Plastic Pipe Cements and Primers
FAQs
Q Can I use Oatey CPVC cements for lines which carry Deionized water?
A Yes.
Q What cement is used to bond exible pipe and ttings?
A Oatey Rain-R-Shine or PVC Flexible cements can be used for this application.
Q How long do you allow CPVC pipe to cure before introducing uids and/or pressure?
A You can use the online charts to calculate the cure time for your specic application. If you need further
help with cure times, please contact our technical department.
Q There is a taste and odor in the CPVC water lines shortly after installation, how can I solve
these issues?
A Oatey cements and primers have outside lab approval for lines that carry drinking water (NSF). The
plumbing system carrying the water should be drained by rst shutting the water off at the water meter,
which is most commonly found in the basement on the front wall facing the street. If you have a home on
slab, it should be in the mechanical room with the furnace and water heater. Open all faucet valves and
allow the interior piping system to air dry overnight. This will allow most of the remaining vapors from the
cement and primer to dissipate and escape. Air movement is a huge plus.
Q Are Oatey cements safe to use on water lines that carry drinking (potable) water?
A All Oatey PVC and CPVC solvent cements have been tested to NSF standards and are approved with use
on drinking (potable) water systems.
Q Can PVC cements be used to assemble CPVC pipe/ttings?
A No. The PVC cements are too aggressive and will cause probable failure to the CPVC pipe and ttings and if
it was used, the joints should be cut out and replaced. If CPVC cement was accidentally used to bond PVC
joints, it would not be necessary to replace them but future joints should be assembled with correct cements.
