEASE NOTE: Not all products listed are suitable for all applications. Check product requirements.

*Cutting oils have potential to cause damage to PVC / CPVC systems. Wet, oily surfaces should be wiped clean to prevent the accumulation of residual oil. Systems should be flushed to remove any oils or debris before testing.

**Spray foam products must be properly mixed prior to contact with CPVC.
Damage can occur if unmixed, improperly applied product contacts the CPVC system.
Application care must be taken to ensure the exothermic reaction does not result in CPVC system damage.
